The Orioles have designated right-hander Lou Trivino for assignment, according to Roch Kubatko of MASN Sports. Right-hander Jose Espada is being recalled from Triple-A in a corresponding active roster move. With this news, the club’s 40-man roster is at 39 players.

Trivino had only signed a major league deal with Baltimore six days ago. He appeared in two games with radically different results. On May 4th against the Yankees, Trivino got lit up for six earned runs on four hits and three walks while recording just two outs. He was much better yesterday against the Athletics, striking out three hitters in 2 1/3 scoreless innings. Trivino’s designation suggests that the club was only looking for a short-term solution in the bullpen, or that they were not confident in his abilities after the May 4th blow-up. In any case, the move allows Baltimore to swap out Trivino for a fresh arm in Espada.

More to come.
