The Orioles today announced that they have acquired right-handed pitcher LUIS F. CASTILLO from the Seattle Mariners in exchange for cash considerations. He has been optioned to Triple-A Norfolk.
Castillo, 30, has a 7.71 ERA (6 ER/7.0 IP) with 12 hits, seven total runs, and seven walks with five strikeouts in two major league starts for the Mariners this season. He’s also made four starts for Triple-A Tacoma, going 0-1 with a 5.02 ERA (8 ER/14.1 IP). Castillo opened the year in Triple-A before having his contract selected on April 4. He was optioned back to Tacoma on April 10, and was designated for assignment yesterday.
Castillo made his MLB debut with the Detroit Tigers in 2022, working 3.2 scoreless innings in three games. He spent the last two seasons in Japan, pitching for the Orix Buffaloes in 2024 and Chiba Lotte Marines in 2023. In two years in Nippon Professional Baseball, Castillo went 6-8 with a 3.01 ERA (48 ER/143.1 IP) with 21 walks and 108 strikeouts in 27 games (24 starts). He also made 10 appearances (nine starts) for the farm teams. He originally signed with the Arizona Diamondbacks as an international free agent on February 16, 2012, out of Fantino, Dominican Republic.
To make room on the 40-man roster, left-handed pitcher WALTER PENNINGTON has been designated for assignment. The Orioles’ 40-man roster currently has 40 players.
