Nate McLouth says left patellar tendonitis flared up in the outfield pre-game. He's dealt with it for years. Hopes it subsides by tonight.

McLouth, 32, was signed by the Nationals as a free agent to a 2-year $10.75 million contract (option for 2016), in order to supplement the Nationals' bench. A part-time player for most of his career, McLouth played 146 games at left, center and DH for the Baltimore Orioles in 2013, slashing .258/.329/.399 with 12 home runs and 30 stolen bases.
McLouth has already played in 9 of Washington's first 11 games (2 for 13). The Nationals' outfield is without centerfielder Denard Span (concussion) so McLouth was originally scheduled to start in center field today, with Bryce Harper manning his usual left field and Jayson Werth in right. Harper was moved to center, batting second, with Frandsen taking left.
