Player Outlook
Ryne Nelson's improved strike-throwing ability in spring training earned him a spot in the Diamondbacks' rotation in 2024. He maintained that skill into the regular season and finished with 10 wins and the second-most innings among Arizona starters. The 26-year-old right-hander upped his strikeout rate to 20.0 percent (from 15.5 in 2023), moving from the sixth percentile to the 26th. An already good walk rate got better, while he shaved one run off his ERA (5.31 to 4.24) and cut down on home runs. In a promising sign, Nelson's performance improved deeper into the season, posting a 3.23 ERA and 28.7 K% over the second half. Still very much a two-pitch pitcher (fastballs and cutters), developing a third pitch might continue the righty's upward trajectory. There was enough development in his performance last year that he should not need to compete for a rotation spot in 2025, but Arizona signed free agent Corbin Burnes, which could push Nelson to the bullpen.

  • Diamondbacks' Ryne Nelson: Long arm in bullpen

    Rotowire
    Nelson will remain stretched out as a reliever, Alex Weiner of Arizona Sports reports. "(Nelson) is going to be able to provide us some length," Arizona manager Torey Lovullo said. "We feel like we've got some solid backup there just in case the starter doesn't give us what he needs to." Nelson, who fell short in his bid to be the No. 5 starter, became the top long option out the bullpen following the news that Jordan Montgomery will undergo Tommy John elbow surgery. The Montgomery news also suggests that Nelson could be in line to start should a current member of the rotation require extended downtime due to injury. Nelson was a valued part of the rotation in 2024, when he improved in several underlying metrics (K:BB, K/9, BB/9, HR/9) compared to 2023.

  • Diamondbacks' Ryne Nelson: Rotation bid falls short

    Rotowire
    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.

  • Diamondbacks' Ryne Nelson: Calm spring no longer

    Rotowire
    Nelson allowed nine runs (eight earned) on 11 hits while striking out one over three-plus innings in Monday's Cactus League start against Kansas City. Nelson's uneventful spring blew up in his fourth spring outing (third start). He was responsible for runs in all innings pitched and was chased after giving up four consecutive hits to lead off the fourth. The Royals were jumping on Nelson early in counts -- the right-hander threw just 55 pitches despite facing 19 batters. Nelson, who was a rotation regular in 2024, is competing for the fifth spot this spring.

  • Diamondbacks' Ryne Nelson: Makes second spring start

    Rotowire
    Nelson allowed one run on three hits while striking out three over 2.1 innings in Thursday's spring start against the Guardians. Nelson toed the rubber for a second Cactus League start and worked up to 51 pitches (30 strikes). The battle for the final rotation spot kicked into high gear this week. Nelson followed Brandon Pfaadt, who started Wednesday, and Jordan Montgomery (finger) will make his spring debut Friday in what is expected to be a multi-inning relief appearance.

  • Diamondbacks' Ryne Nelson: Logs two innings Friday

    Rotowire
    Nelson allowed one hit and two walks while striking out one over two scoreless innings in Friday's spring game against Kansas City. Nelson, making his Cactus League debut, followed starter Merrill Kelly, pitching the third and fourth innings. Nelson was a mainstay in the rotation the last two seasons -- and showed improvement in 2024 -- but he enters the spring in a battle for a rotation spot for a third consecutive season. His scoreless outing follows a similar one Thursday from Brandon Pfaadt, who is also competing for the same rotation spot along with Jordan Montgomery.

  • Diamondbacks' Ryne Nelson: Has minor-league options

    Rotowire
    Nelson still has minor-league options remaining and could open the season at Triple-A Reno, Mark Feinsand of MLB.com reports. Arizona has seven legitimate starters in camp competing for five spots. For Nelson, who was second among starters in innings pitched in 2024, to not have a spot on lock seems odd, but the Diamondbacks have assembled plenty of rotation depth. Zac Gallen, Corbin Burnes, Merrill Kelly and Eduardo Rodriguez are set in the top four spots, with the fifth starter role coming down to Nelson, Brandon Pfaadt or Jordan Montgomery. Nelson and Pfaadt, who also has minor-league options left and led the Diamondbacks in innings in 2024, could start the year in the Aces' rotation, although Montgomery is a candidate to shift to a long-relief role.

