2026 Fantasy Outlook
Despite being the team's most consistent starter in 2024, Nelson was shifted to the bullpen in 2025 to make room for free agent Corbin Burnes. How fitting that Burnes' elbow surgery (and Tommy John surgery) got Nelson back into the rotation. The right-hander was a top pitcher on the staff for a second consecutive season. In 23 starts, Nelson pitched 128 innings with a 3.16 ERA and 1.08 WHIP. Arizona will commit to Nelson in the rotation to start 2026, as Burnes will be unavailable until at least the second half, and Zac Gallen rejected a qualifying offer. While Nelson's performed well as a starter the last two seasons, there are some warning signs. He's heavily reliant on his four-seamer (61.7 percent usage) and defense dependent (7.7 K/9). The next highest pitch was his cutter (12.2 percent). If he continues to locate the fastball (+23 Run Value), limit walks, and mix in more of the secondary offerings, Nelson could become more than a mid-rotation starter. Read Past Outlooks
Signed a one-year, $3 million contract with the Diamondbacks in January of 2026.
Works four innings
Nelson allowed one run on four hits and one walk while striking out six over four innings in Monday's spring start against the Reds.
Analysis
Nelson upped his pitch count to 66 (39 strikes) in his fourth Cactus League start and will get one more outing in before the regular season. He sports a 4.50 ERA with 16 strikeouts and just two walks over 12 innings. Arizona manager Torey Lovullo hasn't set his rotation for the regular season beyond Zac Gallen on Opening Day, but Nelson should be among the top three.

Past Fantasy Outlooks
2025
2024
2023
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.

Latest Fantasy Rumors
Extension candidate?
Nelson is entering his first year of arbitration eligibility, which could prompt the Diamondbacks to pursue a contract extension, reports Jack Sommers of SI.com.
Analysis
The right-hander opened 2025 in a long-relief role but ended up starting in 23 of his 33 appearances since Corbin Burnes required Tommy John surgery in June. Nelson solidified his place in the rotation and finished the campaign with a 3.39 ERA, 1.07 WHIP and 132:41 K:BB across 154 innings. He's projected to make about $2.4 million in his first season of arbitration eligibility, per Jack Sommers of SI.com, but Arizona could instead look to secure his services long-term.
