The Nationals have placed 31-year old righty swinging LF Josh Willingham on the 15-day disabled list with a medial meniscus tear in his left knee. This injury will likely end his 2010 season. Willingham played in 114 games for the Nationals this year and he was 99 of 370 (.268 avg, .848 OPS) with 54 runs scored, 16 homers, 56 RBIs and 8 stolen bases. The Nationals will miss Willingham’s power. The Nationals have activated 29-year old lefty swinging outfielder Nyjer Morgan to replace Willingham on the active roster and in the outfield. He has played in 103 games for the Nationals this year and he is 103 of 394 (.261 avg, .644 OPS) with 47 runs scored, 20 RBIs and 29 stolen bases.
