The Washington Nationals today recalled left-handed pitcher John Lannan from Harrisburg of the Double-A Eastern League. Additionally, right-handed pitcher Jordan Zimmermann was returned from rehab and reinstated from the 60-Day Disabled List then optioned to Syracuse of the Triple-A International League. Nationals Senior Vice President and General Manager Mike Rizzo made the announcements.
Lannan went 1-4 with a 4.20 ERA in seven starts with the Senators. The 25-year-old posted a 3.48 ERA, 18 strikeouts and 6 walks in 20.2 innings over his final four starts at Double-A.
The Nationals' Opening Day starter each of the last two seasons, Lannan is 2-5 with a 5.76 ERA in 14 starts with Washington in 2010. He is 22-35 with a 4.19 ERA in 84 starts during his four big league seasons.
Zimmermann, 25, is 0-2 with a 2.38 ERA after six rehab starts with Potomac of the Single-A Carolina League, Hagerstown of the Single-A South Atlantic League and most-recently Harrisburg. He began the season on the DL, recovering from "Tommy John" ligament-replacement surgery performed on August 19, 2009.
