Cal Raleigh Getting a Breather Against Lefty on Monday

Seattle Mariners catcher Cal Raleigh is not in the team's starting lineup on Monday for the series opener against the visiting New York Yankees at T-Mobile Park, according to MLB.com. Mitch Garver is doing the catching for right-hander Luis Castillo and will hit sixth against Yankees lefty Ryan Weathers. Raleigh is just getting a normal day of rest against a lefty pitcher. After breaking out in 2025, the 29-year-old left-handed slugger has gone just 2-for-15 to start the 2026 season with a double, an RBI, a stolen base, three walks, and 10 strikeouts in 18 plate appearances. It's not the start his fantasy managers had hoped for, but it's still very early. With Yankees ace Max Fried on the mound on Tuesday against the M's, Raleigh's rough start to the season could continue if he's back in the starting lineup.

Brendan Donovan Enjoys a Big First Series with Mariners

Seattle Mariners third baseman Brendan Donovan was highly productive at the plate during the first series of the regular season. Across four games, he went 6-for-14 with one double, two home runs, and four RBI. He also added two walks, two hit by pitches, and four strikeouts. The 29-year-old is on pace for the best home run output of his career, and it's also been encouraging to see his walk rate improve, albeit over a small sample size. Defensively, the 29-year-old is still adapting to third base, where he hadn't previously played since 2024. He has 0 OAA and 0 FRV at the hot corner, but he has already made an error. In most fantasy leagues, Donovan has eligibility as a middle infielder and outfielder. He currently ranks #23 among second basemen in RotoBaller's latest fantasy baseball rankings.

Emerson Hancock Turns Heads in First Start of the Season on Sunday

Seattle Mariners right-hander Emerson Hancock had a special night on Sunday in Seattle in the series finale against the Cleveland Guardians at T-Mobile Park to earn his first victory of 2026. Hancock has never looked so good, throwing six scoreless and hitless innings while walking just one and striking out a career-high nine. If the 26-year-old keeps pitching anywhere near this level going forward, it will be impossible for Seattle to kick him out of the starting rotation when right-hander Bryce Miller (oblique) is ready to return from the injured list. It's unclear exactly how long he'll stick in the M's rotation, but he'll definitely be a popular matchup-based streamer in his second scheduled start of the year next week against the division-rival Los Angeles Angels. Hancock has been mediocre at the big-league level the last three years, going 8-9 with a 4.81 ERA, 1.36 WHIP, 15.6% strikeout rate, and 7.6% walk rate in 162 2/3 innings. He's going to need to keep it up to be considered more than just a swingman in Seattle. Fantasy managers will want to keep a close eye on Hancock's progression.

Dominic Canzone Could Be a Worth a Deep-League Roster Spot in 2026

Seattle Mariners outfielder Dominic Canzone is off to a hot start to the 2026 season, hitting two home runs in eight plate appearances across the team's first three games of the season. As expected, the lefty-hitting Canzone was out of the starting lineup for Seattle's matchup against Cleveland Guardians' left-handed starter Joey Cantillo on Sunday. Still, Canzone looks like the Mariners primary designated hitter against right-handed starting pitchers. The 28-year-old excelled against right-handed pitching in 2025, slashing .308/.355/.524 with 10 home runs and 28 RBI in 201 plate appearances. Canzone could be a cheap source of power for fantasy managers to target on the waiver wire heading into the second week of the 2026 season.

J.P. Crawford Could Return From Shoulder Injury Soon

Seattle Mariners shortstop J.P. Crawford (shoulder) went through a light workout under the eye of infield coach Perry Hill and the team's athletic training staff before the game on Saturday against the Cleveland Guardians, according to Daniel Kramer of MLB.com. Crawford is scheduled to remain with the team through the weekend, and if all goes well, he'll begin a minor-league rehab assignment. His rehab assignment would likely come at Triple-A Tacoma. Crawford will likely be back from the 10-day injured list during the team's road trip, which begins on Friday and runs through Anaheim and Arlington. The 31-year-old received a cortisone shot for his ailing right shoulder last week for an injury that has been bothering him from early on in spring training. He's expected to go through a more vigorous workout on Sunday. Crawford only played in seven Cactus League games, but he's been receiving at-bats in minor-league games in camp for over a week. He should be ready to hit the ground running next weekend, barring a setback, but Crawford doesn't offer a ton of fantasy upside with very modest power and speed abilities in a pitcher-friendly home ballpark.

