After officially re-signing first baseman Logan Morrison, the Rays traded left-handed pitcher Enny Romero to the Nationals for right-handed pitcher Jeffrey Rosa. The deal freed up a spot on the 40-man roster for Morrison.
The 26-year-old Romero spent the entire 2016 season in the Rays bullpen. In 45 2⁄3 innings, he owned a 5.91 ERA with 50 strikeouts and 28 walks. In his major league career, he’s thrown 80 1⁄3 innings in 76 appearances, all but one of which came out of the bullpen. He has a career ERA of 5.23.
In his career, the lefty has a pronounced reverse split. Left-handed batters have a .880 OPS against Romero, over 200 points higher than righties’ OPS against him.
Rosa, 21, made his U.S. debut for the Gulf Coast League Nationals in 2016. He had a 4.91 ERA in 40 1⁄3 innings with 34 strikeouts and 20 walks, but he only allowed one home run.
Baseball America’s Ben Badler named Rosa as one of the 20 best prospects in the Dominican and Venezuelan Summer Leagues in 2015 (BA, $). He was already 20 when the Nationals signed him, but his fastball can reach 100 miles per hour. He still needs a lot of work to harness that into good results on the mound.
