Rockies' Tyler Chatwood struggles in return from DL in 9-4 loss

Tyler Chatwood allowed five earned runs on seven hits in five innings in the Colorado Rockies' 9-4 loss to the Arizona Diamondbacks on Saturday night at Coors Field.

The D-backs scored early and often against Chatwood, who was activated from the disabled list on Friday and made his first start since Aug. 14. Chris Owings plated a run on an RBI single in the second inning after Rox catcher Tom Murphy's passed ball allowed a runner to advance into scoring position. Arizona piled on with five more runs in the third, when Welington Castillo unleashed a bases-clearing double and Jake Lamb followed with a two-run homer.

The Rockies tried to crawl back over the next few innings. Gerardo Parra hit a solo homer in the bottom of the third and Daniel Descalso, who entered the series with only one Coors Field homer as a Rockie, hit his second dinger in as many nights to cut the initial six-run deficit in half.

D-backs starter Braden Shipley helped his own cause with an RBI groundout in the top of the sixth before Murphy made up for his earlier gaffe with a run-scoring single in the bottom half of the inning. That was all the scoring the Rockies would do, though, while the D-backs added a couple of runs against relievers Christian Bergman and Jake McGee.

Rockies prospect Raimel Tapia in his first career start had two hits, as did Parra. DJ LeMahieu led Colorado's offense with three knocks to raise his National League-leading batting average to .345.

The Rox (65-70) on Sunday will go for their third consecutive series victory -- and fifth in their last six -- with Jon Gray on the hill opposite Archie Bradley.
