Jorge De La Rosa, like the Rockies, has had a rough go of it lately. He'll be looking for his first win since May 27 when he takes the mound on Tuesday night against the second-place Cardinals at Coors Field.
Colorado will be attempting to snap a skid that reached seven following an 8-0 loss to St. Louis in the series opener on Monday night.
Two starts ago, the lefty De La Rosa exited the game with tightness in his lower back. In his last outing, De La Rosa never had a chance, watching as counterpart Clayton Kershaw put together one of the best pitching performances of all time.
As memorable as the no-hitter was for Kershaw, it was equally forgettable for De La Rosa, who gave up eight runs in 3 1/3 innings.
"He's fine, physically," Rockies manager Walt Weiss said. "Last outing against the Dodgers -- it almost always comes down to command, and he didn't have his 'A' command. They knocked it around a little bit.
"I always feel good with Jorge on the mound. I feel like he can shut down any lineup at any time."
De La Rosa is 6-6 this season with a 4.75 ERA.
His counterpart Tuesday, right-hander Shelby Miller, is one of many Cardinals suffering from midseason bumps and bruises. He scraped his left arm on a slide and felt a pinch in his hip during his last start.
"It was like a stinger," Miller said after that outing against the Phillies. "My mechanics just went to a mess."
Miller might be in for a wakeup call at Coors Field, having allowed 11 homers in 15 starts this season.
But in the 23-year-old Miller's lone start against the Rockies, on May 10, 2013, he twirled a shutout.
Cardinals: Kozma, Fornataro replace Garcia, Wacha
On Wednesday, Marco Gonzales will make his Major League debut for St. Louis, prompting yet another roster move.
But for now, Pete Kozma and Eric Fornatero have been recalled to help fill the void left by Jaime Garcia (left shoulder discomfort) and Michael Wacha (right shoulder stress reaction).
Fornatero provides the Cardinals with a fresh bullpen arm for what could be a high-scoring series at Coors Field. In eight appearances this month with Triple-A Memphis, the righty posted a 0.87 ERA and racked up eight saves.
The stint with the big league club could be a short one for either Fornatero or Kozma, the shortstop. One of the two might be the out man out when St. Louis makes another move to add Gonzales to the roster.
"We're going to just have to ride it out here for a little bit, see what we see, then make adjustments," said St. Louis manager Mike Matheny.
Rockies: New opportunity for Jackson Williams
On Monday, the Rockies activated Jackson Williams while catcher Michael McKenry is away from the club for three games on bereavement leave.
Williams, also a catcher, was a supplemental first-round Draft pick by the Giants in 2007. He's appeared in 310 games at the Triple-A level.
He has hit a career-best .262 this season, with two home runs and 21 RBIs.
"Getting over here and getting a little change of scenery, maybe a little change in philosophy, allowed me to take a little pressure off myself," Williams said."Glenallen Hill [the Colorado Springs manager] was a big factor in that. He's real in tune with the mental side of the game -- making sure your head is clear and you're getting the most out of yourself every single day. You try not to think about it, but when you spend three or four years in a row with the same organization in Triple-A, you start to wonder.
"One of the big things that I liked was we came into Spring Training and we got on player plans. They gave us a sheet to write down your strengths, your weaknesses, and being in tune with that, it doesn't matter what stage of your career that you're on or how old you are."
• Miller is 5-1 with a 2.55 ERA in nine career starts against the NL West.
• The Rockies are 1-6 on the season against the NL Central.
