PHOENIX (AP) -- Angel Pagan hit a three-run home run in San Francisco's five-run eighth inning and the Giants rallied to beat the Diamondbacks 8-5 on Thursday in a game that was halted briefly in the top of the first due to a swarm of bees in the outfield.
Paul Goldschmidt and Mark Trumbo each hit two-run home runs as Arizona led 5-3 after seven, but the Giants teed off on reliever Will Harris (0-1) in the eighth to take three of four games from the Diamondbacks.
Brandon Belt hit his third home run of the series and Brandon Hicks had a pinch-hit solo shot for the Giants, who had rallied from four down to win the series opener Monday.
Goldschmidt homered in the first inning off Tim Lincecum, his sixth homer in 21 career at-bats against the Giants right-hander.
Jean Machi (2-0) got one out for San Francisco to earn the victory. Machi also got the win in the Giants' season opener.
Goldschmidt extended his hitting streak to 25 games, second-longest in franchise history. He also doubled to improve to 12 of 23 against Lincecum with 13 RBIs.
With a pair of season-opening losses to the Dodgers in Australia, the D-backs have started the season 1-5.
Bronson Arroyo, sidelined most of the spring with a sore back, was lifted after 4 1/3 innings in his Arizona debut.
Pagan, who had three hits, homered on the first pitch after the Giants tied it at 5.
With the Diamondbacks leading 5-3, Hunter Pence drew a one-out walk in the eighth and scored on Hector Sanchez's double. Pinch-hitter Buster Posey was walked intentionally and Michael Morse's pinch-hit single up the middle tied it. That brought up Pagan, who hit the first pitch into the swimming pool area in right field to put San Francisco on top.
Arizona's Aaron Hill had three hits, including an RBI double, and scored twice.
Belt's two-out homer off Arroyo in the first inning, his third in his first 14 at-bats this season, put the Giants up 1-0.
Hill singled with one out in the bottom of the first to bring up Golsdschmidt, who hit the first pitch he saw into the pool area.
San Francisco tied it at 2-all in the fourth. Pablo Sandoval led off with a double down the left field line, advanced to third on Pence's single and scored on Sanchez's sacrifice fly to center.
Arroyo gave up a leadoff double to Pagan to start the fifth. Pagan took third on Gregor Blanco's sacrifice bunt and Arroyo's day was over. Left-hander Oliver Perez got Belt and Sandoval to pop out to end the threat.
Hicks' shot to left off Josh Collmenter with one out in the seventh cut the lead to 4-3. It was his fourth career homer and first as a pinch hitter.
Arizona added a run with two outs in the seventh, with Hill doubling to the wall in left off Machi to score Gerardo Parra from first.
NOTES: The Diamondbacks' franchise-record hitting streak is 30 games by Luis Gonzalez from April 11-May 18, 1999. ... Arizona opens a three-game series in Colorado Friday, going with right-hander Randall Delgado against Rockies right-hander Juan Nicasio.
