SAN DIEGO - It's not easy to upstage a first-inning grand slam, a seven-RBI night, an unbeaten starting pitcher, a 53-home run month and the winningest June in franchise history.But Dave Roberts did it.The Dodgers manager charged San Diego Padres manager Andy Green during a meeting at home plate before the second inning, setting off a benches-emptying scrum during which Roberts had to be restrained from going after Green further.
