DENVER -- Colorado Rockies starter Juan Nicasio is staggering toward the end of an inconsistent and lately very disappointing season.
He shoved the Rockies into a deep early hole Sunday against the Diamondbacks, and Arizona held off Colorado's comeback attempted to win 13-9 in the rubber game of the three-game series.
Nicasio endured his second straight poor start. He departed after 2 1/3 innings, matching his shortest start of the season, and yielded seven hits and seven runs. On Tuesday against the St. Louis Cardinals, Nicasio surrendered eight hits and eight runs in 2 2/3 innings.
Nicasio was 6-4 with a 4.40 ERA in his first 19 starts. In his past 11 starts, he is 2-5 with a 7.10 ERA and has pitched six innings just three times.
He gave up four runs in the second inning and three more in the third, allowing seven hits, four of them doubles. Nicasio walked two batters, and both scored.
Gerardo Parra doubled home two runs with one out in the second, after Nicasio gave up a single and a walk to start the inning. Chris Owings followed with an RBI double, and Adam Eaton's two-out single made it 4-0.
Nicasio gave up a leadoff walk in the third to A.J. Pollock, who scored when Paul Goldschmidt doubled into the left field corner. Miguel Montero singled with one out, and Matt Davidson drove in a run with a double off the left field wall that finished Nicasio.
Jeff Francis entered and gave up a run-scoring single to Parra on his first pitch, a ball softly hit to right field, putting Arizona ahead 7-0.
Davidson, who hit a ninth-inning homer, drove in four runs. Pollock, Eaton, Parra and Aaron Hill each had three of the Diamondbacks' 19 hits.
Colorado first baseman Todd Helton, who went 3-for-5, hit two doubles, giving him 591 in his career, drove in four runs, raising his career total to 1,402 RBIs. Michael Cuddyer and Charlie Blackmon each added three of Colorado's 19 hits.
Will Harris (4-1) got two outs in the fifth inning and was credited with the win. Arizona starter Patrick Corbin gave up four runs on 10 hits in 4 1/3 innings.
NOTES: Cuddyer was back in the lineup after sitting out since leaving Thursday's game with a sore left wrist, the result of making a diving catch. He went 3-for-5 to raise his average to .334, giving him a lead over Atlanta's Chris Johnson in the National League batting race. They entered the day tied at .331, but Chris Johnson went 0-for-4 on Sunday and saw his average drop to .327. ... Manager Walt Weiss said CF Dexter Fowler (left knee) and LHP Jorge De La Rosa (left thumb) might not play the rest of the year. De La Rosa last pitched Sept. 10. Fowler, who last started Sept. 6, has been pinch-hitting but aggravated the knee while running Saturday night. ... Diamondbacks RHP Trevor Cahill will try to adjust his mechanics so he sees the ball better off the bat. On Saturday, Cahill was struck on the right hip with a line drive in the same spot where he was struck in mid-June and ended up on the disabled list for six weeks.
