Davis went 1-for-1 with a three-run homer, two walks and a second run scored in Sunday's Cactus League matchup versus the Reds.
Davis capped a six-run ninth inning with his three-run shot off right-hander Irvin Machuca, extending Seattle's lead to 14-8. It was a strong day at the plate overall for the 26-year-old Davis, who reached base safely in all three of his at-bats. Still, the one-time top prospect is a long shot to make the Mariners' Opening Day roster, after joining the team as a non-roster invitee in December. However, Davis had a solid 2025 campaign with Triple-A Scranton-Wilkes Barre, posting a .900 OPS with 12 homers across 36 games.

Mariners' Miles Mastrobuoni: Smacks grand slam in spring debut
Rotowire
Mastrobuoni went 2-for-2 with a double and a grand slam in Saturday's Cactus League matchup with the Giants.
It was a strong start to the spring for Mastrobuoni, who got the start in left field Saturday. He put the Mariners ahead early with his first-inning grand slam off Hayden Birdsong. Mastrobuoni, who hit just one home run while posting a .620 OPS in 175 plate appearances last season, has a shot to make Seattle's Opening Day roster as a bench option thanks to his positional versatility.

Mariners' Matt Brash: Issues following tooth removal
Rotowire
Brash said Sunday that he's been slowed down in spring training after having a tooth removed last week, Ryan Divish of The Seattle Times reports.
After spending a few days at home recovering from the procedure, Brash checked back in with the training staff Saturday and "looked to be very uncomfortable," per Divish. The issue doesn't sound like anything that could affect Brash's Opening Day availability, but his spring debut will be on hold until he's feeling better.

Mariners' Michael Arroyo: Homers in spring opener
Rotowire
Arroyo started at second base and went 2-for-2 with a two-run homer and a double in Friday's Cactus League opener against the Padres.
Arroyo drove an opposite-field homer off a two-strike pitch from Jagger Haynes in the second inning, giving the Mariners an early 2-0 lead. It was reported earlier in the offseason that Arroyo would transition to the outfield, though he ultimately got the start at second base in Seattle's spring opener. While it remains to be seen where Arroyo will fit in the field long term, his major-league future will ultimately come down to his bat. Arroyo slashed .262/.401/.433 with 17 home runs across 556 plate appearances between High-A and Double-A last year. He should see regular playing time early in Cactus League play before reporting to Team Colombia for the World Baseball Classic.

Mariners' Mitch Garver: Inks minor-league deal with Seattle
Rotowire
The Mariners signed Garver to a minor-league contract Wednesday, Jeff Passan of ESPN.com reports.
Garver spent the last two seasons with the Mariners serving as the team's backup catcher to Cal Raleigh. Garver will get a chance to reprise that role for the 2026 campaign, and he'll face competition from Jhonny Pereda and Andrew Knizner in spring training. Garver appeared in 87 regular-season games for Seattle in 2025 and slashed .209/.297/.343 with three steals, nine home runs and 30 RBI across 290 plate appearances.

Mariners' Logan Evans: Lands on 60-day injured list
Rotowire
The Mariners placed Evans (elbow) on the 60-day injured list Monday.
The transaction clears a spot on the 40-man roster for the arrival of Josh Simpson, who was acquired via trade with the Marlins on Monday. Evans will miss the entire 2026 season after undergoing UCL reconstruction surgery with an internal brace in January.

Mariners' Josh Simpson: Shipped to Seattle
Rotowire
The Mariners acquired Simpson from the Marlins on Monday in exchange for cash considerations.
Simpson reached the big leagues for the first time in 2025 but was unable to work his way into a high-leverage role with Miami after submitting a 7.34 ERA and 1.83 WHIP in 30.2 innings. The southpaw yielded five home runs over 31 appearances and walked 14.6 percent of the batters he faced, but he generated ground balls at a high rate (59.6 percent) and struck out hitters at a decent clip (23.8 percent). Seattle recognized enough potential in Simpson to bring him aboard as an extra left-handed option out of the bullpen and opened up a 40-man roster spot for him by placing Logan Evans (elbow) on the 60-day injured list.

