The Minnesota Twins recalled right-hander
Diego Castillo from Triple-A St. Paul on Tuesday and transferred reliever
Justin Topa (knee) to the 60-day injured list in a corresponding move to make room for Castillo on the 40-man roster. Castillo is a veteran of six major-league seasons with the Tampa Bay Rays and Seattle Mariners. He's a sinker-slider reliever with mid-90s velocity, a 3.22 ERA and 304 strikeouts in 268 career MLB innings. The 30-year-old earned the call-up to the big leagues by posting a 2.50 ERA, a 1.06 WHIP, five saves and 22 strikeouts in 18 relief innings for St. Paul. The Dominican reliever has 35 saves in his six major-league seasons and will give the Twins some veteran setup depth in the later innings moving forward.

The Texas Rangers signed free-agent right-handers

Derek Hill, and catcher
Andrew Knapp to minor-league deals with invitations to major-league spring training on Wednesday. Castillo, 29, allowed six earned runs in just 8 2/3 relief innings for the Seattle Mariners this year, but he saved a career-high 16 games in 2021 with the M's and Tampa Bay Rays and will give the Rangers some experienced relief depth entering the 2024 campaign. Knapp, 32, has spent parts of six seasons in the big leagues with four different teams and has slashed .209/.310/.313 with 13 home runs and 66 RBI in 325 games. The switch-hitting backstop hit .233 (73-for-313) with nine home runs and 29 RBI in 93 games with Triple-A Sugar Land and Triple-A Toledo with the Astros and Tigers, respectively.

Seattle Mariners reliever
Diego Castillo has been optioned to Triple-A Tacoma. Castillo has struggled, as have most of the Mariners, so this shouldn't come as too much of a shock. The 29-year-old right-hander posted a rough 6.23 ERA, 1.62 WHIP, and 7:7 K/BB ratio over 8 2/3 innings out of the bullpen so far this year. His services will likely be called upon again soon with the big league club so he shouldn't be in the minors for too long.

Seattle Mariners relief pitcher
Diego Castillo lost his salary arbitration case against the team on Wednesday, according to a source. Castillo will make $2.95 million in 2023, instead of the $3.225 million he filed for. In his first full season with the Mariners in 2022, Castillo went 7-3 with a 3.64 ERA (3.68 FIP), 1.14 WHIP, seven saves, 22 walks and 53 strikeouts in 54 1/3 relief innings over 59 appearances out of the bullpen. The 29-year-old right-hander could see a handful of save chances again in 2023, but he'll mostly be serving as a late-inning setup man in Seattle's bullpen alongside
Andres Munoz.
Paul Sewald is coming off injury, but he's projected to begin the year as the M's primary closer.
