Gelof went 1-for-3 with an RBI sacrifice fly, a stolen base and a run in a win over the Rangers on Tuesday.
Gelof snapped a 3-3 tie in the sixth inning with his sacrifice fly, which plated Shea Langeliers. He eventually scored the game-winning run on Jacob Wilson's walk-off single in the penultimate night game for the Athletics at Oakland Coliseum. The eventful night was an extension of a productive all-around month for Gelof despite some persistent contact issues, as he's generated a .278 average, .715 OPS, eight extra-base hits, seven RBI, five steals and nine runs across 84 September plate appearances.
