LAS VEGAS — Carlos Cortes and Lawrence Butler hit towering home runs in the seventh inning to rally the Athletics to a 4-3 victory over the Milwaukee Brewers on Wednesday night and win the series.

The A’s took two of three at Las Vegas Ballpark, home to their Triple-A affiliate. They are playing this week before their future fans as a stadium is scheduled to open on the Strip in 2028.

The A’s had already set the franchise record for a three-game series with 12 homers before this game and then added three more. That included one from Alika Williams, who had his first career home run with a solo shot in the sixth.

Then in the seventh, Cortes hit a 461-foot solo shot to right-center field and Butler followed two batters later with a two-run homer that traveled 463 feet to center. Both came off Chad Patrick (3-3).

Five A’s relievers shut out the Brewers over the final five innings, with Scott Barlow (2-0) getting the win and Elvis Alvarado his first save.

Milwaukee starter Brandon Sproat allowed four hits and a run over six innings and exited with a 3-1 lead.

Gary Sanchez smashed a 466-foot solo home run in the second inning for the Brewers. Jackson Chourio also homered for a 3-0 lead.

The Athletics’ Nick Kurtz’s three-game homer streak ended, but Zack Gelof extended his hitting streak to 15 games.
