Seattle Mariners Shut Down Bryce Miller With Arm Issue

Bryce Miller's last start for the Seattle Mariners was Mother's Day at T-Mobile Park against the Toronto Blue Jays. He was belted for seven runs on eight hits through five innings pitched.

In the postgame, Miller stated that he has been experiencing some arm soreness and back tightness on and off during the season. He's been placed on the 15-day injured list with right elbow inflammation.

In his 2025 campaign so far, Miller has racked up a record of 2-4 through eight games, a 5.22 ERA over 39.2 innings pitched, and 35 punchouts with a 1.54 WHIP. 

In the corresponding move, the M's recalled left-hander Jhonathan Díaz from the Triple-A Tacoma Rainiers. Díaz has only appeared in one game in 2025, and pitched 1.1 innings in relief and recorded a strikeout on April 1.

So far, through seven appearances for the Rainiers, Díaz has a 2-3 record with a 5.87 ERA over 30.2 innings pitched and 27 punchouts with a 1.47 WHIP. 

Another crucial blow to this already battered Seattle rotation as Miller becomes the third M's pitcher to land on the IL behind Logan Gilbert and George Kirby.