Rob Refsnyder Batting Leadoff for Mariners on Saturday

Seattle Mariners outfielder Rob Refsnyder is serving as the team's designated hitter and will bat in the leadoff spot on Saturday against the Cleveland Guardians and left-hander Joey Cantillo at T-Mobile Park, according to MLB.com. Refsnyder is known as a lefty killer in his career, and he's the only Mariners player who has faced Cantillo in his career, going 1-for-3 against him. It's Refsnyder's first action of the 2026 season for Seattle after spending the last four years with the Boston Red Sox. The 35-year-old veteran South Korean native is a career .255/.343/.387 hitter with 33 home runs, 154 RBI, and 22 stolen bases in his 10 big-league seasons. Against southpaws, though, Refsnyder has hit .281/.383/.443 with an .826 slash line, and 22 of his 33 career home runs in 791 plate appearances. In comparison, he has just a .633 OPS against right-handers. Similar to what his role was like in Boston, Refsnyder will enter Seattle's lineup as an outfielder or DH against lefties in 2026. With Refsnyder at leadoff, third baseman Brendan Donovan will move down to the six-hole on Saturday.

Dominic Canzone a Top Pickup After Two-Homer Game

Seattle Mariners outfielder Dominic Canzone came ready to play on Opening Day. He went 2-for-4 with a pair of solo home runs during Thursday's loss to the Cleveland Guardians. Canzone took right-hander Tanner Bibee deep in the second inning and blasted a 444-foot homer off Shawn Armstrong in the seventh inning. He started at designated hitter on Thursday, but Canzone figures to see playing time in the outfield as well. The 28-year-old slashed .300/.358/.481 with 11 home runs and 32 RBI across 82 games last season. His hot start to the season makes him worth snagging off waivers right now.

Does Cole Young Have Breakout Potential After Impressive Spring?

Seattle Mariners second baseman Cole Young made his MLB debut in 2025, hitting .211/.302/.305 with four home runs, 24 RBI, 24 runs scored, and one stolen base across 257 plate appearances. While Young's numbers at the plate amounted to well below-average production, it's important to remember that 2025 was just his age-21 season. Entering 2026, Young projects as Seattle's everyday second baseman and should have a second chance to establish himself as an everyday big-leaguer. Young put together an impressive performance in the Cactus League this spring, hitting .281/.349/.667 with six home runs and three stolen bases across 63 plate appearances. While Young recorded just one steal in the majors in 2025, he showcased more speed in his minor league career with back-to-back 20-plus steal seasons in 2023 and 2024. If he can take a step forward across the board with another year of development in 2026, Young could be a sleeper second base option off the waiver wire for deep-league fantasy managers.

Luis Castillo Set to Start Fifth Game of the Season

Seattle Mariners right-hander Luis Castillo will make his first start of the 2026 season in the team's fifth game on Monday, March 30, against the New York Yankees at T-Mobile Park, according to Adam Jude of The Seattle Times. Fantasy managers shouldn't read anything into the fact that Castillo will start the fifth game of the regular season after he pitched in the team's Cactus League finale on Monday. The 33-year-old veteran will have a difficult matchup to kick things off, though, after struggling in spring training. Castillo allowed 14 runs (13 earned) on 23 hits (five home runs) while walking four and striking out 13 in 15 innings pitched over five starts. Spring statistics should always be taken with a grain of salt. Castillo has had ERAs under 4.00 in three straight seasons and has also made at least 30 starts for fantasy managers over that span. He's no ace, but Castillo's fantasy floor is pretty high, especially when starting at pitcher-friendly T-Mobile Park.

Bryce Miller • SP • Mariners

Bryce Miller Placed on 15-Day Injured List With Oblique Strain

The Seattle Mariners placed right-hander Bryce Miller (oblique) on the 15-day injured list on Wednesday with a left-oblique strain, according to MLB.com's Daniel Kramer. Miller only made one appearance during spring training after injuring his oblique late last month. The good news, though, is that the 27-year-old hasn't had any setbacks after throwing a couple of bullpen sessions in camp. Miller still needs a couple of weeks to build his arm back up, but barring a setback, he figures to rejoin Seattle's starting rotation before the end of April. In the meantime, Emerson Hancock will take Miller's spot in the team's rotation. The former fourth-round pick of the Mariners in 2021 out of Texas A&M went 12-8 with a 2.94 ERA, 0.98 WHIP, and 171:45 K:BB in 31 starts in his second big-league season before dealing with injuries and posting a 5.68 ERA and 1.41 WHIP in just 18 starts in 2025 due to injuries. Miller is pitching with a bone spur in his right elbow as well, making him more of a risk in 2026, but he's still a worthwhile IL stash for his upside in mixed fantasy leagues.

