J.P. Crawford Back at Shortstop on Monday

Seattle Mariners shortstop J.P. Crawford (shoulder) is back in the Cactus League lineup on Monday against the Arizona Diamondbacks, as expected, after a brief hiatus this spring due to shoulder pain, according to Ryan Divish of The Seattle Times. Crawford is at shortstop and is batting fifth for the M's. He said he has played through worse during the regular season, but since it's spring training, the team decided to have him rest his shoulder. Barring a setback, Crawford should be just fine for the start of the 2026 regular season in late March. Monday's game is Crawford's first start at shortstop since Feb. 20. The 31-year-old former 16th overall pick by the Philadelphia Phillies in 2013 hit .265/.352/.370 with a .722 OPS, 12 home runs, 58 RBI, 69 runs scored, and a career-high eight steals in 157 games last year in his ninth year in the league. With limited power and speed -- he has only reached double-digit homers twice in his career and has never stolen double-digit bases -- Crawford has limited fantasy upside. He's ranked as RotoBaller's No. 39 fantasy shortstop.

Bryce Miller to Throw a Bullpen on Sunday

Seattle Mariners right-hander Bryce Miller (oblique, side) will go through a touch-and-feel bullpen session in camp on Sunday, according to Daniel Kramer of MLB.com. It will be Miller's first time on a mound since he received a platelet-rich plasma injection last weekend. He has been throwing off flat ground the last few days. The 27-year-old can't afford any other setbacks if he wants to be ready for Opening Day later this month. Miller's 2025 season was derailed by elbow issues that landed him on the injured list two separate times. The former fourth-rounder in 2021 out of Texas A&M never recovered, going 4-6 with a career-worst 5.68 ERA (5.17 FIP) and 1.41 WHIP with 74 strikeouts and 34 walks in 90 1/3 innings pitched over a career-low 18 starts. There's bounce-back potential for Miller if he's healthy in 2026, but in addition to his oblique/side issue, he could eventually need a procedure for a bone spur in his elbow.

Bryce Miller Shut Down for Five Days With Side Soreness

Seattle Mariners right-hander Bryce Miller (side) has been battling soreness in his left side in camp, and an MRI exam showed inflammation, according to Shannon Drayer. Miller, who has dealt with this same issue in the past, had a platelet-rich plasma injection and is being shut down for five days. Drayer adds that it's "very precautionary." If it were the regular season, Miller "probably wouldn't have reported the soreness." The 27-year-old reported soreness after his Cactus League outing on Thursday against the Cleveland Guardians. As long as Miller doesn't have any further setbacks with his side, he still has a chance to be ready for Opening Day in late March. Miller went on the injured list two separate times in 2025 due to elbow issues and made a career-low 18 starts, posting a career-worst 5.68 ERA, 1.41 WHIP, and 74:34 K:BB in 90 1/3 innings. It's possible that he could eventually need surgery for the bone spur in his right elbow, making Miller a risk/reward late-round consideration in 2026 drafts for rotation depth.

Luis Castillo May Be Showing Signs of Decline Heading into 2026

Seattle Mariners starting pitcher Luis Castillo has long been one of MLB's most durable and reliable right-handers. The 33-year-old started to show some signs of decline in 2025, but still posted solid numbers overall. Across 180 2/3 innings (32 starts), Castillo posted an 11-8 record with a 3.54 ERA, 1.18 WHIP, and 162 strikeouts. Castillo's 21.7% strikeout rate was by far the lowest of his career, and he also allowed the highest barrel (10.4%) and hard-hit (46.4%) of his nine-year MLB tenure. Castillo has the benefit of making his home starts in one of the game's most pitcher-friendly environments in Seattle. In 2025, he posted a 2.60 ERA and 0.97 WHIP across 100 1/3 innings at home compared to a 4.71 ERA and 1.46 WHIP in 80 1/3 innings on the road. Castillo's days of being a high-end fantasy starting pitcher are likely behind him, but he's still a savvy veteran who should be usable in all of his home starts. He checks in as RotoBaller's SP49 heading into 2026.

Colt Emerson Heating Up at Spring Training

Seattle Mariners top prospect Colt Emerson has begun to find his footing in spring training and is making a strong case to crack the Opening Day roster. On Tuesday, Emerson went 2-for-3 with two RBI and a run. In his next contest on Thursday, Emerson stayed hot at the dish, going 2-for-3 once again. He has now gone 4-for-11 through his first five contests this spring. Last summer, the 20-year-old spent most of his time at High-A and Double-A but did earn a short stint at Triple-A, which has opened the door for an early 2026 MLB debut. Across 124 games shared between High-A and Double-A, Emerson posted a .280/.380/.444 line with 14 long balls and 14 stolen bases. The No. 9-ranked prospect on MLB.com remains a top name to watch in camp as he would hold high-end sleeper value if he can earn a spot on the Opening Day roster.

