Jonatan Clase is a 23-year-old (24 in May), switch-hitting outfielder from Santo Domingo, Dominican Republic. He came to us in trade from the Mariners, along with catcher Jacob Sharp, for Yimi Garcia. Sharp played in New Hampshire in 2025, hitting .161/.271/.206 in 68 games

He has played 60 major league games, and lost his rookie status in 2024. In the 60 games, he’s hit .224/.294/.311 with 3 home runs, 6 steals, caught 2 times.

The big news is the MLB has given the Jays one more option year on Clase. Well, good news for the Jays, I’m not so sure it is good for Jonatan. It makes him less likely to be DFAed. But then, if he were on another team, he would be more likely to find a spot on the active roster. With the Jays, he looks to be waiting for an injury or two. He would be a good choice for the 27th man when we have a doubleheader. If you had room on your active roster, he would be the perfect guy to pinch-run in extra innings, being the Manfred Mann. And he would be an excellent defensive replacement. But then, he’d still have to hit better than .161.

At the moment, I’d think he would be behind Joey Loperfido, Yohendrick Piñango, as well as spring training invites RJ Schreck and Elroy Jiménez (though the latter two aren’t on the 40-man roster at the moment) in line for a job in the majors if there is an injury. Of course, we have Daulton Varsho, George Springer, Anthony Santander, Nathan Lukes, Myles Straw, Davis Schneider and Addison Barger all who can play outfield and are expecting a spot on the active roster (I’m not sure how all of them can make it).

Clase played 87 games for the Bisons, last year, hitting .255/.335/.403 with 7 home runs and 30 steals (caught just 4 times). His defense is good, with the occasional poor route (but he generally makes up for that with his speed).

As much as I like him, I really don’t see a path to him getting major league at-bats. I guess a terrific spring training would help.

I often compare him to Otis Nixon. Nixon didn’t have a MLB season with over 200 PA until age 29. Nixon had 727 PA before age 30 and 5073 after age 30. So don’t count Jonatan out. Clase has more power than Nixon had and is a better defensive outfielder.

Steamer projects he will appear in 12 MLB games, hitting .225/.294/.367 in 45 plate appearances.
