Arizona Diamondbacks' Daniel Hudson throws against the San Francisco Giants during the first inning in a MLB baseball game Saturday, April 7, 2012, in Phoenix.

PHOENIX — Aaron Hill hit two homers, Chris Young had a pair of run-scoring doubles and the quick-striking Arizona Diamondbacks beat the San Francisco Giants 5-4 on Saturday.

The kings of the comeback last season, the Diamondbacks have been fast starters in 2012, scoring seven runs the first two innings their first two games.

Hill drove in three of those: A solo homer off Madison Bumgarner (0-1) in the first inning and a two-run shot in the second. Young also hit the first of his RBI doubles in the first, giving starter Daniel Hudson (1-0) just enough cushion to open with a victory after struggling early last season.

J.J. Putz worked a perfect ninth for his second straight save.

Pablo Sandoval and Brett Pill each hit two-run homers for the Giants.
