Right-hander Luis F. Castillo, designated for assignment by the Seattle Mariners a day earlier, landed with a new team on Wednesday when the Baltimore Orioles acquired him in a cash deal.

The Orioles optioned him to Triple-A Norfolk.

Castillo, 30, made two starts for Seattle early in the season before he was optioned back to the minors. He was 0-0 with a 7.71 ERA, five strikeouts and seven walks in seven innings for the Mariners.

In four starts for Triple-A Tacoma this year, Castillo was 0-1 with a 5.02 ERA. He struck out 12 and walked five in 14 1/3 innings.

Castillo was taken off Seattle’s 40-man roster this week following the team’s acquisition of outfielder Leody Taveras from the Texas Rangers.

Prior to this year, Castillo made his only major league appearances for the Detroit Tigers in 2022, working three games in relief. He had no decisions while throwing 3 2/3 shutout innings.

The Wednesday move leaves the Mariners with just one player named Luis Castillo: three-time All-Star right-hander Luis M. Castillo.

Baltimore opened a place on the 40-man roster for Luis F. Castillo by designating left-hander Walter Pennington for assignment. Pennington, 27, never appeared in a game for Baltimore. He was 0-2 with a 45.00 ERA in two games (one start) in the Orioles’ farm system this year.

Pennington debuted in the majors last year, going a combined 1-0 with a 3.00 ERA in 16 games (one start) for the Kansas City Royals and Texas Rangers.
