Josh Collmenter (ulcers) visited with a doctor Tuesday and is expected to be cleared to resume baseball-related activities within the next few days. Collmenter was likely prescribed some medication for his ulcers. He should be ready to rejoin the Diamondbacks' bullpen when first eligible on August 24.

Diamondbacks placed RHP Josh Collmenter on the 15-day disabled list, retroactive to August 9, with ulcers. No word on the severity of the issue or a timeline for his return. Collmenter has a 4.24 ERA and and 69/18 K/BB ratio over 74 1/3 innings this season as a starter and reliever. The Diamondbacks have recalled right-hander Brad Bergesen from Triple-A Reno in a corresponding roster move.

Making his first start since rejoining the Diamondbacks rotation, Josh Collmenter held the Astros to two runs on seven hits in six innings of Sunday's 8-2 win. Collmenter struck out four, walked one and allowed a solo home run to Justin Maxwell. With one relief outing sprinkled in the middle, Collmenter has now been quality in each of his past three starts, and owns a 3.82 ERA and 1.29 WHIP in 66 innings between the bullpen and rotation. He's liable to go off the tracks at any time, but Collmenter is worth an own in NL-only leagues for the time being.

Josh Collmenter is shifting back into the Diamondbacks' starting rotation to replace Trevor Bauer. Bauer was sent back to the minors this week after registering a 6.06 ERA and 17/13 K/BB ratio in his first 16 1/3 major league innings. Collmenter has posted some superb numbers out of the Arizona 'pen but should probably be avoided in most standard fantasy leagues.

Josh Collmenter notched his first win of the season after allowing two runs -- one earned -- in six innings Friday against the Dodgers. Collmenter has allowed just two earned runs in 16 innings in his three starts since returning from his bullpen exile. Trevor Bauer hasn't been very impressive in his two starts so far, so Collmenter might stay in the rotation after the break. It will probably hinge on Bauer's performance Sunday.

Josh Collmenter held the Brewers to one run on three hits in six innings Sunday, but got stuck with a no-decision in Arizona's 2-1 loss. He struck out five and walked none. Collmenter has acquitted himself well since rejoining the Diamondbacks rotation, but he still can't be counted on to fool teams on a start-to-start basis. He's back of the roster fodder in NL-only leagues. He'll get the Dodgers at home on Friday.

Josh Collmenter is back in the Arizona rotation. With Daniel Hudson facing Tommy John reconstructive elbow surgery, the D'Backs need a starter now and for the remainder of the season. Tyler Skaggs seems like the best long-term option, but Collmenter will handle the rotation vacancy through at least the All-Star break.

Making a spot start in place of Joe Saunders, Josh Collmenter allowed one run over four innings in the Diamondbacks' win over the Cubs on Friday night. Collmenter didn't last long enough to get the decision, but the Diamondbacks won 6-1. It was Collmenter's first start since April 24 and just his fourth appearance of the month. He's primarily served as a mop-up man since being sent to the bullpen, though he has been effective in that role. Since the beginning of May, he has a 1.59 ERA in 22 2/3 innings.

Josh Collmenter has been moved to the bullpen. The Diamondbacks will call up left-hander Patrick Corbin on Monday to take Collmenter's spot in the rotation. The soft-tossing right-hander registered an ugly 9.82 ERA and 1.64 WHIP in four starts (18 1/3 innings).

Josh Collmenter will make his next start Thursday against the Pirates. There was speculation Collmenter might lose his rotation spot, but it sounds like the Diamondbacks want to see a larger sample size. Wade Miley is a candidate to replace him in the short-term. Top-prospect Trevor Bauer likely isn't far off, either.
