Colorado's Drew Pomeranz and San Diego's Casey Kelly enter Saturday each with a with one Major League win under their belts and a chance to build some positive momentum as the season winds down.
Kelly is coming off a rough outing against the D-backs in which he only lasted 2 1/3 innings, allowing six runs on eight hits, including three home runs.
"I just never really got into a rhythm and I made some bad pitches," Kelly said. "My changeup got some swings and misses, but my fastball command wasn't that good and the same with my curveball."
The 22-year-old Kelly will make his fourth career start, and will be looking to emulate his Major League debut, in which he blanked the Braves in six innings.
"I think Casey wasn't as sharp as his previous two starts," Padres manager Bud Black said after his last start. "His fastball wasn't located and he was up in the zone."
Pomeranz is 1-8 with a 4.50 ERA this season, and has been ineffective against the Padres. In three starts against San Diego this season, Pomeranz is 0-3 with a 7.50 ERA, allowing 11 runs in 12 innings on 16 hits.
He will be looking to build off a solid last start in which he held the Phillies to one run in four innings, though he was pulled after throwing 77 pitches, with the Rockies' current system limiting starters to around 75 pitches.
"I felt good out there, felt like I was throwing all my pitches for strikes," Pomeranz said. "We all know going out there what we have that day. When he [Tracy] tells me I'm done, I'm done."
Padres: Quentin sits but progressing
Carlos Quentin was out of the lineup on Friday, but Black said the left fielder is continuing to make progress with his sore knee.
"Today he'll hit in the cage," Black said before Friday's game. "We'll reassess how he's doing after."
Quentin has been available to pinch-hit, but has only one at-bat in the team's last four games.
Rockies: Hernandez to have surgery on hamstring
Ramon Hernandez will have surgery on his torn hamstring tendon on Monday, and the catcher will be out for the season. He sustained the injury after hitting a ground-rule double last Monday night.
The 36-year-old Hernandez had been batting .217 in 184 at-bats this season.
Troy Tulowitzki worked out before Friday's game, and Rockies manager Jim Tracy described the shortstop as being day-to-day. Tulowitzki has been out since May 30 after having surgery to remove scar tissue from his groin, and his return remains uncertain.
With the Rockies' 7-4 win on Friday, Colorado evened the season series at 8-8. The Rockies have not lost a season series to the Padres since 2005, and the two clubs tied 9-9 in 2011.
Kelly's second career start came against the Rockies earlier this month. He did not factor in the decision, allowing seven runs (five earned) on eight hits in 5 2/3 innings.
