Done with the rigors of the road, for now anyway, the Los Angeles Dodgers will return home Friday night to face both the Miami Marlins and a familiar concern: a bullpen that has been the weak link in an impressive season. The Dodgers left Philadelphia where they split a four-game series, losing the two games when the bullpen coughed up late leads. The most recent came Thursday when the Dodgers had a 5-3 lead in the seventh inning, only to lose when the Phillies scored four times in the frame.
