Jake McCarthy, Lourdes Gurriel Jr., Randal Grichuk and James McCann homered to lead the Arizona Diamondbacks to an 8-2 win against the San Francisco Giants in the second game of their four-game series on Tuesday night in Phoenix.
Geraldo Perdomo added two hits and an RBI for Arizona, which ended a four-game skid with a 4-2 win in the series opener on Monday.
Diamondbacks starter Zac Gallen (6-9) delivered his best start in nearly a month, allowing two runs (one earned) and five hits in seven innings. The 2023 NL All-Star struck out 10 and didn’t walk a batter.
Giants right-hander Hayden Birdsong (3-3) allowed four runs (three earned) and three hits in four innings. He struck out six, but walked four.
Willy Adames homered for San Francisco, which has lost four in a row to match its season high.
Adames gave the Giants a 1-0 lead when he homered to left-center field with one out in the second, his 10th of the season and 20th allowed by Gallen.
Daniel Johnson then doubled into the right-center field gap and continued to third on an errant relay throw before scoring on a weak grounder to first by Patrick Bailey to make it 2-0.
Birdsong allowed his first base runner when McCann walked with one out in the third. He moved to second on a passed ball and scored on a two-out single by Perdomo that sailed just over the head of second baseman Tyler Fitzgerald, cutting the lead to 2-1.
Things continued to unravel for Birdsong in the fourth.
He walked the first two batters on eight pitches before McCarthy smashed a 2-0 fastball into the seats in right-center for a three-run homer and a 4-2 lead.
Carson Seymour took over to start the fifth for San Francisco and got the third out of the inning on a strikeout, but the pitch got away from Bailey for another passed ball, allowing Eugenio Suarez to reach base.
Gurriel then lifted a sinker over the fence in left-center to stretch the lead to 6-2.
Grichuk, who was a late addition to the lineup at designated hitter after Josh Naylor was scratched (neck stiffness), doubled off the warning track in right-center field in the fourth and blasted a solo home run deep over the fence in center in the sixth to make it 7-2.
McCann followed with a deep home run to left to stretch it to 8-2.
