Emerson Hancock's Ratios Creating a Sell-High Window?

Seattle Mariners starting pitcher Emerson Hancock has been a useful ratio stabilizer, and that is exactly why fantasy managers should at least see what his trade market looks like. The 27-year-old is 6-4 with a 3.23 ERA, 1.01 WHIP, and 92 strikeouts over 97 2/3 innings. He also just shut down the Toronto Blue Jays on Sunday, throwing seven scoreless innings with two hits allowed and five strikeouts in a 4-0 win. That kind of surface line plays in any format, but it is not spotless underneath. Hancock has allowed a .322 xwOBA, 43.6% hard-hit rate, 90.0 mph average exit velocity, and 9.5% barrel rate, so there is still damage risk if the command backs up. He is not someone to dump for a weak offer. If another manager is buying the ERA and WHIP as a full breakout, though, selling makes sense.

Brendan Donovan Could Start Rehab Assignment Any Day Now

Seattle Mariners infielder/outfielder Brendan Donovan (groin) worked out on Tuesday in Arizona and will go through another workout on Wednesday, according to Ryan Divish of The Seattle Times. The hope is that he will start playing in minor-league rehab games in the rookie-level Arizona Complex League after that. The 29-year-old utility man is making progress, but he's not going to be ready to rejoin Seattle's major-league roster before the end of the first half of the season this Sunday. Depending on how Donovan's rehab assignment goes, though, he could be ready for the start of the second half on Friday, July 17. The former seventh-rounder of the St. Louis Cardinals in 2018 out of the University of South Alabama was expected to be a key contributor for the M's in 2026, but he's managed to play in just 25 games due to injuries, going 23-for-84 (.274) with three homers, eight RBI, nine runs, and a stolen base. Donovan is more attractive in real baseball than fantasy because of his low power/speed ceiling, but he hits for average and is eligible at second base, third base, shortstop, and outfield in Yahoo leagues. He's currently rostered in just under half of Yahoo leagues.

Bryan Woo's Road Struggles Masking Second-Half Value?

Seattle Mariners starting pitcher Bryan Woo has not been automatic away from home, and that may be the only opening fantasy managers get in trade talks. The 26-year-old gave up nine hits, one walk, and four runs, three earned, over five innings Tuesday, July 7, against Miami. His home-road split is hard to ignore, with Woo sitting at 6-0 with a 2.10 ERA in Seattle and 1-6 with a 6.28 ERA on the road. The full profile is still a lot better than the road blowups. Woo has a 4.23 ERA, but the 1.07 WHIP, 102 strikeouts, 20 walks, and 3.06 FIP are not the numbers of a pitcher to panic-sell. Since he is already rostered in roughly 98% of leagues, this is a trade-market play, not a waiver chase. Check in if his manager is annoyed, but do not sell low.

Is Ryan Sloan the Next Mariners Pitcher to Debut?

Seattle Mariners right-handed pitching prospect Ryan Sloan has spent the entire 2026 season at the Double-A level but has been overshadowed by his teammate Kade Anderson. While Anderson has recently jumped Sloan on the team prospect board (on MLB.com), Sloan possesses nearly as much upside, sitting as MLB.com's No. 8 overall prospect and the team's No. 2 overall prospect. Through the first half of the 2026 season, the 55th overall pick from the 2024 MLB Draft has posted a 4.04 ERA and 1.19 WHIP over his first 62 1/3 innings at Double-A. He has struck out an impressive 77 hitters and walked only 12. During the 2025 season, Sloan made his professional debut and tossed 82 innings with a 3.73 ERA and a 1.16 WHIP over stints in the lower levels. Given Sloan's previous professional experience, the Mariners could turn to him first, rather than Anderson, when they need depth down the stretch. For now, Sloan is worth close monitoring, as a promotion to Triple-A could be imminent.

