Lannan is a 6-5, 200-pound lefty. Though injuries to the starting rotation are one reason for Lannan's rise to the majors, another is merit. Lannan was 3-1 with a 1.75 ERA in six starts for Triple-A Columbus and was 12-3, 2.35 in 20 minor-league games overall this season.
Despite his 6-5 frame, Lannan isn't said to be a particularly hard thrower. His fastball gets only into the high 80s, but it has lots of movement. He'll also throw a changup and curve effectively.
Lannan was an 11th round selection out of Siena (N.Y.) College and is the 22nd pitcher the Nationals will use this season and the 12th to start a game. The Phillies have used 25 pitchers this year, and 10 starters.
