The Orioles remained active in the trade market on Monday, making a deal just before the 4 p.m. deadline when they sent right-handed reliever Miguel Castro to the New York Mets for minor league left-hander Kevin Smith and a player to be named later or cash.
Castro, 25, who came to the Orioles in April 2017 from the Colorado Rockies for a player to be named later that turned out to be minor league right-hander Jon Keller, was 7-13 with a 4.06 ERA in four seasons with the Orioles.
Before Monday’s game, manager Brandon Hyde said that Castro hadn’t been used since Friday because he had sinus issues.
Castro was 1-0 with a 4.02 ERA and a save in 16 games with the Orioles this season.
Smith, 23, who was at the Mets’ alternate site in Brooklyn, was 8-7 with a 3.15 ERA in 23 games at High-A St. Lucie and Double-A Binghamton last season.
He was the 11th-rated prospect, according to MLB Pipeline, and had 130 strikeouts in 117 innings in 2019.
When the Orioles play the Mets on Tuesday at Camden Yards, they’ll have to add a player to fill Castro’s roster spot.
There are 38 players on the 40-man roster and 58 in the 60-man player pool.