  • Diamondbacks' Ryne Nelson: Reinstated from IL

    Rotowire
    The Diamondbacks reinstated Nelson (shoulder) from the 15-day injured list Thursday, Alex Weiner of ArizonaSports.com reports Nelson threw 28 pitches in his second bullpen session Tuesday following his first session of 16 pitches. With his return coming near the close of the season, it seems Nelson will be used as a multi-inning reliever, but it is possible he may return as a starter. Yilber Diaz and Blake Walston were both optioned to Triple-A Reno on Thursday as part of a corresponding move.

  • Diamondbacks' Ryne Nelson: Throws side session

    Rotowire
    Nelson (shoulder) threw 28 pitches in a bullpen session Tuesday, MLB.com reports. Nelson has now completed two side sessions since landing on the injured list, after the right-hander previously threw a 16-pitch session Saturday. Diamondbacks manager Torey Lovullo said the team is undecided about whether Nelson could return to the starting rotation or be used as a multi-inning reliever once he makes his way back from the IL. With four games left in the regular season, the bullpen is probably a more realistic landing spot for Nelson if he gets activated.

  • Diamondbacks' Ryne Nelson: Throwing bullpen Saturday

    Rotowire
    Nelson (shoulder) will throw a bullpen session Saturday, Nick Piecoro of The Arizona Republic reports. Nelson has been on the injured list since last Saturday due to shoulder inflammation. The fact he's been cleared to return to a mound after just a week on the IL bodes well for his chances of being activated after a minimum-length stay, but he still has a few more boxes to check before the D-backs can pencil him back into their rotation.

  • Diamondbacks' Ryne Nelson: Lands on injured list

    Rotowire
    The Diamondbacks placed Nelson on the 15-day injured list Saturday with right shoulder inflammation, Jesse Friedman of GoPHNX.com reports. Nelson surrendered five earned runs over just 4.2 innings during his most recent outing Sunday, and his shoulder troubles may help explain his poor performance. The Diamondbacks are hopeful he'll be able to return to the rotation after a minimum-length stay on the injured list, though he won't be eligible for activation until the final series of the regular season. Until Nelson is back in the fold, Arizona will likely move Jordan Montgomery from the bullpen back into the rotation.

  • Diamondbacks' Ryne Nelson: Fades in fifth frame

    Rotowire
    Nelson did not factor into the decision in Sunday's win over the Astros, allowing five runs on six hits and two walks while striking out four over 4.2 innings. Nelson was handed an eight-run lead through three frames and kept the Astros scoreless until Alex Bregman took him deep in the fourth for a two-run blast. He ran into more trouble in the fifth, leading to three more runs for the Astros and was pulled one out shy of being able to qualify for the win. Sunday's outing ended a streak of five straight quality starts for Nelson and was his first time allowing five runs since June 26. He now sits at a 4.33 ERA, 1.27 WHIP and 125:34 K:BB in 147.2 innings and lines up for a start against the Brewers at home over the weekend.

  • Diamondbacks' Ryne Nelson: Racks up nine strikeouts in win

    Rotowire
    Nelson (10-6) got the win over the Giants on Tuesday, allowing two runs on four hits and two walks while striking out nine over 6.2 innings. The Giants scratched across a run against Nelson in the first and scored once more in the sixth with a solo home run by Matt Chapman. Nelson otherwise continued his brilliant run of starts, posting a fifth straight quality outing and the ninth over his last 11 starts while tying his season high with nine strikeouts. Since July 2, he holds a 2.76 ERA, 0.97 WHIP and 75:14 K:BB in 75 innings. Before then, Nelson was sporting a 5.69 ERA and 1.57 WHIP in 14 starts. He'll look to keep rolling in a projected road start against the Astros this weekend.

  • Diamondbacks' Ryne Nelson: Another quality start Thursday

    Rotowire
    Nelson didn't factor into the decision Thursday against the Mets, allowing two runs on eight hits over 6.1 innings. He struck out four. The only damage against Nelson came on a pair of solo home runs, a Pete Alonso blast in the second inning and a Francisco Lindor shot to lead off the sixth. It's the fourth straight quality start for Nelson, who's pitched to a 2.76 ERA in his last 11 outings (68.1 innings) to solidify his spot in Arizona's rotation. Overall, the 26-year-old right-hander is 9-6 with a 4.22 ERA, 1.28 WHIP and 112:30 K:BB across 136.1 innings this season. Nelson currently lines up to face the Giants on the road in his next start.

  • Diamondbacks' Ryne Nelson: Picks up ninth win

    Rotowire
    Nelson (9-6) got the win over the Red Sox on Friday, allowing two runs on five hits and a walk while striking out seven over six innings. Nelson was impressive once again, picking up his third consecutive quality start. He has looked great since the beginning of July, pitching to a 2.76 ERA with a 0.95 WHIP over his last 10 outings. The 26-year-old has struck out at least five batters eight times and has six quality starts without a loss in that span. He's next scheduled for a home start against the Mets.

