LOS ANGELES - Maybe the worst thing Dodgers manager Don Mattingly didSaturday night was limit Tony Gwynn Jr. to one at-bat against hisformer Padres teammates. Gwynn, who secured Friday night's victory with a game-endingdiving catch, delivered the game-tying run in the seventh Saturdaynight with a pinch single. But San Diego broke that tie in the topof the eighth with three runs off Matt Guerrier, en route to a 5-2victory before an announced crowd of 34,453 at Dodger Stadium. Guerrier's bases-loaded wild pitch scored Will Venable with thego-ahead run. Cameron Maybin's bases-loaded single to left scoredtwo more, with Chase Headley knocking the ball out of catcherDioner Navarro's mitt to score the second one.