Dominic Canzone has Earned a Full-Time Role

Seattle Mariners outfielder Dominic Canzone has earned a full-time, middle-of-the-order role in Seattle's lineup going forward, according to Adam Jude of The Seattle Times. "He's earned it," president of baseball operations Jerry Dipoto said. The 28-year-old left-handed-hitting outfielder is currently hitting .273/.349/.551 with a .900 OPS, 14 home runs, 37 RBI, 32 runs scored, and a stolen base in 205 at-bats in 2026 in his third full season with the M's. He already has a career high in home runs, RBI, and runs scored in 78 games and 232 plate appearances. All four of Canzone's starts against left-handed pitchers have come in the last month, and he's gone 6-for-22 (.273) against southpaws, with two of his 14 home runs on the year. Under the hood, Canzone's xBA of .282 and xwOBA of .383 (wOBA of .384) back up his first-half breakout. He ranks in the 84th percentile in hard-hit rate, the 94th percentile in barrel rate, and the 96th percentile in xSLG. Canzone should be a priority waiver-wire pickup in fantasy leagues for those who need slugging help in the outfield.

Kade Anderson's Elite Double-A Production Makes him a Priority Stash

Seattle Mariners pitching prospect Kade Anderson suffered his first loss at Double-A Arkansas following his July 3 start. He only allowed two earned runs to pick up his first loss of the season in his 8-1 overall record. His numbers look video game worthy with a 1.36 ERA and 0.69 WHIP with 108 strikeouts in 72 2/3 innings pitched. The No. 3 overall draft pick out of LSU has dominated the minors in his first season of professional baseball. Before a stop in Seattle and a spot in the Mariners rotation, Anderson would likely need some seasoning at Triple-A. So while his numbers call out for a stash for fantasy managers, some patience is required. Managers in mid-size leagues would be smart to use a roster spot now on Anderson and wait to see if it pays off. The prospect pedigree looks elite for Anderson, and it's worth using an early roster spot to acquire his services.

Michael Arroyo to Join Triple-A Tacoma, Emerging as Viable Stash Candidate?

Seattle Mariners infield prospect Michael Arroyo was promoted to Triple-A Tacoma earlier on Sunday evening, according to Daniel Kramer of MLB.com. Arroyo is currently viewed as the team's No. 5-ranked prospect and the overall No. 45 prospect on MLB.com. The infielder has spent the first half of the season in Double-A and is being rewarded with an early promotion. Across 65 games with Double-A Arkansas, Arroyo has posted a strong .287/.364/.456 line with 12 doubles, 10 home runs, and 13 stolen bases. Last summer, Arroyo split his time between High-A and Double-A, where he carried an overall .262/.401/.433 line with 17 home runs and 12 stolen bases. While an MLB debut may not occur until late in the season, his five-category profile makes him a worthy stash candidate in deeper 15-team leagues with N/A spots as he is now on the doorstep of the majors.

Mariners Promote Lazaro Montes to Triple-A, Late-Season MLB Debut in Play?

The Seattle Mariners are promoting top-ranked hitting prospect Lazaro Montes to Triple-A. Montes is viewed as the overall No. 27-ranked prospect in the sport on MLB.com hand has been among the elite class of power hitters in the minor leagues this season. Through 79 games with Tacoma, the 21-year-old has posted a .234/.369/.550 line with a dominant .990 OPS. Over this stretch, Montes has gone deep 25 times, tacked on 11 doubles, and chipped in five stolen bases. However, his recent surge likely prompted his promotion. Over his last 22 games, Montes has showcased his elite raw power, posting a dominant .958 OPS and seven home runs. Managers should pay close attention to his status at Triple-A, as a hot start could open the door for a late-season debut.

