Jorge De La Rosa (1-0) picked up the win in relief for the D-backs while Jeff Samardzija (0-1) took the loss.
MOMENTS THAT MATTERED
Lamb chop: It was a rough first two at-bats for Lamb, who struck out swinging in the second and looking in the fourth. In the sixth, though, he delivered the big blow of the game with a three-run homer to right-center, which gave the D-backs the lead for good at 5-3.
Big hit proves elusive: All series long, the Giants lacked the truly conclusive base hit that would put away a ballgame in their favor.
