NEW YORK - The Nationals may have set their 25-man roster for opening day, but the club continues to tinker with its organizational depth chart.
The Nats announced Sunday that veteran left-hander Aaron Laffey has been signed to a minor league deal. The 28-year-old native of Cumberland, Md., has a 25-29 record and 4.45 ERA in 153 career games (68 starts) with the Indians, Mariners, Yankees, Blue Jays and Mets. Last season, he worked to a 7.11 ERA in five major league games, and went 6-8 with a 6.34 ERA in 23 Triple-A appearances for three different organizations.
Laffey went to major league spring training on a minor league contract with the Orioles, but was released.
The Nationals also swung a minor league trade with the White Sox, acquiring right-hander Omar Poveda in exchange for cash considerations. The 26-year-old was 6-7 with a 3.62 ERA in 27 games (25 starts) with Triple-A Gwinnett, the Braves’ top farm club.