Brendan Donovan to Start a Rehab Assignment on Tuesday

Seattle Mariners infielder/outfielder Brendan Donovan (groin) will start a minor-league rehab assignment on Tuesday, according to Ryan Divish of The Seattle Times. Donovan has been sidelined with a strained left groin since the middle of May, but barring a setback on his rehab assignment, he could return just before the All-Star break and play with the M's next weekend. The 29-year-old former seventh-rounder by the St. Louis Cardinals in 2018 from the University of South Alabama was a first-time All-Star in 2025 in his final year in St. Louis, slashing .287/.353/.422 with a .775 OPS, 10 homers, 50 RBI, 64 runs scored, and three stolen bases in 118 games and 515 plate appearances. Donovan has a limited fantasy ceiling because of his middling power and speed, but his high-contact approach makes him appealing for his high average and on-base percentage, not to mention he's eligible at second base, third base, shortstop, and the outfield in Yahoo leagues. He's currently rostered in just under half of Yahoo leagues.

Lazaro Montes Continues to Flash High-End Power, Is a 2026 MLB Debut Still in Play?

Seattle Mariners top-ranked outfield prospect Lazaro Montes has showcased high-end power upside at the Double-A level this season. Through 77 total contests with Double-A Arkansas, the slugger has launched 25 round-trippers with a .236/.368/.561 line. During this stretch, he has posted a .929 OPS with a 99:51 K:BB. However, he has been even more impressive as of late. Over his last 28 contests (since June 1), the 6-foot-5 hitter has gone deep 13 times while holding a sharp .281/.439/.729 slash line. Last summer, Montes split his time between High-A and Double-A. Given that he has taken his production up a level over the past month, an early call to Triple-A in the second half remains in play. Managers in deeper redraft leagues should continue to monitor his status, as a late-season call-up during the stretch run is not out of the question.

Julio Rodríguez • CF • Mariners

Julio Rodriguez Heading to Concussion Injured List

Seattle Mariners outfielder Julio Rodriguez (head) is expected to be placed on the seven-day concussion injured list on Friday, according to Daniel Kramer of MLB.com. The Mariners haven't made an official roster move yet, but utility man Miles Mastrobuoni has a locker at T-Mobile Park in Seattle and is likely to be called up from Triple-A Tacoma as the corresponding roster move. Victor Robles (forearm) replaced Rodriguez on Thursday in the game against the division-rival Los Angeles Angels after Rodriguez was hit in the helmet by a throw, but he was forced to leave early as well with a right-forearm injury. If Robles is unavailable to return on Friday, either Mastrobuoni or Weston Wilson will likely enter the starting lineup in Seattle's outfield, with Luke Raley most likely sliding over to center field. It's unclear if Rodriguez will be able to rejoin the M's before the All-Star break in mid-July. The five-category producer should be stashed in all fantasy leagues while he recovers. He's currently hitting .259/.323/.424 with a .747 OPS, 14 homers, 40 RBI, 46 runs, and 12 stolen bases in his 344 at-bats in 2026.

Kade Anderson • SP • Mariners

Is Kade Anderson the No. 1 Stash Target as he Continues to Deal at Double-A?

Seattle Mariners starting pitching prospect Kade Anderson has turned in a dominant June at Double-A Arkansas and is coming off a start in which he allowed his first two earned runs of the month. Overall, he completed June with a 4-0 record and an 0.79 ERA with 32 strikeouts in 22 2/3 innings pitched. It doesn't get much better than that at any level, and fantasy managers would like to see Anderson and his lefty dominance at the Triple-A level sooner rather than later. Anderson has shown a mastery of Double-A with an 8-0 record and 1.22 ERA with 99 strikeouts in 66 2/3 innings pitched. The talented former No. 3 overall pick would likely need some time in Triple-A before the Mariners take a look at him in Seattle. But his numbers show that he could be ready for a close-up and is definitely worth picking up and stashing off the waiver wire in leagues of all sizes.

