Diego Castillo has joined the Texas Rangers organization…

The 29-year-old Dominican professional baseball pitcher, a veteran reliever, is among seven free agents who’ve signed minor league contracts with the Texas Rangers that include invitations to spring training with the World Series champions.

The Rangers announced the signings Wednesday of Castillo and two other right-handed pitchers, Gerardo Carrillo and Jesus Tinoco, along with catcher Andrew Knapp and outfielders Sandro Fabian, Elier Hernandez and Derek Hill.

Castillo has a 24-18 record with 35 saves and 3.22 ERA over six big league seasons with Tampa Bay Rays (2018-21) and Seattle Mariners (2021-23), with opponents hitting only .200 against him. The right-hander, who turns 30 on January 18, allowed six earned runs over 8⅔ innings in eight relief appearances for the Mariners last season.

Tinoco had a 2.93 ERA in 38 appearances this year for the Saitama Seibu Lions of the Nippon Professional Baseball Organization in Japan. Before that, he made 48 appearances over four big league seasons with the Colorado Rockies (2019-21), Miami Marlins (2021) and Texas (2022). He pitched in 17 games for the Rangers, and in one of his two starts allowed the 62nd home run hit by New York Yankees star Aaron Judge to break the AL single-season record.

Rangers pitchers and catchers will have their first spring training workout in Surprise, Arizona, on February 14.

The first full-squad workout is scheduled for February 19.
