If Andrew Cashner is waiting for the right opportunity to improve a tumultuous record against the Rockies, he won't get many chances better than Wednesday night.
A battered Rockies lineup already missing two of its biggest weapons in Troy Tulowitzki and Dexter Fowler may also be without Carlos Gonzalez for the third consecutive game at Petco Park. It's against that dampened Colorado offense that Cashner will try to lower his career 9.77 ERA -- his worst mark against any club -- in seven games (two starts) against the Rockies.
San Diego ended its 10-game skid with a 2-1 victory over the Rockies Tuesday night, setting the stage for a rubber match Wednesday.
"When you get as deep as this one, there's a tendency to really press more than any other time during the course of the season," Padres manager Bud Black said after his team snapped the skid. "I felt that a little bit with some of our guys which is a natural reaction, so this was a good one."
Fortunately for the Rockies, one of their most consistent starters will take the mound in left-hander Jorge De La Rosa. De La Rosa battled a bruised thumb and a cut finger throughout June before tossing 5 1/3 innings against the D-backs without any major injury problems on Friday.
De La Rosa did surrender three runs and picked up his fifth loss, but he said he's focused on maintaining strong mechanics so the thumb issue doesn't turn into a more serious arm issue.
"I felt it a bit, but that was no excuse," De La Rosa said of how his hand held up Friday. "I made a few mistakes to a few hitters, and that cost me.
"I try to work on my mechanics all the time, trying not to get any more injuries. When I hurt my elbow, my mechanics were odd sometimes. I'm trying to stay healthy."
Padres: Ross getting ready to start
Long-inning reliever Tyson Ross will soon be back in the Padres' starting five to fill in for an injured Clayton Richard, but he's getting a Minor League tuneup first.
Ross, a member of San Diego's Opening Day rotation, made three starts in April before an injured left shoulder pushed him onto the disabled list and out of a starting job. Ross -- who lasted no more than 5 1/3 innings in his three starts -- struggled with his efficiency and had a 3.86 ERA as a starter.
He will make his first start with Triple-A Tucson Friday, scheduled to throw between 60 and 70 pitches, and will likely need at least one additional start before the Padres consider calling him back up to the big leagues.
Rockies: Colorado offense still among league's most productive
Even with Tulowitzki absent for nearly a month and Fowler playing sparingly over that stretch, the Rockies' 414 runs this year are second-most in the National League.
The Rockies scored 141 runs in the season's first month before the injury bug struck, 120 in May and 129 in June. They are well off that pace in July, with just 24 runs through eight games. The Cardinals, who have scored 440 runs, are the only NL team ahead of Colorado.
• The Rockies are 9-3 against the Padres this year, by far their best record against a division opponent. Their next-best record within the NL West is a 5-4 mark against the Dodgers.
• The Padres 10-game slide was their longest since 2010, when they also lost 10 straight games.
• Eric Stults threw a four-hit complete game against the Rockies Tuesday night, the second time he's gone the full nine innings in his last six starts.
