A series against the MLB-leading St. Louis Cardinals has come at a bad time for the Arizona Diamondbacks, who had been trying to close the gap in the NL West. The Diamondbacks hope to bounce back with a rare victory over the Cardinals on Tuesday night, though Jaime Garcia will be looking to win his fifth straight start against them. The Diamondbacks couldn't sustain that pace in Monday's 5-3 loss to St. Louis (79-45), failing to trim their division deficit to 4 1/2 games behind the idle Los Angeles Dodgers.
