SAN FRANCISCO — Thairo Estrada hit a three-run homer during San Francisco’s four-run eighth inning, and the Giants beat the Brewers 5-1 on Thursday to avoid a four-game sweep.

A day after falling out of first place for the first time since May 30, the Giants (85-49) moved into a tie atop the NL West with the idle Los Angeles Dodgers. Austin Slater also connected, and Logan Webb pitched seven sparkling innings.

San Francisco had dropped four in a row.

Milwaukee (82-53) wasted a terrific performance by Eric Lauer, who tossed seven innings of three-hit ball. The NL Central leaders had won four in a row.

Darin Ruf put the Giants ahead to stay with a two-out RBI double off Devin Williams in the eighth. Estrada followed with a drive to left for his fourth homer.

Williams (7-2) got two outs and was charged with four runs. The 2020 NL Rookie of the Year allowed one unearned run over his previous 22 appearances, striking out 31 in 21 innings.
