LHP Jorge De La Rosa strained left groin) was placed on the 15-day disabled list. He was injured running out a ground ball in the third inning Tuesday night and left the game. In five games, De La Rosa is 1-3 with a 10.18 ERA and opponents are batting .330 against him. He had never allowed three homers in a game at Coors Field prior to this season but has done it twice this year -- on April 9 against San Diego and Tuesday against Pittsburgh. In his five starts, De La Rosa has pitched just 20 1/3 innings and has not made it through five innings in four outings. His velocity has dropped, and De La Rosa said, "I feel like my arm is kind of lazy, but I don't know what's wrong."

LHP Jorge De La Rosa strained his left groin running out a grounder in the third inning and left the game. He allowed four runs on five hits, including three homers, while walking three (one intentionally) and striking out five in three innings. In five starts, De La Rosa, who was Colorado's Opening Day starter, is 1-3 with a 10.18 ERA. He never previously allowed three homers in a game at Coors Field before doing it twice this season -- on Tuesday against Pittsburgh and on April 9 against San Diego. In 20 1/3 innings this season, De La Rosa has given up seven homers.

LHP Jorge De La Rosa's deliberate delivery contributed to five stolen bases for the Reds in the second inning alone Monday night. Holding runners aside, De La Rosa also struggled with his command, giving up four earned runs and six hits in two-plus innings. De La Rosa said he lost concentration with runners on base. Manager Walt Weiss agreed. "He was having a hard time throwing strikes and getting outs, so all of his focus went to getting the hitters out and they took advantage on the bases," said Weiss.

LHP Jorge De La Rosa will start Thursday on regular rest in the series finale against the San Francisco Giants rather than Friday at Wrigley Field against the Chicago Cubs as the Rockies juggled their rotation. Manager Walt Weiss said the change was made to keep De La Rosa on his usual schedule and have him pitch at Coors Field, where he has been successful. He has more wins than any pitcher there, going 48-17 with a 4.25 ERA. Weiss said, "I think anytime you have an opportunity to pitch 'De La' in this park, you take it." De La Rosa is looking to get on track this season, having gone 0-1 with a 12.46 ERA in two starts. In his last outing Saturday at Coors Field, De La Rosa, he threw 97 pitches in four innings against San Diego and allowed seven runs on seven hits and five runs as the Rockies lost 13-6.

LHP Jorge De La Rosa could have started Thursday on regular rest, but instead, the Rockies will use a fifth starter for the first time this season. De La Rosa is 0-1 with a 12.46 ERA in two starts, and he labored Saturday when he threw 97 pitches in four innings against the Padres, giving up seven runs on seven hits and five walks. "He didn't look like himself," manager Walt Weiss said of De La Rosa. "It looked like he was laboring right from the get-go."

LHP Jorge De La Rosa gave up eight hits and five runs in 4 2/3 innings, unable to hold a 7-1 lead long enough for the victory. He gave up two runs in the fourth and two more in the fifth before being replaced by RHP Justin Miller with two outs and the bases loaded. De La Rosa is 1-7 against the D-backs at Chase Field, with his only victory coming last year.

De La Rosa (Achilles) has been shut down for the remainder of the season, Nick Groke of the Denver Post reports.

The Rockies will go back to a traditional five-man rotation for the final weeks of the season, with both De La Rosa and Jon Gray shut down. De La Rosa was scratched from his scheduled start Wednesday due to right Achilles tendinitis, though there's been nothing to suggest the issue could affect the lefty's offseason routine. He has one year remaining on his deal with Colorado.

De La Rosa has been scratched from his scheduled start Wednesday against the Pirates with right Achilles tendinitis, the Associated Press reports.

The Rockies will call on long reliever Christian Bergman to make a spot start in De La Rosa's absence. It's not clear if De La Rosa will be available at some point later in the week or if the Rockies are planning on having him skip his turn entirely while he recovers from the injury.

De La Rosa had a rare complete game loss on Wednesday, as he allowed just two runs on six hits and a walk over eight innings in a 2-0 loss to the Dodgers. He struck out five.

Even though De La Rosa picked up a loss, he did a big favor for the Rockies by sparing their tired bullpen after a marathon 16-inning win on Tuesday. De La Rosa was simply outduelded in this matchup by a sharp Alex Wood against a tired Rockies lineup. On the other hand, De La Rosa faced the worst Dodger lineup put together all season, with no Yasiel Puig, Adrian Gonzalez, Justin Turner, Jimmy Rollins, Andre Ethier, Scott Van Slyke, or Yasmani Grandal. In any case, he'll look to continue this form against the Pirates next Tuesday.

De La Rosa gave up six hits, three earned runs and three walks in five innings in a 4-3 victory over the Padres on Thursday. He struck out six.

