Amid a lost season, the Rockies’ best pitcher and best position player carried Colorado to victory on Wednesday night in Oakland. Austin Gomber carved up the Athletics, throwing eight innings of one-run ball while continuing to look the part of Colorado’s ace. Then, Ryan McMahon — making a strong case for his first all-star nod — blasted the game-winning, two-run homer in the 12th for a 4-3 victory at the Oakland Coliseum. “(Gomber) was brilliant,” Rockies manager Bud Black told reporters.
