Collmenter (shoulder) will start Tuesday for Triple-A Reno, Steve Gilbert of MLB.com reports.

EDGE Analysis

Collmenter has struggled in his last two rehab starts with High-A Visalia as he posted a 12.27 ERA and 10.57 ERA in those outings, respectively. Diamondbacks manager Chip Hale commented that Collmenter "needs to show some positive results" in his upcoming rehab start if he hopes to return to Arizona's 40-man roster. If the 30-year-old can in fact produce a good start for Reno on Tuesday, it might be enough for him to receive a promotion by week's end.

Collmenter (shoulder) will make another rehab appearance on Thursday, Jody Jackson of Fox Sports Arizona reports.

EDGE Analysis

Collmenter has pitched a total of 3.2 innings in two games for Single-A Visalia, allowing seven hits and five earned runs. Despite the struggles, he is likely nearing a return to the MLB roster, and he will give the Diamondbacks a solid long relief option.

Collmenter is expected to return sometime in the middle of the team's upcoming nine-game road trip, Scott Bordow of the Arizona Republic reports.

EDGE Analysis

Collmenter will pitch three innings for Single-A Visalia on Monday, then the team will likely want him to make one more rehab appearance before rejoining the big league roster. When he returns, Collmenter will give the Diamondbacks an experienced long relief option out of the bullpen.

Collmenter (shoulder) will pitch twice in extended spring training and then plans to pitch three innings in a rehab start with Class-A Visalia on May 2, Jesse Sanchez of MLB.com reports.

EDGE Analysis

It appears that Collmenter is progressing well in his rehab. He was expected to pitch in some games this week, but this is the first firm timetable for his rehab process. If everything goes as planned, the right-hander could rejoin the Diamondbacks at some point during their next road trip which begins May 3 in Miami.

Manager Chip Hale said that Collmenter (shoulder) could return in early-May, Steve Gilbert of MLB.com reports.

EDGE Analysis

Collmenter has made good progress in his rehab process over the past week and now seems close to returning because of it. Hale said that the right-hander will pitch in games next week, build up his inning count, and then rejoin the Diamondbacks. If everything goes as planned, Collmenter should slot back into the Arizona bullpen as a long reliever, a role that the Diamondbacks desperately need at the moment.

Collementer remains without a timetable for rehabbing his injured shoulder, Jesse Sanchez of MLB.com reports.

EDGE Analysis

Collmenter hasn't pitched since late March, and it appears that he's made no significant progress in his recovery process. This could push his return to the Arizona bullpen to the end of the month or even early-May depending on when he begins his rehab program, but Collmenter's situation should become clearer when he begins rehabbing his shoulder.

Collmenter (shoulder) will start the season on the disabled list, Steve Gilbert of MLB.com reports.

EDGE Analysis

Collmenter was shelled across his eight appearances this spring, registering a 9.69 ERA while giving up five home runs and striking out just six batters in 13.0 innings. However, he reported some tightness in his shoulder following his last outing and although tests came back clean, he'll still start the season on the disabled list. Manager Chip Hale said Thursday that Collmenter could return to the mound within the coming days, indicating that Collmenter's injury may not be as serious as once feared, but he'll likely be at extended spring training when the season gets underway. Collmenter figures to be officially placed on the disabled list when the Diamonbacks release their official Opening Day roster Saturday.

Manager Chip Hale said that Collmenter (shoulder) is not expected to pitch in the next few days, which makes a disabled list stint to start the season more likely, Steve Gilbert of MLB.com reports.

EDGE Analysis

Collmenter was expected to make the big league roster despite having a rough spring, but more and more signs are pointing toward the right-hander missing some time thanks to this shoulder issue. Although all tests came back clean on his shoulder, Collmenter will likely not be available for the Diamondbacks until later in April.

Collmenter (shoulder) may start the season on the DL, Steve Gilbert of MLB.com reports.

EDGE Analysis

Tests were clean after Collmenter reported some tightness in his shoulder during his last spring outing, but the injury may still force the right-hander to the disabled list. Collmenter was expected to make the Opening Day roster before the shoulder issue popped up, as manager Chip Hale suggested he was willing to overlook Collmenter's spring struggles in favor of experience.

Collmenter will likely make the Opening Day roster despite a 9.69 ERA over 13.0 innings this spring, Scott Bordow of the Arizona Republic reports.

EDGE Analysis

Diamondbacks manager Chip Hale said Collmenter's big league experience "means probably everything right now." The righty was Arizona's Opening Day starter last year but found success after shifting to the bullpen, posting a 2.03 ERA. He provides the team with an option for long relief and the occasional spot start.
