WEST SACRAMENTO, Calif. (Interstat) — Bryan Reynolds homered twice and drove in three runs as the Pittsburgh Pirates rallied from an early four-run deficit to beat the Athletics 6-5 on Tuesday night at Sutter Health Park.

Reynolds, who went 4-for-5, delivered the decisive blow in the seventh inning with a two-run homer to right field off Athletics reliever Elvis Alvarado, erasing a 5-5 tie and giving the Pirates their first lead of the game. The left fielder also led off the sixth inning with a solo homer to center field, part of a three-hit performance that sparked Pittsburgh’s comeback.

The Athletics jumped on Pirates starter Mitch Keller in the first inning, scoring four runs on three hits and three walks. Zack Gelof delivered the big blow with a bases-loaded single that scored Nick Kurtz, Tyler Soderstrom and Jacob Wilson, and a throwing error by first baseman Spencer Horwitz allowed Gelof to advance to second. Lawrence Butler followed with a double to left field, plating Gelof for a 4-0 Athletics lead.
