2025 Fantasy Outlook
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.

No-decision in quality start
Nelson did not factor into the decision in Saturday's extra-inning win over the Twins. He allowed four hits and three walks while striking out four across six scoreless innings.
Analysis
Nelson got off to a slow start by allowing four hits to the first six batters he faced, but he got out of a bases-loaded jam in the second inning and kept the Twins off the board. He generated 11 whiffs on 90 pitches (56 strikes) and was in line for his eighth win of the season, but he had to settle for the no-decision after the Twins tied the game at 2-2 in the eighth. Nelson has logged a quality start in each of his last five outings (though he has just one win to show for it), and the 27-year-old right-hander has 2.92 ERA and 1.04 WHIP across 64.2 innings in 11 starts since the All-Star break. His next start is tentatively slated for next weekend at home against the Phillies.

Past Fantasy Outlooks
2024
2023
Nelson worked as a back-end starter for Arizona in 2023, but it was an underwhelming rookie campaign with a 5.31 ERA, 1.42 WHIP and 96:46 K:BB across 144 innings. His 7.4 percent walk rate was solid and consistent with his time in the minors, but he had a 15.5 percent strikeout rate and a 1.5 HR/9. He still made the postseason roster and had a minimal role prior to the World Series, when he allowed just one run over 5.1 frames of valuable long relief in Game 4. Despite that strong finish, Nelson likely won't enter 2024 with any guarantee for a rotation spot, especially since Arizona made additions in free agency. However, the right-hander still has plenty of upside and was encouragingly less reliant on his fastball last season, and he could be a solid back-end piece in 2024 if he's able to better utilize his secondary offerings.
