Diego Castillo

Diego Castillo earned the win on Wednesday against Houston, allowing one hit over one scoreless inning with three strikeouts.

Fantasy Impact

Castillo has looked dominant in back-to-back appearances. It is possible he gets another opportunity to close out games for Seattle with Paul Sewald giving up runs back-to-back appearances himself.

Diego Castillo earned the save on Saturday against Arizona, working around a hit to toss as scoreless inning.

Fantasy Impact

Castillo was activated from the injured list the same day, showing little rust as he worked around a leadoff single to Daulton Varsho. His leash will likely be short as the Mariners closer with Paul Sewald and Drew Steckenrider pitching very well as of late.

Seattle Mariners pitcher Diego Castillo (shoulder) was placed on the 10-day injured list with right shoulder inflammation.

Fantasy Impact

Castillo struggled in his previous appearance, blowing the save, surrendering two earned runs over an inning. The shoulder injury could explain his recent struggles, and he will miss at least the next 10 days. Paul Sewald will handle closing duties for the Mariners while Castillo is sidelined. Sewald has been terrific in 2021, owning a 2.63 ERA, 0.90 WHIP, and 67 strikeouts over 41 innings. Fantasy managers in search of saves should add Sewald in all league formats.

Diego Castillo blew the save on Thursday against Texas, allowing two runs on one hit over one inning with two strikeouts and one walk.

Fantasy Impact

Castillo entered a situation in the ninth inning with runners on second and third, nobody out and the Mariners up 7-3. After striking out the first batter he faced, he walked the next batter on a pitch that also scored a run on a wild pitch. He picked up another strikeout for the second out of the inning before allowing a gut wrenching three-run long ball that tied the game to blow a phenomenal start by Chris Flexen. Paul Sewald later picked up the save in the 11th inning. This will be a situation to monitor to see if Sewald eventually takes over the closer role in the Mariners bullpen.

Diego Castillo earned the hold on Tuesday against Texas, working around two runners on base to toss a scoreless inning.

Fantasy Impact

Castillo once again entered the game in the eighth inning with Paul Sewald earning the save opportunity. After allowing a single and hitting a batter, Castillo escaped the jam thanks to a nifty double play started by J.P. Crawford.
