EXTRA BASES: The Dodgers scored a season-high 12 runs and ended a three-game losing streak, but they weren't all smiles. Andre Ethier and Manager Don Mattingly appeared to be engaged in a heated argument in the dugout in the bottom of the eighth inning. When Ethier disappeared down the clubhouse tunnel, he was followed by Mattingly. Ethier, who struck out an inning earlier, played dumb when asked about the incident. "I guess you guys misinterpreted," Ethier said. "You're looking too far into it." Ethier and Mattingly have had differences over the years. In the wake of the 2011 season, Mattingly estimated that Ethier's lack of emotional control resulted in his squandering 100 at-bats. Last year, Mattingly benched Ethier on a day on which he publicly questioned his team's mental toughness.
