Report: Seattle Mariners calling up No. 10 prospect Jonatan Clase
The Seattle Mariners are reportedly making a surprising call up after an injury to outfielder Dominic Canzone.
Seattle Mariners outfielder pays price for spectacular catch
ESPN baseball insider Kiley McDaniel said Sunday night on social media that the Mariners will bring up 21-year-old outfielder Jonatan Clase from Triple-A Tacoma.
Clase, the No. 10 prospect in the Mariners farm system per MLB.com, is best known for his blazing speed. He stole 79 bases on 94 attempts between Single-A Everett and Double-A Arkansas in 2023.
He’s off to a hot start with Triple-A Tacoma this season, owning a .311 average, .396 on-base percentage and .622 slugging percentage for a 1.018 OPS for the Rainiers. He has two home runs, four doubles, two triples and three steals on six attempts in 12 games.

Clase also impressed when given playing time in Cactus League play for the Mariners in spring training, hitting .321 with two doubles and three steals in 15 games.
Clase made his T-Mobile Park debut last year, representing the Mariners in their home ballpark in the MLB All-Star Futures Game, an annual prospect showcase that takes part on the Saturday of the league’s All-Star break.
A switch-hitter, the 5-foot-9, 150-pound Clase began his professional career after signing with the Mariners as an international free agent out of the Dominican Republic. He made his pro debut as a 17 year old in the Dominican Summer League in 2019.
Clase has mainly played center field in the minors, though he has appeared in left field three times for Tacoma this year.
The Mariners are expected to make a move ahead of Monday’s series opener at home against the Cincinnati Reds due to Canzone suffering an AC joint sprain (shoulder/clavicle) when he collided with the wall in left field on a catch in the first inning of Seattle’s 3-2 loss Sunday to the Chicago Cubs. Manager Scott Servais said after Sunday’s game that he believed Canzone, who immediately left the contest after his catch, would need to be placed on the injured list.
Seattle’s lineup is in need of a spark, as the 6-10 Mariners have scored just 49 runs this season, which is tied for 27th out of MLB’s 30 teams. Their 167 strikeouts are the third-most in the league, and their .204 average and .590 OPS also rank third from the bottom.

Projected Lineup: Feb. 26 vs. Seattle | St. Louis Blues
The St. Louis Blues are back in action as they host the Seattle Kraken on Thursday at Enterprise Center (7 p.m., FanDuel Sports Network Midwest, 101 ESPN).
It will be the team’s first game since Feb. 4, and Jim Montgomery said the squad is ready to get back to work.
“Yeah, I think everybody is,” the head coach said. “I mean, you can tell. Guys were anxious today, but it’s like ‘enough of practicing against each other, it’s time to play a game.’”
Captain Brayden Schenn, who missed Wednesday’s practice with an illness, took the morning skate and is expected to play. Dylan Holloway (ankle), who has played just one game since Dec. 12, will make his return to the lineup as well.
Robert Thomas has taken a leave of absence due to a personal matter. He’s expected to return to the team on Friday.
Additionally Jack Finley will make his Blues debut. Finley – who is the son of former Blue Jeff Finley and was born in St. Louis – was claimed off waivers by the team on Feb. 7.
“It was a dream of mine to play for this team,” Finley said. “It was a big part of my childhood, big part of my family’s life. So definitely full-circle moment and proud to be a Blue.”
Jeff, who played defense for the Blues from 1998-2004, will be in the building Thursday night to see his son don the jersey he wore for so many years.
“He was excited,” Jack said about his dad. “Maybe more excited than me. He loved this organization, loved this city… He’s excited to be back.”

What Donovan brings to Seattle Mariners’ leadoff spot
The Seattle Mariners improved quite a bit offensively a year ago, but they were still lacking when it came to production from the top spot in their lineup.
Josh Naylor shows friendly side by greeting history-making umpire
Despite being a top-10 offense in runs scored, Mariners leadoff hitters were near the bottom of the league in several categories, including 27th in OPS and 24th in both on-base percentage and wRC+.
It’s an area the club can stand improve this season, and it’s also one that figures to have a different look with newly acquired Brendan Donovan expected to open the season in the leadoff spot.
How does what Donovan brings to the table improve the Mariners’ top spot line the lineup? Mike Salk broke it down on a recent edition of Seattle Sports’ Brock and Salk.
‘Just a better hitter’
The Mariners were forced to change their leadoff plans early last year when Victor Robles suffered a fractured shoulder on their first road trip. They used a combination of Julio Rodríguez and Dylan Moore in his place for a brief stint before J.P. Crawford assumed the role for an extended period. And in late July, they settled on Randy Arozarena for the remainder of the season.
There are some productive hitters in that group, but Mariners leadoff hitters finished with an underwhelming .237/.311/.348 slash line and .659 OPS. Arozarena struggled there in particular, hitting .218 with a .302 on-base percentage and .645 OPS in the leadoff role.
Insert Donovan, who has a career .282/.361/.411 slash line with a .772 OPS over four seasons. M’s leadoff hitters did have more home runs (15) than Donovan’s 162-game career average (13), but Donovan’s average of 32 doubles is a bit better than the 28 hit from Seattle’s leadoff spot in 2025.
“So the idea is he should be getting on base more,” Salk said. “He should be hitting more doubles and putting pressure on the other team. He should have a higher batting average by another 50 points or so, and the OPS should be a lot (higher). He’s just a better hitter, just a flat out better hitter than what they had at that position last year.”
Brendan Donovan makes a mark in Mariners Cactus League debut
Another area that stood out to Salk was the strikeout disparity. Donovan is averaging 89 strikeouts over 162 games compared to the 165 totaled by M’s leadoff hitters in 2025.
“It’s a crazy difference,” he said.
A ‘real pest’
Donovan’s patience and ability to make contact make him a hitter capable of grinding out a pitcher and elevating their pitch count, but he actually saw less pitches per plate appearance last season than Crawford and Arozarena, who accounted for 82.5% (599 of 726) of the Mariners’ plate appearances from the leadoff spot. Crawford averaged 4.17 pitchers per plate appearance and Arozarena 4.05, while Donovan averaged 3.72.
But the difference to Salk is what Donovan does when he gets deep into counts.
“It’s not like they haven’t had guys with the ability to take pitches and grind through at-bats. All of those guys are capable of doing that, but I think what you get from Donovan is he’s able to grind through the at-bats and make them pay off by getting on base, by coming up with hits, by avoiding strikeouts, by an OPS and even a slugging percentage that are a step up from what the Mariners have had in that spot in the past,” Salk said.
“You’re not gonna hit a lot of home runs. That’s not his game, but if and when he does kind of figure out T-Mobile Park and what that looks like, he should be a real pest. He should be really annoying to play against and he should help the guys who hit right after him by putting more pressure on the pitcher and exhausting him.”