De La Rosa endured some rough patches, particularly against his old nemesis Matt Kemp, who reached base safely in all three at-bats against him. The veteran southpaw's control was somewhat erratic again on Thursday, coming off a two-start stretch where had only given up one free pass. De La Rosa's average of more than four walks per nine innings continues to be one of the most maddening aspects of his game for fantasy owners.

De La Rosa (9-6) gave up just one run on six hits while striking out seven in Friday's win over the Giants.

De La Rosa has a 2.64 ERA in his past six starts, lowering his season ERA from 5.03 on Aug. 1 to 4.24. The most encouraging number in De La Rosa's Friday box score, however, has to be the zero he hung up in the walks column. Somehow, De La Rosa has been able to pitch effectively over the past month while averaging over three walks per nine innings, a rate still much better than his season average. If he's able to follow up Friday's performance with further stinginess with free passes, he could become formidable down the stretch.

De La Rosa (8-6) flummoxed the Pirates in Sunday's victory, tossing six scoreless innings while striking out seven batters.

De La Rosa was only at 93 pitches before allowing a double to Aramis Ramirez to lead off the seventh, but was ejected by home-plate umpire Jeff Nelson after barking about the strike zone following the hit. In any event, it was a great effort from De La Rosa, who conceded that he didn't have his best fastball during the outing, but compensated for it by using a strong split-finger changeup to induce 13 swinging strikes and seven groundballs. The lefty has generally been a reliable streaming option all season away from Coors Field, producing a 6-4 record and 3.22 ERA in 12 road starts.

De La Rosa took his sixth loss as he allowed five runs on nine hits and four walks over seven innings Monday at Atlanta. He struck out three.

De La Rosa has now given up at least six runs in five starts this season, and this marks the second time he's done it on the road, and after giving up just four home runs in 10 previous road starts, he served up two Monday night. Still, De La Rosa has a 3.51 ERA on the road compared to a 5.91 mark at Coors Field, and with hitters slugging .477 off him there, he remains a fantasy option solely when he's away from home.

De La Rosa struck out six and worked around 10 baserunners -- four hits and six walks -- to deliver six shutout innings against Washington on Wednesday, but received no decision.

This was quite the peculiar Coors Field game -- a pitchers' duel that wasn't decided 'til the Rockies' bullpen blew it late. Well, actually that part isn't too unusual. You'll almost never see a pitcher allow so many baserunners while keeping the other team off the board in Colorado. He's gone at least six innings in four straight starts, but remains a highly risky fantasy option both at home and on the road.

De La Rosa (7-5) struck out seven and allowed just two runs in six innings Wednesday against the Mets, but took the loss. He surrendered four hits and two walks.

De La Rosa owned sparkling stats away from Coors Field before his current stretch of four consecutive road starts, and though it started with a dud -- six runs at Wrigley -- the veteran left-hander's delivered three quality starts in a row. He'll return home for a date with the Nationals next week, but De La Rosa hasn't been a good start in Colorado, where he owns a 6.62 ERA this year.

De La Rosa didn't factor into the decision after giving up four runs (three earned) over six innings in Friday's loss to the Nationals.

De La Rosa was on the hook for the loss after departing with the Rockies facing a 4-0 deficit, but Carlos Gonzalez's go-ahead grand slam in the top of the eighth inning would bail him out. It was the sixth quality start for De La Rosa in his nine road starts this season, but the left-hander still owns a rather poor 4.85 ERA and 1.40 WHIP across 104 innings this season.

De La Rosa (7-4) allowed two runs on seven hits over 6.2 innings in a win over the Cardinals on Saturday, striking out four without a walk.

The 34-year-old had given up 12 runs in just 9.2 innings over his last two outings, but bounced back with a strong performance in St. Louis. De La Rosa has been mostly solid this season, but a few horrible outings make his overall stats look less than impressive. Four of the five starts where De La Rosa has allowed at least five runs have come at Coors Field, though, so the veteran has been an underrated commodity on the road all year. The lefty takes his 3.02 road ERA to Washington for his next start Friday.

De La Rosa served up six runs on five hits over just 3.2 innings Monday against the Cubs. He struck out two and walked two.

De La Rosa has now allowed six earned runs in consecutive road start after allowing just two earned runs in his first 31.1 road innings. De La Rosa has still been much better on the road (3.04 ERA) than at Coors Field (6.64 ERA), but De La Rosa's struggles at home aren't just about the run environment. De La Rosa has just 33 strikeouts to 18 walks in 41 road innings now, peripherals that don't back up his shiny road ERA.

De La Rosa struck out eight in six innings, but gave up six runs on five hits and two walks against the Rangers on Wednesday.

That's a pretty typical Coors Field outing for you, and it highlights why despite a strikeout rate that's spiked to nearly one per inning this year, De La Rosa remains a highly risky fantasy roll at home. On the road, however, the 34-year-old lefty has an incredible 1.93 ERA in six starts this year. Fortunately, his next outing will come away from Coors, against the Cubs at Wrigley Field.
