Up next: Paul Maholm will start for the Dodgers on Thursday against Cincinnati in a game that can be seen on MLB.TV at 1:05 p.m. PT. Maholm is coming off an impressive three-inning outing, followed by an equally impressive bullpen session. The Dodgers could send out essentially their regular-season lineup. Tim Wallach will again manage in the absence of Don Mattingly, who is expected back in camp Friday after a death in the family.
