Mike Yastrzemski hit a go-ahead two-run homer in the seventh inning as the visiting San Francisco Giants rode the long ball to a 5-4 comeback victory over the Milwaukee Brewers on Tuesday.

With Milwaukee ahead 4-3, Matt Chapman singled to open the seventh off Brewers reliever Joel Payamps (3-6). Yastrzemski followed with his 11th homer, producing the first runs allowed by Payamps in 12 outings this month.

Willy Adames put the Brewers on top in the sixth with his team-best 24th homer. Jake Bauers walked to open the frame before Adames sent a 3-2 pitch 435 feet to left-center, chasing Giants starter Logan Webb after 110 pitches.

Webb had entered the game without allowing a home run over his last 43 1/3 innings, the longest active streak by a starting pitcher in the majors. Webb gave up four runs on four hits in five-plus innings. He walked three and struck out four.

Camilo Doval (5-1) finished the sixth for the victory, working into and out of a bases-loaded jam. Landen Roupp and Tyler Rogers combined for two scoreless innings, and Ryan Walker handled the ninth inning for his fourth save.

Grant McCray put San Francisco in front 3-2 in the fifth a one-out solo homer. One batter earlier, Blake Perkins had prevented a leadoff homer with a leaping grab above the center field wall on Thairo Estrada's drive.

Chapman brought the Giants even at 2-2 with his 21st homer, a two-out solo shot in the fourth.

Rookie Jackson Chourio put Milwaukee in front 2-1 in the third with a booming two-run homer. Brice Turang singled with one out, and Chourio drove a 2-0 pitch 449 feet to center for his 16th home run.

The Giants manufactured the game's opening run in the top of the third. McCray walked, stole second, advanced on a balk and came home on LaMonte Wade Jr.'s RBI groundout.

Milwaukee starter Tobias Myers lasted five innings and permitted three runs on three hits and a walk, with four strikeouts.

The contest was the opener of a three-game series. The Giants had lost three of their previous four games. The Brewers took their fourth defeat in six games.
