SEATTLE — The Seattle Mariners quickly found a replacement for the back end of their bullpen, acquiring right-hander Diego Castillo from the Tampa Bay Rays for reliever JT Chargois and a minor league infielder on Thursday.
Castillo will likely jump into the closer role that was vacated when the Mariners traded Kendall Graveman to the Houston Astros earlier in the week. But unlike Graveman, who will be a free agent after the season, the Mariners gain a significant amount of control for the future with the acquisition of Castillo.
“I’ve said all along that we were focused on doing what we could to improve our team now and to continue to improve our team for 2022 and beyond. We feel like we’ve accomplished that,” Mariners general manager Jerry Dipoto said. “I can’t tell you that we will make another deal between now and the deadline but we’re not intentionally done. If we’re done it’s just because we weren’t able to get anything across, but we do have other things going.”
Castillo, 27, has 14 saves in 37 appearances and a 2.72 ERA this season for the Rays. He had a 1.66 ERA in 21 appearances during the shortened 2020 season for Tampa Bay. Castillo also appeared in 10 postseason games last year for Tampa Bay and allowed two earned runs in 11 innings.
