Collmenter is considered to be among the locks to begin the year in the Diamondbacks' rotation, the Arizona Republic reports. While he continues to exceed expectations as a starter, the Diamondbacks have a large cast of prospects and young arms acquired via trade over the past nine months capable of pushing Collmenter for his rotation spot over the course of the season. Given his senior status compared to the alternatives, it would not be surprising to see Collmenter receive the Opening Day start for Arizona. Oddly enough, he's hardly guaranteed to remain in the rotation for all of 2015 if he struggles, given the aforementioned supply of younger alternatives.

Updating a previous report, Collmenter was not officially named the Diamondbacks' opening day starter, MLB.com's Steve Gilbert reports. A previous report from Fox Sports Arizona's Jack Magruder intimated that Collmenter would be Arizona's opening day starter, and that may very well end up being the case. However, nothing official has been determined, as general manager Dave Stewart just listed Collmenter first when acknowledging which starters had been penciled into the rotation for 2015. Still, the fact remains that Collmenter will be one of the first starters to take the ball for Arizona in 2015, and should offer a solid ERA and WHIP, while falling short of what fantasy owners typically look for in the strikeout department.

Collmenter will be the Diamondbacks' opening day starter, Fox Sports Arizona's Jack Magruder reports. A lot can change between now and April, but it would seem that Collmenter will be the anchor of a lackluster pitching staff in Arizona in 2015. He certainly doesn't profile as a No. 1 starter, but he has posted an ERA under 3.70 and a WHIP under 1.30 in each of the past four seasons, so he has plenty of fantasy value. Unfortunately he has had a K-rate below 17 percent in two of the past four seasons, so he's not much help in that category.

New Diamondbacks manager Chip Hale said that he views Collmenter as a starting pitcher, the Arizona Republic reports. The Diamondbacks are re-shaping their rotation, which includes a deal that will send Wade Miley to Boston. Collmenter will begin the season as the elder statesman in the Arizona rotation after tossing a career-high 179.1 innings to a 3.46 ERA last season.

Collmenter ended his season allowing one run on three hits and three strikeouts in eight innings in the Diamondbacks' 1-0 loss to the Cardinals. It was a great start, but he still managed to get the loss. He ended the season strong, allowing seven runs in his last seven starts. In that span, he went at least six innings in each start. As a result of the good finish, his ERA moved to 3.43. He finishes the season with an 11-9 record.

Collmenter continued his strong September by tossing 6.1 innings of two-run ball Monday night. Collmenter has now allowed five runs in 27.1 innings of work this month. After the big game Monday, the righty has 11 wins and a 3.57 ERA. His final start will come this weekend against the Cardinals.

Collmenter allowed two runs on seven hits, he did not walk a batter, and struck out one over eight innings of a 2-1 loss to the Giants on Tuesday night. A tough luck loss for Collmenter who locked up in a duel with Jake Peavy, facing the Giants for the second time in six days. He's allowed just four runs over his last 35.2 innings, spanning five starts, so he's obviously on a roll right now. He'll hope for better results next time out on the road against Minnesota.

Collmenter threw six shutout innings Wednesday in a no-decision versus the Giants, allowing three hits, two walks and striking out three. The Diamondbacks bullpen was knocked around by the Giants in the seventh and eight innings, undoing Collmenter's great outing. The 28-year-old has given up only two runs in his last 27.2 innings (0.66 ERA) stretching over four starts. Collmenter will face the Giants again Tuesday, this time at home.

Collmenter (10-7) shut down the Padres on Wednesday, allowing a run on five hits and two walks while striking out three over seven innings. The Padres have scored the fewest runs in the league, but Collmenter kept them off balance all night and even added an RBI to help his cause. The right-hander has given up only two runs in 21.2 innings over his last three starts. He'll try to keep it going next Wednesday in San Francisco.

Collmenter was impressive over 6.1 innings Friday night, limiting the Rockies to just one run on two hits while striking out five. Collmenter has been outstanding during his last two turns on the mound, as the big right-hander has allowed just two runs (one earned) on six hits and no walks while piling up 13 strikeouts across 14.2 innings. Collmenter will look to continue this brilliance on the bump Wednesday in San Diego.
