The Oakland Athletics had a strong offense in their first two games against the Colorado Rockies, but were unable to score in the series finale on Sunday. The Rockies won the game 2-0, with Ty Blach pitching five strong innings and Ryan McMahon driving in both runs. Matt Koch, Brent Suter, Daniel Bard, and Justin Lawrence combined to pitch a shutout for the Rockies. Despite the loss, there were some positives for the A’s. Ramón Laureano had two hits and Luis Medina showed his growth as a pitcher, allowing two runs and striking out six in 5 1/3 innings. Prior to Sunday, Medina had a 2.84 ERA and held opponents to a .207 batting average over his last six games. A’s manager Mark Kotsay praised Medina’s performance and development. The A’s pitching staff, which had the worst ERA in MLB prior to Sunday, performed well in the series, allowing only 10 runs. Kotsay emphasized the team’s competitiveness and the significance of winning the series against the Rockies. However, the A’s offense remains inconsistent. After scoring 19 runs in their previous two wins, they were shut out by Blach and have now been shut out 12 times this season. McMahon provided the run support for the Rockies with an RBI single and a two-out double. The A’s had a chance to score in the seventh inning, but Suter struck out Nick Allen to end the inning.