J.P. Crawford has Minor Shoulder Injury

Seattle Mariners shortstop J.P. Crawford (shoulder) is dealing with a minor shoulder issue that has kept him from playing in a Cactus League game early in spring training, manager Dan Wilson told Daniel Kramer of MLB.com. Kramer writes that the Mariners' concern level "appears low," and Crawford dealt with something similar last spring. The 31-year-old veteran is expected to make his spring debut at some point next week, so this isn't an injury that should affect his availability for the start of the 2026 regular season. Crawford's injury will open up more opportunities early on for top prospect Colt Emerson, who is battling for a spot on the team's Opening Day roster. Although Crawford didn't really stand out in any one area, he bounced back in 2025 to slash .265/.352/.370 with a .722 OPS, 12 home runs, 58 RBI, 69 runs scored, and a career-high eight steals in 157 regular-season games. Plate discipline is Crawford's strength, but his lack of power and speed makes him mostly middle-infield depth in deep-mixed fantasy leagues.

Can Dominic Canzone Build on 2025 Breakout?

Seattle Mariners outfielder Dominic Canzone broke out in 2025, hitting .300/.358/.481 with 11 home runs, 32 RBI, 30 runs scored, and three stolen bases across 268 plate appearances. The 28-year-old cut his strikeout rate from 28.2% in 2024 to 22% in 2025 while still posting an excellent 14.5% barrel rate. The lefty-swinging Canzone owns a career .756 OPS against right-handed pitching compared to just a .607 OPS against southpaws, so he may be limited to a large-side platoon role in Seattle. Canzone seems likely to see most of his at-bats in 2026 at designated hitter, but he could also get in the mix in right field if Mariners outfielder Victor Robles struggles or misses time due to injury. Given Canzone's likely playing time ceiling and his lack of speed (five career stolen bases), his fantasy upside is limited. However, Canzone has sleeper potential at his current average draft position of pick 336 if he can lock down a spot in the starting lineup whenever Seattle faces a right-handed starting pitcher.

Matt Brash Not Feeling Great After Tooth Removal

Seattle Mariners right-handed reliever Matt Brash (mouth) played catch briefly in camp on Sunday but "still isn't feeling great," according to Ryan Divish of The Seattle Times. Brash had issues with the tooth abstraction that led to more dental work and discomfort, which is why he's been slow to return in spring training. The Mariners still have plenty of time to get him ready for Opening Day in late March, though, since he will not take part in this year's World Baseball Classic. The 27-year-old missed all of the 2024 campaign after having elbow reconstruction, but he returned to a setup role last year and was solid, recording a 2.47 ERA (3.05 FIP), 1.25 WHIP, four saves, 58 strikeouts, and 18 walks in 47 1/3 frames. Brash induced more ground balls by using his slider and sinker more, and he'll return to the eighth-inning setup role for Seattle. Brash is primarily useful in holds leagues, but he has the stuff to close out games if needed if Andres Munoz were to miss time due to an injury.

Logan Gilbert to Make Spring Debut on Monday

Seattle Mariners starting pitcher Logan Gilbert is scheduled to make his Spring Training debut versus the Los Angeles Dodgers on Monday. It's still early in camp, which means Gilbert will likely only face a handful of batters. Reliever Jose A. Ferrer is also scheduled to pitch on Monday, but the rest of the arms are unknown at the moment. Gilbert posted a strong 2025 campaign but was limited to 25 starts due to injuries. During that time, Gilbert posted a 3.44 ERA, 1.03 WHIP, and a 173/31 K/BB ratio across 131.0 innings of work. He is one of the most consistent arms in the Mariners' rotation. The 28-year-old should be a trustworthy fantasy option heading into the 2026 campaign.

Bryce Miller Looking to "Go Even Further" in 2026

The Seattle Times' Ryan Divish reports that Seattle Mariners right-hander Bryce Miller (elbow) has no pain in his right elbow and has two improved breaking pitches this spring. Miller is "excited to pitch a full season" and to help the Mariners "go even further" in 2026. The 27-year-old did not need surgery to have bone spurs in his elbow removed despite going on the injured list two separate times last year due to elbow problems. It's great news, but Miller goes into the 2026 campaign with a little more risk. Miller struggled in his third year in the big leagues, most likely due to his elbow issues, going 4-6 with a career-worst 5.68 ERA (5.17 FIP) and 1.41 WHIP with 74 strikeouts and 34 walks in 90 1/3 innings over 18 starts. It was promising that he had a 2.51 ERA in the playoffs in a small sample size, as well as the fact that he's feeling 100% in camp. Miller will slowly start to rise up draft boards as a bounce-back candidate if he can avoid further elbow injuries.

