Mariners' Jhonathan Diaz: Dominating at Tacoma

Diaz has pitched to a 3-0 record, 0.38 ERA and 0.75 WHIP across 24 innings over his first four starts for Triple-A Tacoma.

The 27-year-old southpaw has taken well to his new organization after signing a minor-league deal with the Mariners in January. Diaz has allowed just a single earned run for the Rainiers -- all the more impressive given the fact he's toiling in the hitter-friendly Pacific Coast League. Diaz mustered a 2-1 record and 3.49 ERA across 28.1 innings during his first two big-league stints with the Angels in 2021 and 2022, but he had a rough seven-inning tenure with Los Angeles last season during which he posted a 10.29 ERA and 2.86 WHIP. Control has been a persistent issue during Diaz's brief big-league stays in the past, but his elite 27:1 K:BB thus far with Tacoma suggests he may be starting to turn a corner in that department.
