Manager Don Mattingly, asked about what the return of a healthy Matt Kemp for the second half could mean to the slumping Dodgers, said before Wednesday's series finale against the San Francisco Giants the potential impact of arguably the game's best player was "huge." "It's like having a one-two punch without having the one," Mattingly said. On a day when the San Francisco Giants defeated the Dodgers 3-0 in front of 42,245 at AT&T Park to complete a three-game sweep with their third consecutive shutout, the Dodgers might have lost the two as well. Andre Ethier, second in the National League in RBIs with 55, left the game in the first inning with a left oblique injury.