Julio Rodriguez Removed Early on Thursday After Being Hit in the Head

Seattle Mariners outfielder Julio Rodriguez (head) was removed from Thursday's game early against the division-rival Los Angeles Angels to begin the top of the third inning, shortly after taking a throw off the back of his helmet, according to Daniel Kramer of MLB.com. Victor Robles took over for him in center field. Before leaving, J-Rod walked in his only plate appearance. The Mariners will most likely put him through the concussion protocol, so fantasy managers will want to check back later on or early Friday morning for an update. For now, we'll consider the 25-year-old three-time All-Star as day-to-day. Rodriguez came into Thursday's contest with a .259/.321/.424 slash line, .745 OPS, 14 home runs, 40 RBI, 46 runs scored, and 12 stolen bases in his 344 at-bats for Seattle. The five-category fantasy contributor is rostered in 99% of Yahoo leagues for a reason, and he's a must-start in all formats when he's active. Rodriguez is currently riding a seven-game hitting streak in which he's gone 12-for-29 (.414) with three RBI, two stolen bases, and four runs scored. UPDATE: Rodriguez is in the concussion protocol and will be re-evaluated on Friday.

Luke Raley Returning on Thursday Against Angels

Seattle Mariners first baseman/outfielder Luke Raley (forearm) is starting in right field and will bat seventh in his return to the starting lineup on Thursday against the division-rival Los Angeles Angels and right-hander Walbert Urena, according to MLB.com. Raley will return for the M's after sitting out the last three games due to soreness in his left forearm. Due to injuries and poor play recently, the 31-year-old veteran left-handed slugger is only rostered in 12% of Yahoo leagues with the first half of the 2026 season winding down. All 14 of Raley's home runs this year have come against right-handed pitching, but he's coming off a month of June that saw him hit a putrid .125 (7-for-56) with one homer, two doubles, four RBI, three runs scored, four walks, and 20 strikeouts in 19 games across 61 plate appearances. Nobody should be in a rush to throw him back into their starting lineups, especially not in DFS. Raley has never faced Urena in his career.

Luke Raley Still Out With Forearm Injury

Seattle Mariners first baseman/outfielder Luke Raley (forearm) is sitting out for a third straight game due to a forearm injury in Tuesday's game against the division-rival Los Angeles Angels, per MLB.com. Weston Wilson is making the start in right field for the M's and is batting ninth against Angels right-hander Jose Soriano. Raley remains day-to-day for now, and it's unclear if his forearm injury is serious enough to land him on the 10-day injured list. The left-handed-hitting slugger has been pretty beat up of late and has hit just .125 (7-for-56) with a homer, two doubles, four RBI, three runs scored, four walks, and 20 strikeouts in 19 games played during June. Raley is now only rostered in 13% of Yahoo leagues after his tough month of June. His upside is limited in mixed fantasy leagues because he's in a platoon in Seattle's outfield against right-handed pitchers. Despite a .283 average (49-for-206) on the year, Raley does have some value for his left-handed pop (14 homers) in the right matchups when he's in the starting lineup.

Lazaro Montes Gets Back on Track, Promotion Now in Sight?

Seattle Mariners outfield prospect Lazaro Montes had a brutal 1-for-27 (.037) stretch with a .188 on-base percentage from June 16 through June 24, but in the four games since, the left-handed hitter is 6-for-10 (.600) with seven walks and a hit-by-pitch, leading to an astounding .778 OBP during that time. The Mariners' fourth-ranked prospect is hitting just .239 on the season, but a high 14.2 percent walk rate has buoyed a solid .361 OBP, and his 23 home runs (second-most at Double-A) anchor a .556 slugging percentage. The team would surely like to see some developmental progress on his 29.0 percent strikeout rate, and if the 6-foot-5 slugger's recent approach is any indication of that progress (7:3 BB:K), he could be headed to Triple-A soon. With the kind of power the 21-year-old possesses, he could become a stash candidate later in the year, so keep an eye out for any developments.