  • Diamondbacks' Ryne Nelson: Remaining in rotation

    Rotowire
    Nelson will remain in the Arizona rotation moving forward with the Diamondbacks electing to move Jordan Montgomery to the bullpen, John Gambadoro of Arizona Sports 98.7 FM reports. Arizona is going back to a standard five-man rotation and will shift the struggling veteran Montgomery to relief rather than Nelson, who has posted a 2.73 ERA and 55:11 K:BB over 56 innings since the beginning of July. Nelson will start Friday's series opener in Boston.

  • Diamondbacks' Ryne Nelson: Likely to start again Friday

    Rotowire
    Diamondbacks manager Torey Lovullo said Wednesday that Nelson is tentatively scheduled to start Friday's game against the Red Sox, Steve Gilbert of MLB.com reports. Nelson will be available in relief Wednesday in Miami, if needed, but the Diamondbacks seemingly prefer to stay away from him so that he can take the hill Friday. Though Lovullo has previously stated that Arizona eventually plans to condense to a five-man rotation, Nelson has made it tough on the Diamondbacks to demote him to the bullpen. He's posted a 2.73 ERA and 55:11 K:BB over 56 innings since the beginning of July, and another strong outing Friday could prompt Arizona to keep him in the fold for another turn through the rotation.

  • Diamondbacks' Ryne Nelson: Getting start Friday

    Rotowire
    Nelson is slated to start Friday's game against the Rays at Tropicana Field. Manager Torey Lovullo said earlier in the week that Nelson would be available out of the bullpen for Wednesday's game against the Rockies, but with the Diamondbacks not needing to use the right-hander in that contest, he'll slot back into the rotation Friday for his 21st start of the season. Lovullo noted that the Diamondbacks intend to scale back their rotation from six to five men following Friday's contest, so barring another starting pitcher falling victim to an injury, Nelson looks like he'll be headed back to the bullpen after his start versus the Rays.

  • Diamondbacks' Ryne Nelson: Could be shifted to bullpen

    Rotowire
    Diamondbacks manager Torey Lovullo said Monday that Nelson will be available out of the bullpen for Wednesday's game versus the Rockies, Jesse Friedman of GoPHNX.com reports. Nelson will be ready in case starter Jordan Montgomery is unable to work deep into Wednesday's outing. If Nelson is not needed Wednesday, he will start Friday in Tampa Bay. If Nelson does in fact start Friday, it could be his last one for a while, as Lovullo says the club would then go back to a five-man rotation. Lovullo wouldn't commit to Nelson being the one to lose his rotation spot when that time arrives, but he looks to be the most likely candidate. Nelson holds a 2.90 ERA and 49:11 K:BB over 49.2 innings since the beginning of July, so he certainly doesn't deserve a demotion. However, he could be the team's starter most equipped to handle a shift to relief.

  • Diamondbacks' Ryne Nelson: Brilliant in win over Nationals

    Rotowire
    Nelson (8-6) got the win over the Nationals on Tuesday, allowing two hits and two walks while striking out nine over seven scoreless innings. Nelson was staked an 11-0 lead by the end of the third inning but never let up one bit. Both his nine strikeouts and seven innings pitched tied season highs and it was his second outing of the season of at least five scoreless frames. He gave up one run or fewer of four of his six starts in July, leading to a 2.41 ERA and .211 BAA. He also went at least five innings in every start, which is something he's wasn't able to do earlier in the season. The 26-year-old now owns a 4.53 ERA, 1.36 WHIP and 79:26 K:BB in 105.1 innings and will look to keep rolling against the Pirates to begin next week.

  • Diamondbacks' Ryne Nelson: Struggles in no-decision

    Rotowire
    Nelson did not factor into the decision in a win over the Royals on Wednesday, allowing four runs on nine hits and two walks over six innings while striking out two. Nelson got knocked around throughout the contest, allowing multiple baserunners in five of his six innings of work. Three of the four runs he was charged with came across in the fourth after the right-hander surrendered a leadoff double to Michael Massey to open the frame before allowing him to advance to third on a wild pitch. Nelson had not permitted more than three runs in any of his previous four starts this month, while his two strikeouts marked his lowest total since June 20 against Washington. He still holds a 2.97 ERA in July after Wednesday's start and hasn't suffered a loss since June 26 against Minnesota.
