Manager Aaron Boone announced Sunday that Warren made the season-opening rotation and will make his first start April 1 versus Arizona, Gary Phillips of the New York Daily News reports.

The right-hander entered camp with an outside shot to earn a place in the Opening Day rotation, but long-term injuries to Luis Gil (lat) and Gerrit Cole (elbow) blew that door wide open. Warren had a good showing during spring training with a 4.19 ERA, 1.09 WHIP and 19:5 K:BB over 19.1 innings, though he did serve up three homers. Clarke Schmidt will begin the season on the IL due to a shoulder issue but may not be sidelined long, so Warren may need a strong start to the campaign in order to retain his rotation spot.

McClanahan was diagnosed with an inflamed nerve in his left triceps and will begin the season on the injured list, with manager Kevin Cash saying the diagnosis was "probably the best news that we could have heard," Ryan Bass of FanDuel Sports Network Sun reports.

The left-hander doesn't have an official timeline for his return as he begins a period of rest and recovery, but the initial diagnosis in encouraging after he exited Saturday's Grapefruit League game with the injury. A timetable for McClanahan's season debut could come into focus once he resumes a throwing program, but it appears he won't require as significant an absence as first anticipated.

Nelson will begin the season working out of the bullpen, as Brandon Pfaadt was named Arizona's No. 5 starter Sunday, Nick Piecoro of The Arizona Republic reports.

Nelson surrendered 10 earned runs across 11 innings during spring training, though nine of those runs were given up in a single appearance. The 27-year-old started in 25 of his 28 appearances for the Diamondbacks last season and had a 4.24 ERA and 126:34 K:BB over 150.2 innings.

Montgomery will begin the season as a reliever after Brandon Pfaadt was named Arizona's No. 5 starter Sunday, Nick Piecoro of The Arizona Republic reports.

Montgomery made just two Cactus League appearances and surrendered five runs over three innings, so it's hardly a surprise Pfaadt won the job battle. The Diamondbacks are likely still looking to trade Montgomery, but his 6.23 ERA over 117 innings last year and $22.5 million salary leave limited suitors.

Pfaadt will begin the season in the Diamondbacks' rotation and is scheduled to start Saturday against the Cubs, Jack Sommers of SI.com reports.

The right-hander will slot in for Arizona's third game of the season after producing a 3.18 ERA over 11.1 innings during spring training. Pfaadt had a 4.71 ERA, 1.24 WHIP and 185:42 K:BB in 32 starts for the Diamondbacks last season, though a 3.60 FIP provides a more encouraging outlook on his performance.

Burnes is scheduled to make his first start of the regular season April 1 against the Yankees, Jack Sommers of SI.com reports.

It was only a mild surprise that Zac Gallen was named the Diamondbacks' Opening Day starter for Thursday's matchup with the Cubs, but the fact that Burnes won't start until the fifth game of the season is significantly more notable. The right-hander inked a six-year, $210 million contract with Arizona in November, but the organization apparently wants to give him a few extra days after the end of camp before sending him to the mound for his team debut. Burnes was dominant in his first five spring starts before being tagged for eight runs Friday versus the Brewers while having trouble with his cutter, though there's been no indication that outing is related to his positioning in the rotation.

The Diamondbacks placed Walston (elbow) on the 60-day injured list Sunday.

It was announced in mid-March that Walston will require Tommy John surgery, so it was only a matter of time before he was shifted to the 60-day IL. The left-hander will miss the entirety of this season and isn't likely to be back until midseason of the 2026 campaign.

Manager Rob Thomson said Sunday that Walker will be included in Philadelphia's season-opening rotation, Matt Gelb of The Athletic reports.

The veteran right-hander entered camp with the expectation of working as a reliever, but instead he's needed in the rotation with Ranger Suarez (back) headed to the injured list. Walker had a 6.92 ERA and 6:3 K:BB through 13 innings during spring training, and he fared even worse in 19 appearances during the 2024 regular season with a 7.10 ERA, 1.72 WHIP and 58:37 K:BB over 83.2 innings.

Manager Rob Thomson said Sunday that Suarez (back) will begin the season on the injured list, Matt Gelb of The Athletic reports.

The left-hander suffered a back injury last week and will be unavailable for at least the first couple weeks of the regular season. Taijuan Walker will step into Philadelphia's rotation while Suarez is sidelined.

Woodford exercised the opt-out in his minor-league contract and was released by the Rockies on Sunday.

Woodford signed a minor-league contract with Colorado in mid-January and pitched in seven exhibition games, posting a 5.25 ERA, 1.33 WHIP and 6:4 K:BB over 12 innings. The veteran righty didn't appear set to make the Opening Day roster, and he'll look elsewhere for his next big-league opportunity. Woodford recorded a 7.97 ERA and 26:9 K:BB over 35 innings between the White Sox and Pirates last year, and he may need to accept another minor-league contract in order to be able to land with a new organization.