Cole Young Stays Hot in June, Hits Two Home Runs on Monday

Seattle Mariners second baseman Cole Young continued to swing the bat well in the team's 6-2 win over the division-rival Los Angeles Angels at T-Mobile Park on Monday, going 3-for-3 with two home runs and three RBI to boost his season average to .260 and his OPS to .713. It was the 22-year-old's first multi-homer game of his young career. Although Young's season line might not impress anyone, he has picked things up in June and has gone 30-for-102 (.294) with five home runs, two doubles, 11 RBI, and 11 runs scored in 26 games and 107 plate appearances during the month. The young middle infielder is now slashing .260/.321/.392 on the season with nine long balls, 40 RBI, 37 runs scored, and two stolen bases in his 311 at-bats in his first full year in the majors in Seattle. With an expected batting average of .277 and an xwOBA of .329 (wOBA of .304), Young's batted-ball profile suggests that his improvement in June is no fluke. If you need middle-infield help in deep-mixed fantasy leagues, you could do much worse than Young, who is only rostered in 11% of Yahoo leagues.

Brendan Donovan • 3B • Mariners

Brendan Donovan Could Be Nearing Rehab Assignment

Seattle Mariners infielder/outfielder Brendan Donovan (groin) will be reevaluated after the team's current homestand and could be nearing a rehab assignment, per Ryan Divish of the Seattle Times. Donovan has been on the 10-day injured list since mid-May due to a left groin strain, but it appears he could be nearing a return around the All-Star break. Across 101 plate appearances in 2026 for Seattle, Donovan has hit .274/.386/.452 with three home runs, eight RBI, nine runs scored, and one stolen base. The 29-year-old does not offer much speed or power upside for fantasy managers, but he's a steady source of batting average when healthy. Seattle will have to shift some pieces around when Donovan returns, as the team's infield picture is crowded following the promotion of shortstop Colt Emerson to the big leagues. Still, Donovan's ability to play multiple positions should keep him in the Mariners lineup on a near-everyday basis once healthy.

Luke Raley Still Out on Monday With Forearm Injury

Seattle Mariners first baseman/outfielder Luke Raley (forearm) is out of the starting nine for Monday's series opener against the division-rival Los Angeles Angels, according to MLB.com. It is the second straight start that Raley will miss due to soreness in his left forearm. Victor Robles is starting in right field again and will bat eighth against Angels right-hander Ryan Johnson. Raley should be considered day-to-day and could return to the starting lineup as early as Game 2 of the series at T-Mobile Park on Tuesday. The 31-year-old veteran left-handed slugger has interesting pop, but he lacks a ton of fantasy upside in mixed leagues because he doesn't play regularly against left-handed pitchers. In 206 at-bats this year, he's slashing .238/.302/.485 with a .788 OPS, 14 home runs, 35 RBI, 25 runs scored, and a stolen base in 73 games played. Raley has been awful in 19 games (61 plate appearances) in June, going 7-for-56 (.125) with a homer, two doubles, four RBI, three runs scored, four walks, and 20 strikeouts.

Dominic Canzone Back in Lineup on Monday as DH

Seattle Mariners outfielder Dominic Canzone (hamstring) is back in the starting lineup for Monday's series opener against the division-rival Los Angeles Angels and right-hander Ryan Johnson, serving as the designated hitter and batting third, per MLB.com. Canzone is back in action on Monday after sitting out Sunday's series finale against the Cleveland Guardians with right-hamstring soreness. The 28-year-old left-handed-hitting outfielder has been one of the team's most consistent hitters this year and already is up to a career-high 12 home runs, slashing .274/.349/.542 with an .891 OPS, 33 RBI, 29 runs scored, and a stolen base in 190 at-bats. He is hitting .323 (21-for-65) with five home runs, three doubles, a triple, and 11 runs scored in 22 games in June, but he's cooled off of late, going 3-for-23 with a homer, two RBI, three walks, and nine strikeouts in his last eight contests. Canzone lacks fantasy upside in shallow-mixed leagues because he rarely plays against lefties, but he's hitting a nice .281 (48-for-171) with 11 of his 12 long balls against righties this year.
