If the Los Angeles Dodgers and Washington Nationals meet in this year's playoffs, the addition of Roberto Hernandez may give Los Angeles an edge. The veteran right-hander has beaten the Nationals twice without allowing an earned run and will face them again Monday night at Dodger Stadium. The Nationals (77-58) own the NL's best record and are atop the East while the West-leading Dodgers (77-60) are one game behind them in the race for the top seed entering this three-game set. Exactly one month ago, Hernandez (8-9, 3.81 ERA) limited Washington to one unearned run over eight innings to earn a 2-1 victory in his final start with Philadelphia.
