Is George Kirby Poised for a Second-Half Breakout?

Across 110 innings (18 starts) in 2026, Seattle Mariners starting pitcher George Kirby has recorded a 7-8 record with a 3.76 ERA, 1.32 WHIP, and 98 strikeouts. The 28-year-old's trademark command remains strong, as he owns a 5.3% walk rate on the year. However, Kirby's strikeout rate has dipped to 21.5% after he posted a career-best 26.1% strikeout rate in 2025. Still, Kirby's elevated WHIP and middling ERA are mostly symptoms of poor batted-ball luck. Opposing batters own a .343 batting average on balls in play against Kirby this season, well above his career mark of .310. Kirby's current strikeout rate limits his fantasy ceiling, but he's shown the ability to miss more bats in the past. If Kirby continues to limit home runs (0.90 HR/9) and sees some BABIP regression, he could emerge as a second-half riser.

Kade Anderson Leading the Way in Minors, Top Pitcher to Stash?

Seattle Mariners pitching prospect Kade Anderson capped off a spectacular first half of 2026 with a one-inning start in the All-Star Futures Game, facing four batters in the contest with his only blemish coming via a base hit yielded to MLB's No. 1 overall prospect, Jesus Made. The left-hander earned the start for the AL after posting a 1.36 ERA, 0.69 WHIP, and an elite 37.5 percent K-BB% in 72 2/3 innings pitched, all ranking best in the minors among pitchers with at least 60 innings pitched. The former third-overall draft pick looks poised to see some time at Triple-A in the second half and should have a good shot at making his major league debut later in the year. Given his workload, his 108 strikeouts equate to a fantasy-friendly 13.38 K/9, and although his debut is not imminent, the 22-year-old's stuff warrants stash consideration in all leagues with an NA spot for managers looking for pitching help.

Cal Raleigh's Power Collapse is More Than Bad Luck

Seattle Mariners catcher Cal Raleigh hit the break at .169/.271/.310 with nine home runs in 65 games, a brutal drop after last year's 60-homer season. The oblique strain explains some of it. Raleigh missed 33 days, returned June 16, and has not looked right for long stretches. Still, the underlying damage goes beyond a low average. His hard-hit rate has fallen from 49.6% to 32.5%, his barrel rate from 19.5% to 11%, and the strikeout rate is up to 32.5%. Statcast gives him only a .179 expected average and .356 expected slugging percentage. Seattle has kept him in the heart of the order, so the opportunity is not going anywhere. The old ceiling makes him tempting as a buy-low. Just don't pay for 2025. This version of Raleigh has real second-half risk.

Dominic Canzone Has Emerged as a Must-Add Power Bat

Across 254 plate appearances this season, Seattle Mariners outfielder Dominic Canzone is hitting .264/.335/.529 with 15 home runs, 40 RBI, 33 runs scored, and one stolen base. A lefty swinger, Canzone opened 2026 in a big-slide platoon role for Seattle. However, he's logged a .955 OPS in 30 plate appearances against left-handed pitching this season and has recently begun to emerge as an everyday player in the heart of the Mariners lineup. Canzone's splits against lefties could regress over a larger sample size of at-bats. Still, he owns strong underlying contact metrics with a 15.3% barrel rate and a 48.3% hard-hit rate. Canzone also limits swing-and-miss, as he's posted a respectable 20.9% strikeout rate. Now that he's working his way into a full-time role, Canzone profiles as a must-add power bat on the waiver wire.

Emerson Hancock has X-Rays Come Back Negative

Seattle Mariners starting pitcher Emerson Hancock (finger) was forced to make an early exit from Sunday's outing against the Tampa Bay Rays. Hancock was struck in the hand by a comebacker during the first inning of this game. He attempted to stay in the game, but Hancock was taken out in the second inning. He finished this outing with 1.2 innings of work and two strikeouts. Luckily, the X-rays came back negative, so it appears Hancock has avoided any significant injuries. The All-Star break begins on Monday, so Hancock will get a few days to rest before game action returns. The hope is that he'll be able to avoid a trip to the Injured List, and the Mariners can just slot him towards the back of the rotation to give him as much time as possible to recover.

Emerson Hancock Removed With Hand Injury

Seattle Mariners starting pitcher Emerson Hancock (hand) was forced to make an early exit from Sunday's outing against the Tampa Bay Rays. Hancock was struck in the hand by a comebacker during the first inning of this contest. He remained in the game afterwards, but was pulled in the second inning. His day will be finished with 1.2 innings of work and two strikeouts. The expectation is that Hancock will undergo further testing to determine the severity of the injury. Luckily, the All-Star break begins on Monday, so Hancock will get a few days off to rest. Fantasy managers should consider Hancock as day-to-day until further notice. UPDATE: X-rays came back negative on Hancock's palm and middle finger, according to The Seattle Times' Ryan Divish.

Lazaro Montes on the Stash Radar Amid Recent Promotion to Triple-A?

Seattle Mariners top outfield prospect Lazaro Montes was recently bumped up to the top club in the system following his impressive production at Double-A. To open the season, the 21-year-old carried a .234/.369/.550 line with a sharp .919 OPS over 79 contests at Double-A. During this stretch, Montes hit 25 home runs and chipped in five stolen bases. However, what prompted his promotion was the .253/.413/.614 line and 1.064 OPS he held over the final 25 games at Double-A. While the 21-year-old has gotten off to a slower start at Triple-A, going just 2-for-18 over the first four games, managers should continue to closely monitor his production as his power upside is among the highest in the sport. If Montes can find his footing, the No. 26-ranked prospect in the sport could compete for a late-season promotion to Seattle.

Kade Anderson Remains in Play for Second-Half Call-Up

Seattle Mariners top pitching prospect Kade Anderson has continued to showcase elite upside at the Double-A level during his first professional season. Through 14 total starts, the former LSU standout has posted an elite 1.46 ERA, 0.69 WHIP, and a sharp 108:10 K:BB over 72 2/3 innings. Over his last six outings, the left-hander has struck out at least eight hitters in all but one and has even hit the nine-punchouts mark in four of these outings. Overall, in his profile, Anderson has allowed two runs or fewer in 13 of his 14 starts, with his lone five-run outing on May 15 remaining a distinct outlier this season. However, given that Seattle has ample depth on their MLB roster, Anderson remains potentially far from a call-up. Despite this, his upside per start makes him an elite stash target in all 12-team leagues with N/A spots.

Julio Rodriguez Not Expected to Return This Weekend

Seattle Mariners outfielder Julio Rodriguez (concussion) is not expected to return from the seven-day concussion injured list to play this weekend against the Tampa Bay Rays, but the hope is that he'll be ready to go coming out of next week's All-Star break, according to Shannon Drayer. The Mariners are going to wait a bit longer to bring J-Rod back, even though he's eligible to return from the IL for Friday's series opener versus Tampa. The left-handed-hitting Luke Raley will continue to patrol center field for the M's when they face right-handed pitchers until Rodriguez returns. Before suffering a head injury, the 25-year-old Rodriguez was slashing .259/.323/.424 with a .747 OPS, 14 home runs, 40 RBI, 46 runs scored, and 12 stolen bases in 87 games played across 378 plate appearances in his fifth year in the big leagues. The three-time All-Star and former American League Rookie of the Year is a five-category contributor and has the ability to carry fantasy teams in the second half if he can stay together and get on a nice run.

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 • 3B • Mariners

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 • SP • Mariners

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.

Ryan Sloan • P • Mariners

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 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.