Bryce Miller Says his "Elbow Feels 100 Percent"

Seattle Mariners right-hander Bryce Miller (elbow) said he didn't experience any discomfort in the offseason, and his pitching "elbow feels 100%," according to Daniel Kramer of MLB.com. After extended consultation with Dr. Keith Meister, it was decided that Miller would not need a procedure to remove the loose bone spurs in his right elbow. The 27-year-old was limited to a career-low 18 starts in 2025 due to two separate stints on the injured list with elbow injuries, and he finished the regular season with a 4-6 record, career-worst 5.68 ERA (5.17 FIP), and 1.41 WHIP with 74 strikeouts and 34 walks in 90 1/3 innings pitched. Miller's elbow issues will make fantasy managers think twice about rostering him in 2026, but if he can stay healthy, a bounce-back should be in store. He broke out in 2024 with a 2.94 ERA, 0.98 WHIP, and 171 K's in 31 starts, and he looked good in the postseason with a 2.51 ERA over 14 1/3 innings. RotoBaller has Miller ranked as the No. 67 fantasy starting pitcher.

Bryan Woo Turns Down WBC as he Eyes Larger 2026 Workload

Seattle Mariners right-hander Bryan Woo said he turned down an invitation to pitch for Team USA in this year's World Baseball Classic as he looks to reach the 200-inning mark in 2026, according to Daniel Kramer of MLB.com. The former sixth-round pick out of Cal Poly in 2021 had a breakout 2025 campaign with Seattle, going 15-7 with a 2.94 ERA (3.47 FIP) and 0.93 WHIP with a career-high 198 strikeouts and 36 walks in 186 2/3 innings pitched over 30 starts. It was nice to see Woo make 30 starts after some of his early career injury woes, and even though he's healthy this spring, the Mariners might ease him into Cactus League action. Woo led Seattle's rotation in innings, K's, WHIP, and ERA while posting a 128 ERA+, putting him in the running to start on Opening Day in 2026. He's a starting pitcher on the rise in a very favorable pitching environment at T-Mobile Park. Consider him a top-15 fantasy starting pitcher.

Colt Emerson in Consideration to Break Camp with MLB Roster

Seattle Mariners top prospect Colt Emerson is in serious consideration to break camp with the MLB roster. According to Daniel Kramer of MLB.com, the team's President of Baseball Operations, Jerry Dipoto, noted that it's "not out of the question" that the top shortstop prospect begins the season in Seattle. According to MLB.com, Emerson, the former 22nd overall pick from the 2023 MLB Draft, is viewed as the team's No. 1-ranked prospect and the overall No. 9 prospect in the sport. Last summer, the 20-year-old spent most of his time with High-A and Double-A and performed at an elite level. With High-A, Emerson held a .281/.388/.453 line with 11 long balls and six stolen bases. Through 40 games shared between Double-A and Triple-A, Emerson posted a .293/.373/.470 line. He is a top name to watch in camp as he could be worthy of a late-round selection.

Ryan Bliss • 2B • Mariners

Ryan Bliss Back in Action at Spring Training

Seattle Mariners infielder Ryan Bliss (knee, biceps) was part of a full infield workout at second base at spring training on Thursday, according to Daniel Kramer of MLB.com. It's a promising sign for Bliss after he missed most of last year with significant meniscus and biceps injuries. The 26-year-old only appeared in 11 games at the big-league level in 2025 with Seattle, going 7-for-35 (.200) with a homer, three RBI, and two stolen bases. Bliss had surgery on his biceps last April and then tore his meniscus in September. The former second-round pick by the Arizona Diamondbacks in 2021 out of Auburn hit just .222/.290/.397 with a .687 OPS, two home runs, nine RBI, 10 runs scored, and five stolen bases in 71 games for the M's in his rookie campaign in 2024. Bliss will be competing at the keystone this spring, but in all likelihood, he'll begin the year as infield depth at Triple-A Tacoma.

Colt Emerson to Begin the Year in the Minors?

MLB.com's Daniel Kramer writes that Seattle Mariners infield prospect Colt Emerson, who is MLB Pipeline's No. 9 overall prospect, "could still need seasoning by Opening Day." Emerson, 20, will be competing with fellow infield prospect Cole Young at second base in spring training, but Young is seen as the favorite after getting his first taste of the majors in a 77-game stint in 2025. Kramer believes that Young has as much upside as any position-player prospect in Seattle since outfielder Julio Rodriguez, but the recent acquisition of utility man Brendan Donovan should give the Mariners more time to let Emerson develop. Even if Emerson ends up on the Opening Day roster, Seattle is expected to avoid using him against tough left-handed pitchers. The former first-rounder reached Triple-A last year and hit an impressive .285/.383/.458 with 16 homers and 14 steals in 130 games over three minor-league levels. Emerson's power/speed upside makes him stash-worthy in 2026 fantasy leagues, even if he starts at Tacoma.