J.P. Crawford Starting Season on 10-Day Injured List

The Seattle Mariners placed shortstop J.P. Crawford (shoulder) on the 10-day injured list on Wednesday with right-shoulder inflammation, according to Daniel Kramer of MLB.com. Crawford received a cortisone injection last week for a shoulder injury that he's dealt with since the start of spring training in February. He managed to play in seven Cactus League games, though, going 2-for-16 (.125) with three RBI and a stolen base. The good news for the M's is that they could have their starting shortstop back when he's eligible to come off the IL on Wednesday, April 1. Until then, Leo Rivas will have added value in AL-only leagues as middle-infield depth as the starter at the 6 for Seattle. Crawford's injury isn't serious, but it's another knock on the former first-rounder and his limited fantasy upside. He had double-digit home runs (12) for just the second time in his nine-year MLB career in 2025, and he's never had double-digit stolen bases in 930 career games.

Lazaro Montes • RF • Mariners

Lazaro Montes Will Begin 2026 at Double-A

Seattle Mariners outfield prospect Lazaro Montes will begin the season at Double-A Arkansas, per Francys Romero of BeisbolFR.com. The Mariners' fourth-ranked prospect played nearly half of his games in 2025 there after starting the season at High-A. The powerful left-handed hitter blasted 32 home runs in '25, 14 of which came in 64 games at Double-A. With his big-time power comes a lot of swing-and-miss, though, as the 6-foot-5 slugger registered a 30.5 percent strikeout rate during his time with Arkansas (career 27.1 percent K%). It was somewhat offset by a strong 12.4 percent walk rate (career 15.2 percent BB%), but with just a .213 AVG at Double-A, the team would surely like to see the Cuban take a step forward in 2026 before sending him on to Triple-A. With a strong showing at both levels, there's a chance MLB's No. 43 overall prospect makes a late-season debut, but 2027 is when he'll likely begin making an impact for fantasy. Redraft managers should keep an eye on his progress, as the power is for real, and if he gets the call in September, he could provide a home-run boost for teams in need.

Mitch Garver Wins Backup Catching Job in Seattle

Seattle Mariners catcher Mitch Garver has made the Opening Day roster, according to Shannon Drayer of Seattle Sports. He won the backup catcher job over Andrew Knizner, who is expected to be designated for assignment. Garver, 35, enters his third season with the Mariners and his 10th in the majors. He slashed .209/.297/.343 with 86 wRC+ at the plate last year, and he hasn't posted positive defensive fWAR since 2021 (2.0). Depending on how the Mariners manage Cal Raleigh's workload, we could see Garver come close to matching his 2025 total of 290 plate appearances. Raleigh played roughly three-quarters of last season behind the dish, with the remaining one-quarter comprising days off or designated hitter appearances.

Colt Emerson Gets Reassigned to Minors Camp

Seattle Mariners infielder Colt Emerson has been reassigned to minor league camp on Saturday. It's not a huge surprise that Emerson won't make the Opening Day roster. The 20-year-old didn't have a great shot with Cole Young playing extremely well right now. Across 18 games, Emerson slashed .268/.340/.488 with two home runs and eight RBI during his time in Spring Training. The Mariners feel that the former first-round pick still needs some time to develop in the minor leagues. He earned a promotion to Triple-A Tacoma last season, so he figures to begin the year there. It wouldn't be shocking to see Emerson playing in Seattle at some point during the 2026 season.

Cal Raleigh Remains the Clear No. 1 Catcher Across All Formats

Seattle Mariners catcher Cal Raleigh had one of the all-time great offensive seasons by a backstop in 2025, slashing .247/.359/.589 with 60 home runs, 125 RBI, 114 runs scored, and 14 stolen bases across 705 plate appearances. With a career 15.4% barrel rate and 153 career home runs to his name across 623 total MLB games, Raleigh's ability to hit for power is not up for debate. He also lowered his strikeout rate to a career-best 26.7% in 2025, which could help his batting average in 2026 stay closer to his 2025 mark than his career average of .226. While Seattle will deploy Raleigh at designated hitter on days when he needs a break from catching, it may be difficult for him to reach 700 plate appearances for the second straight year. However, even if his counting stats regress across the board, Raleigh still projects as the number one catcher in fantasy baseball by a significant margin. Managers will have to pay a steep price in drafts to get Raleigh on their teams, but his upside relative to his positional peers may make him worth it.

