PHOENIX — Ian Kennedy matched his career high with 12 strikeouts in six innings, Jason Kubel drove in five runs and the Arizona Diamondbacks roughed up the Colorado Rockies in a 10-0 victory Tuesday night.
Gerardo Parra had a solo homer among his four hits, Aaron Hill hit a two-run shot and the Diamondbacks had a season-high 17 hits after being shut out by Colorado the night before.
Kubel also had a two-run homer and Arizona knocked Rockies starter Jeremy Guthrie (3-4) around for seven runs to give Kennedy (5-5) a rare burst of run support.
The right-hander backed up one of his best starts of the season with another solid performance, joining Randy Johnson as the only Arizona pitchers with 12 or more strikeouts in six innings or less.
The Rockies struck out 16 times overall and were shut out for the third time this season after getting 12 hits in a 4-0 win over Arizona Monday night.
Kennedy won 21 games and was fourth in NL Cy Young voting last year, firmly establishing himself as Arizona's ace. He got off to a decent start this season before a miserable May, opening the month with five losses while allowing 20 earned runs in 30 innings.
Kennedy regained form in his last start, giving up a run in 7 2-3 innings in a win over San Francisco on May 30 to end the longest losing streak of his career.
The right-hander was good again against the Rockies, striking out seven in the first three innings, including Guthrie and Dexter Fowler with runners on second and third to end the second. Kennedy kept getting Colorado's hitters to swing and miss after that, striking out 12 for third time in his career while allowing five hits.
He got some help, too.
The Diamondbacks scored four runs in Kennedy's last outing to match the total run support his previous six starts, and gave him plenty of backup again.
Hill hit his sixth homer of the season in the second inning and Kubel, swinging away on a 3-0 pitch in the third, lifted his fifth of the season to the pool deck in right for another two-run shot. Kubel added a two-run single in the fourth inning and Chris Young chased Guthrie with an infield single that drove in another run and put Arizona up 7-0.
Guthrie had felt at home on the road this season, allowing six earned runs in 24 1-3 innings in four starts away from Coors Field while going 1-2 with an 8.87 ERA in the thin air.
The right-hander surpassed his season road total for runs allowed in his first desert start, giving up seven on 11 hits in 3 1-3 innings.
Kubel added a run-scoring triple off Guillermo Moscoso in the eighth inning that just missed going out for his second homer and scored on Miguel Montero's sacrifice fly to make it 10-0.
Notes: Diamondbacks manager Kirk Gibson gave Justin Upton the night off and might not play him on Wednesday to give the right fielder a mental break. Upton is hitting .243 with four hits in his last 24 at-bats, and Gibson said he is pressing as he tries to break out of the season-long slump. ... Rockies INF Jonathan Herrera, who has been on the DL since May 23 with a strained right hamstring, will begin his rehab assignment with Double-A Tulsa on Wednesday. ... Arizona LHP Wade Miley, the starter Wednesday against Colorado, leads all rookies with six wins and a 2.72 ERA. ... Rockies LHP Josh Outman will make his second start after starting the season with eight appearances out of the bullpen.