Cole Young • 2B • Mariners

Cole Young Appears to be the Favorite to Start at Second Base

MLB.com's Daniel Kramer writes that Seattle Mariners infield prospect Cole Young has the "leg up to make the team and would have to struggle mightily to lose his grip on the second-base job." The Mariners are "bullish" on the 22-year-old being their second baseman of the future now that Jorge Polanco is out of town. Young bats left-handed, and there's a likelihood that the Mariners avoid using him against the game's better left-handed pitchers. On those days, new utility man Brendan Donovan could shift to the keystone. Kramer has Young projected to hit eighth in Seattle's batting order against righties. The former 21st overall pick in 2022 struggled in his MLB debut in 2025, hitting .211/.302/.305 with a .607 OPS, four home runs, 24 RBI, and a 47:28 K:BB ratio in 77 games. There's not a ton of short-term upside for Young, and if he struggles, fellow infield prospect Colt Emerson could take playing time from him.

Brendan Donovan • 2B • Mariners

Brendan Donovan Expected to Mostly Play 3B in Seattle

MLB.com's Daniel Kramer writes that Seattle Mariners utility man Brendan Donovan, who was acquired from the St. Louis Cardinals earlier this week in a three-team trade, will play all over the field based on matchups, according to sources familiar with the club's thinking. The 2025 All-Star is expected to enter spring training as the primary third baseman, but it could change based on positional competitions, specifically among infielders Cole Young and Colt Emerson, Seattle's first-round picks in 2022 and 2023, respectively. Donovan's presence as an option all around the infield could benefit both Young and Emerson long term and take pressure off them to perform right away in 2026. Donovan, who had an .853 OPS against righties and a .614 OPS against lefties last year, won't be in a platoon. In addition to playing every day, Donovan will be the M's leadoff hitter. The 29-year-old rarely strikes out (13% K rate in 2025), but his lack of power and speed severely limit his fantasy appeal in mixed leagues.

Logan Gilbert Looking to Build on Effective 2025 Campaign

Seattle Mariners starting pitcher Logan Gilbert is coming off a strong 2025 season, during which he posted a 2.95 xFIP with 11.89 K/9 and 2.13 BB/9. Along the way, he tied for second among Mariners pitchers in fWAR. The biggest blemish against Gilbert last year was his susceptibility to loud contact, as he surrendered home runs at a 1.37 HR/9 clip while his ground ball rate dropped to 38.9%. Outside of a few minor concerns, Gilbert has established himself as one of the best MLB arms in terms of control and results. He also has a fascinating pitch mix headlined by the splitter, which earned a 144 Stuff+ grade by FanGraphs' model. Meanwhile, he sat in the mid-to-upper-90s with his fastball. Gilbert currently projects as the Mariners' #2 starter behind Bryan Woo, and he ranks at #6 in the latest RotoBaller fantasy baseball draft rankings.

Cal Raleigh • C • Mariners

Can Cal Raleigh Duplicate his Monster Season?

Seattle Mariners catcher Cal Raleigh had unprecedented success last year, breaking through for 60 home runs and 125 RBI. He's clearly the top bat available at a thin catcher position, and the fact that he's in the lineup almost every day, either behind the plate or at DH, makes him an even more valuable asset at one of the thinnest fantasy baseball positions. Raliegh played 159 games for the Mariners last year, hitting .247 with those 60 homers and a .392 wOBA while also adding in a sneaky 14 stolen bases. Big Dumper cut down on his strikeout rate and increased his barrel rate to a career-high 19.5%. He has at least 30 homers in three straight seasons and will be 29 when this season begins. There's likely to be some regression since no switch-hitting catcher has been so productive, but he was better than every other catcher by such a wide margin that he's still a great fantasy option for 2026. Barring injury, we should have a few more seasons of peak Raleigh, and he makes a lot of sense as an early target in most formats, where no other catcher comes close to matching his upside and production.

Andres Munoz a Top-Five Fantasy Closer After Another Dominant Season

Seattle Mariners right-handed closer Andres Munoz has established himself as a high-end closing option for fantasy managers after posting a 1.92 ERA (2.88 FIP), 0.99 WHIP, 60 saves, 160 strikeouts, and 54 walks in 121 2/3 innings for the Mariners in the last two seasons. The 27-year-old Mexican reliever had career highs in ERA (1.73) and saves (38) last year while also striking out 83 batters and posting a strong 1.03 WHIP in 62 1/3 frames. Munoz's 88.4% team save share was second-best among closers in 2025. He's no stranger to injuries, but Munoz has been an All-Star the last two years while staying healthy. His slider is one of the nastiest pitches in the league among relievers. For a Mariners team that should be in contention again in 2026. Munoz has high-end fantasy upside, although walks could be an issue. RotoBaller has him ranked as the No. 4 fantasy closer.
