Raimel Tapia followed with a single in an 11-pitch at-bat and McMahon hit a three-run homer to give the Rockies the lead. A walk and three singles made it 5-2 and Tapia, who had three hits, drove home Kemp with a triple in the third.

“If we turn that double play, everything’s different. Kolby battled, came out the next inning and fought through it. But it takes you down,” Rangers manager Chris Woodward said. “When your starting pitcher has to throw 40 pitches in an inning it’s pretty much game over at that point. It was a good lesson for us. We have to finish those plays off, we have to finish these innings off, because this is what happens.”

All six runs against Allard (0-1) came with two outs, and the left-hander’s ERA jumped from 1.00 to 5.25 after his first Coors Field start.

Colorado tacked on two runs in the fourth and two more in the fifth to reach double digits for the first time this season.

“We hit a little rough patch but our team is resilient. We’re hungry and we’re still having fun,” said Kemp, who scored three runs. “The past three or four days haven’t gone as planned but we’re still right there, still in the mix.”
