The Dodgers find themselves a game over .500 with a quarter of the season already gone. ''We know we're better than that,'' new manager Dave Roberts said after an 8-1 loss to the Los Angeles Angels on Wednesday night in the Freeway Series. Joc Pederson's RBI single in the fourth provided the Dodgers' lone run, a night after they limited the Angels to one run in a 5-1 victory.
