Mariners Get Ruling On Arbitration Case With Diego Castillo

The Seattle Mariners and five-year veteran reliever Diego Castillo took their contract stand-off to arbitration today, and the player will now have to settle for a 'mere' $2.95M this coming season.

Castillo, a five-year veteran, had filed for $3.225M, but will have to settle for $230,000 less, as the case was ruled in favor of the club.

The 29-year-old arrived in Seattle at the trade deadline in 2021, and immediately slotted into the high-leverage mix at the back-end of the bullpen. He posted a couple of saves along with a 2.86 ERA and a 0.95 WHIP in the two months to finish the '21 season, while striking out 10.6 batters per nine innings.

In 2022, he recorded seven saves and a 3.64 ERA with a 1.14 WHIP, though his strikeout rate was down, to 8.8 K/9. 

He'll once again join the late-innings mix for the Mariners this season, with the likes of Paul Sewald, Andrés MuñozPenn Murfee and Matt Brash.