Rob Refsnyder • RF • Mariners

Rob Refsnyder Exits Early During Thursday's Game

Seattle Mariners outfielder Rob Refsnyder (elbow) was forced to make an early exit from Thursday's Cactus League matchup against the Athletics. Refsnyder was forced to exit in the sixth inning after getting hit by a pitch on the left elbow. The organization hasn't given an update on his status, so fantasy managers should consider him day-to-day for now. The 34-year-old signed a one-year, $6.25 million deal with the Mariners over the offseason. He crushes left-handed pitching, so the expectation is that he'll be a platoon bat in the outfield and at designated hitter. His struggles against right-handed pitching make him difficult to trust as a long-term option and more of a streaming choice.

Logan Gilbert Named Mariners Opening Day Starter

The Seattle Mariners announced on Thursday that right-hander Logan Gilbert will make the start on Opening Day next Thursday, March 26, against the Cleveland Guardians at T-Mobile Park in Seattle. It will be Gilbert's second straight Opening Day assignment. The 28-year-old went 6-6 with a 3.44 ERA (3.35 FIP) and 1.03 WHIP with 173 strikeouts and 31 walks in 131 innings over his 25 starts in 2025 in his fifth year in the big leagues with the M's. He was a first-time All-Star in 2024, when he had a nice 3.23 ERA, league-leading 0.89 WHIP, and a career-high 220 strikeouts in a league-high 208 2/3 innings over 33 starts. Gilbert's 2025 season might have looked much better had he not dealt with a flexor strain in his right elbow that caused him to miss over a month of action. Despite dealing with arm issues last year, Gilbert had a career-high 32.3% strikeout rate, and he has one of the highest floors of any high-end fantasy starter. RotoBaller has Gilbert ranked as the No. 6 fantasy starting pitcher in 2026.

J.P. Crawford Receives Injection, Uncertain for Opening Day

Seattle Mariners shortstop J.P. Crawford (shoulder) received an injection in his shoulder on Wednesday and will be shut down for a few days, according to Ryan Divish of The Seattle Times. Manager Dan Wilson is unsure if Crawford will be ready for Opening Day in late March. The 31-year-old has been dealing with a cranky shoulder for most of spring training, which is why he has only appeared in seven Cactus League games. Crawford's injury increases the likelihood that infield prospect Colt Emerson makes the team's Opening Day roster. Leo Rivas will be another option for Seattle at the 6 if Crawford is not ready for the start of the 2026 regular season. Crawford already wasn't much to look at in terms of fantasy baseball value with modest power and speed abilities, and now he's even less attractive with the possibility that he will open the year on the injured list. In his ninth MLB season in 2025, he hit .265/.352/.370/ with a .722 OPS, 12 homers, 58 RBI, 69 runs scored, and eight steals in 157 regular-season games.

Cole Young Flashing Power in Spring Games

Seattle Mariners infielder Cole Young has begun to flash high-end power in spring training and appears to be the favorite to be the team's Opening Day second baseman. Across 15 spring games, Young has held a .273/.343/.614 slash line with four home runs and three stolen bases. Young is in competition with fellow young infielder Colt Emerson, who is considered the team's top-ranked prospect. While Young does have MLB experience, which gives him a slight edge, Emerson has also enjoyed a strong showing in camp. Last summer, Young made his MLB debut and held a .211/.302/.305 line with a low .607 OPS over a 77-game stint. While he only had four home runs and stole one base last season, Young appears to be taking the next step in his development in camp. If he earns the starting second base job, he is worth a late-round flyer in deeper formats as a middle infielder with upside.

Bryce Miller • SP • Mariners

Bryce Miller Throws Full Bullpen Session

Seattle Mariners right-hander Bryce Miller (oblique), who has been out since he cut his bullpen session short on March 11 due to a left-oblique injury, threw a full bullpen session in camp on Tuesday of around 30 pitches without any restrictions, according to MLB.com's Manny Randhawa. Miller has made only one Cactus League start this year, pitching 1 1/3 scoreless innings. The 27-year-old had a 2.94 ERA in 31 starts in a breakout 2024 season, but he made only 18 starts in 2025 due to injuries and finished with an ugly 5.68 ERA. His bullpen session was good news on Tuesday, but Miller isn't going to be ready for the start of the regular season in less than two weeks. Either Emerson Hancock or Cooper Criswell will take Miller's spot in the starting rotation to begin the 2026 campaign. Miller has bounce-back potential, but more injuries this spring have nearly pushed him outside of the top-100 starting-pitcher rankings at RotoBaller.
