The A's rode a six-game winning streak into Denver on Friday. Sunday night, they head home losers of three straight.
After scoring 41 runs in a four-game sweep in Texas, the A's scored a total of four runs in three games in Colorado.
Matt Chapman and Khris Davis provided the offense for the A's as each hit solo home runs. But it wasn't enough as the Rockies scored twice in the second inning and once more in the third.
Starter Frankie Montas failed to make it out of the fifth inning Sunday. He allowed eight hits, three earned run and two weeks in 4.1 innings. He struck out six. Yusmeiro Petit, Lou Trivino and Emilio Pagan combined for 3.2 perfect innings of relief.
The day got off to a sour note for the A's. They placed jack-of-all-trades Chad Pinder on the 10-day disabled list due to a left elbow laceration he suffered in a car accident on Saturday.
Chapman's homer was his 13th of the season. Davis' 28th homer of the season moves him with four J.D. Martinez for the American League lead.
Now, the A's return to Oakland looking to regain their swagger. T