Mariners' Bryce Miller: Elbow feeling 100 percent
Rotowire
Miller said Monday that he hasn't dealt with any discomfort in his right elbow this offseason and the elbow "feels 100 percent" early in spring training, Daniel Kramer of MLB.com reports.
Miller had two stints on the injured list last season due to a bone spur in his right elbow, but after a consultation this offseason with Dr. Keith Meister, the 27-year-old was able to avoid surgery. Though the elbow could give him trouble again at some point during the upcoming season, Miller looks to be in a good spot on the health front for the time being. He'll be looking to bounce back in 2026 after collecting a 5.68 ERA and 74:34 K:BB over 90.1 innings during the regular season in 2025.
Mariners' Kade Anderson: Impressing early in spring
Rotowire
Anderson has impressed early in spring training and is expected to advance quickly through the Mariners system, Ryan Divish of The Seattle Times reports.
Anderson has yet to make his professional debut since being selected with the No. 3 overall pick in the 2025 First-Year Player Draft, but the left-hander is already receiving rave reviews following his performance Sunday during a live batting practice session against some Mariners regulars. Anderson is likely to begin the upcoming season with High-A Everett, though he's not expected to "spend a heck of a lot of time in the high minors," according to Jerry Dipoto, the Mariners' president of baseball operations. Seattle's rotation is one of the league's best, and while Anderson still has a lot to prove, he could have an outside chance at making his MLB debut at some point in 2026.

Mariners' Ryan Sloan: Back in action after eye procedure
Rotowire
Sloan (eye) threw a live batting practice session Sunday, Daniel Kramer of MLB.com reports.
Despite having yet to pitch above the High-A level, Sloan didn't look out of place while facing off against some of the Mariners' top hitters in Cal Raleigh, Randy Arozarena and Josh Naylor during the BP session. According to Ryan Divish of The Seattle Times, the 20-year-old righty sported a four-seamer that hit 99 miles per hour and a two-seamer that reached 98 mph. Sloan missed the final month of the 2025 campaign after undergoing a procedure on his eye, but he's seemingly free of restrictions heading into 2026 and could establish himself as one of the game's top pitching prospects if health prevails this season.
Bliss (knee/biceps) went through a full infield workout and was scheduled to hit Thursday in Mariners camp, Daniel Kramer of MLB.com reports.
Bliss missed virtually all of the 2025 season, first due to April biceps surgery and later a September meniscus tear. However, it would seem he has been cleared to participate fully at the beginning of spring training. The 26-year-old is theoretically in the mix for the second-base job, but it's likely he will begin the season at Triple-A Tacoma as he knocks off some rust.

Mariners' Jhonathan Diaz: Invited to spring training
Rotowire
Diaz was added to the Mariners' spring training roster as a non-roster invitee.
Diaz was designated for assignment and outrighted to Triple-A in January, when the Mariners acquired Cooper Criswell. The left-hander will likely be a depth option for Seattle's bullpen this season, although he isn't guaranteed a spot on the Opening Day roster. He made just one big-league appearance in 2025.
Joe agreed to a minor-league contract with the Mariners on Tuesday that includes an invite to big-league spring training.
Joe split last season between San Diego and Cincinnati, posting a .186/.262/.243 slash line in 42 games before being outrighted off the Reds' 40-man roster in August. The 33-year-old offers some defensive versatility but is likely a longshot to make Seattle's Opening Day roster.
The Mariners could give Emerson more seasoning at Triple-A Tacoma following the acquisition of Brendan Donovan, Daniel Kramer of MLB.com reports.
Emerson will compete with Cole Young for a spot in the Mariners' lineup, but Young is considered the heavy favorite for the second-base job entering camp. The 20-year-old Emerson reached Tacoma in 2025, finishing with a .285/.383/.458 batting line with 16 home runs and 14 stolen bases over 130 games covering three levels of the minors. He should get an opportunity at the big-league level at some point during the 2026 campaign.
