MILWAUKEE (AP) — Casey Schmitt homered on the game’s first pitch, Eric Haase hit the Giants’ fifth grand slam in a 17-game span as they opened a nine-run lead, and San Francisco beat the Milwaukee Brewers 12-9 Thursday for a a four-game split.

Jung Hoo Lee had four of the Giants’ 20 hits, and Chapman and Bryce Eldridge three each. San Francisco scored six times in the seventh inning, opening a 12-3 lead.

Jackson Chourio homered twice for Milwaukee and David Hamilton once.

Schmitt hit his 13th homer with his drive on a fastball from Coleman Crow (0-1), who allowed six runs and nine hits in 2 1/3 innings. Crow, whose ERA rose from 3.14 to 5.94, had not allowed more than two earned runs in each of his three previous major league starts.

Sam Hentges (1-0) got the final two outs of the fifth inning in relief of Adrian Houser for his first big league win since Sept. 2, 2023, for Cleveland against Tampa Bay. Caleb Kilian entered after Wilkin Ramos’ bases-loaded walk with no outs in the ninth, struck out Andrew Vaughn, got Sal Frelick to ground into a forceout at second, gave up Luis Rengifo’s RBI single, then retired David Hamilton on a flyout to the center-field warning track for his fourth save.

The Giants built a 3-0 lead in the first on Schmitt’s homer, Eldridge’s RBI single and Chapman’s run-scoring double. William Contreras’ sacrifice fly cut the deficit in the bottom half and Lee, Chapman and Schmitt drove in runs in the third for a 6-1 lead.

Haase hit his first grand slam, a drive off Jake Woodford.

Pitchers injured

Milwaukee relievers DL Hall and Grant Anderson both left with injuries Thursday.

Hall looked toward the dugout and bent forward in apparent discomfort after throwing a pitch in the fifth inning. Brewers staff came to the mound to check on him before he was removed from the game.

Anderson took over for Hall but got hit in the right forearm by a liner from Bryce Eldridge in the seventh inning.

Brewers manager Pat Murphy said after the game that Hall was undergoing an MRI and that the left-hander’s subscapular and pectoral muscles were hurting. Murphy said Anderson had bruised his forearm.
