Oakland A’s offense silenced in loss to Colorado Rockies

A suddenly potent Oakland Athletics offense that had no trouble scoring runs in its first two games against the Colorado Rockies at Coors Field over the weekend was silenced in Sunday’s series finale.

Ty Blach tossed five strong innings, Ryan McMahon had two hits and drove in both runs, and the Rockies beat the A’s 2-0 on Sunday to salvage the final game of the three-game set.

Matt Koch, Brent Suter and Daniel Bard each pitched an inning before Justin Lawrence capped the shutout with a clean ninth to earn his eighth save.

Ramón Laureano had two hits and Luis Medina (3-8) allowed two runs in 5 1/3 innings for the Athletics (30-77), who fell to 2-3 on their eight-game road trip that continues with a three-game series against the Dodgers in Los Angeles on Tuesday.

Oakland, which entered the weekend series averaging 3.22 runs, put up a total of 19 runs in its wins Friday and Saturday nights against traditional starters. The Athletics’ bats went silent against Blach, a reliever and designated opener, and have now been shut out 12 times this season.

Blach (1-0), making his second straight start, went a season-high five innings and threw just 11 balls in his 52 pitches. He allowed three hits and only one runner past first base.

McMahon provided the run support with an RBI single in the third inning and a two-out double in the fifth to bring home Ezequiel Tovar.

The Athletics’ best chance to score was against Suter in the seventh, when they loaded the bases with two outs. Suter got Nick Allen looking with a 78 mph changeup to end the inning.
