Collmenter will start the first game of Wednesday's doubleheader against the Diamondbacks. As expected, Collmenter will simply move back yet again after Tuesday's game was postponed due to rain. Robbie Ray will follow in the nightcap for Arizona.

Collmenter will not pitch Tuesday against the Rockies as the game has been postponed due to rain. Mother Nature will prevent the Diamondbacks and Rockies from playing Tuesday, as she did Monday. The two teams are reportedly planning to play a doubleheader Wednesday, and Collmenter will presumably start one of them for Arizona.

Collmenter is slated to start Tuesday against the Rockies, Nick Groke of The Denver Post reports. Collmenter was supposed to pitch in Monday's game but it ultimately got rained out. He shouldn't be affected by the schedule change, although it's supposed to rain in the Denver area yet again Tuesday which makes Collmenter a risky option across all formats.

Collmenter will not pitch against the Rockies on Monday as the game has been postponed to due rain. Monday's specific game will be made-up at a later date but Collmenter will likely just move his start back to Tuesday. However, rain is expected in the Denver area yet again Tuesday, making Collmenter a risky option to pursue for the second-straight day.

Collmenter allowed five hits and one unearned run to go with six strikeouts in eight innings to pick up the win over the Rockies on Wednesday. Collmenter gave up an unearned run in the first, then it was smooth sailing thereafter. At one point, Collmenter retired 12 straight. It was a sterling performance, and Collmenter will have a chance to repeat his gem Tuesday at Colorado.

Collmenter struck out three and gave up three runs on six hits over six innings Friday against Pittsburgh. He took the loss, but Collmenter pitched well enough to keep the D-backs in the game. He's rebounded nicely after a rough start on Opening Day, surrendering six earned runs over the last 20 innings. Collmenter will make his next start Wednesday against the Rockies.

Collmenter threw a shutout Friday in a win over the Giants. He gave up four hits and a walk while striking out 2 in the effort. This is really nice bounce back after sub-par efforts in his first two outings. Collmenter is never going to be a volume strikeout pitcher, but he has shown an ability to keep hitters off-balance in the majors and he should eat a lot of innings with league-average ratios at the top of the D-Backs rotation this year.

Collmenter gave up three earned runs on ten hits and a walk in five innings of work to take the loss Sunday against the Dodgers. He struck out one and gave up a home run in the contest. Collementer drops to 0-2 on the season, but more importantly he has a 6.52 ERA and 2.17 WHIP. He has yielded 19 hits in 9.7 innings and has yet to find the effectiveness he had during last year's breakout season. Collmenter's fastball velocity has been down a bit in the early going, which could be diminishing the effectiveness of his change up. Sorting that out would be a good step to righting the ship.

Collmenter pitched just 4.2 innings giving up 10 hits, five earned runs, walking one, and striking out four and took the loss Monday in a 5-4 loss to the Giants. Collmenter didn't have the deception that he showed last year and needs in order to thrive. He's going to face questions all year about whether he can repeat what he did last year, but this is just the first start of the season so there is no need to worry about Collmenter just yet. His next start is scheduled for Sunday against the Dodgers.

Collmenter will start for the Diamondbacks on Opening Day. Collmenter has been better than advertised over the past few seasons, posting a sub 3.50 ERA in each of the last two, though he spent 2013 in the bullpen. After a strong 2014 campaign in which he posted a 3.46 ERA, 1.13 WHIP and 115 strikeouts over 179.1 innings, he heads into 2015 locked into the Dbacks rotation, evidenced by his Opening Day start.
