Diamondbacks beat Giants 5-4 in 12 inningsPosted: Updated:
PHOENIX (AP) -- Conor Jackson hit a bases-loaded single in the 12th inning, lifting the Arizona Diamondbacks to a 5-4 victory over the San Francisco Giants on Sunday.
The Diamondbacks tied it at 4 with a three-run ninth inning, capped by Justin Upton's two-run homer off Giants closer Brian Wilson.
The winning rally began when former Diamondbacks reliever Brandon Medders (0-1) walked leadoff man Miguel Montero. Montero moved up on Chris Young's bunt, and then Medders walked Felipe Lopez intentionally and Augie Ojeda unintentionally to load the bases.
San Francisco manager Bruce Bochy summoned Justin Miller, who gave up a line drive single to Jackson to deep left field.
Juan Gutierrez (1-1) pitched 12th for the Diamondbacks.
