2025 Fantasy Outlook
Before an early shoulder injury sidelined Kelly from mid-April to August, the right-hander was headed for a second consecutive impressive season, posting a 2.19 ERA over four starts. He had less success (4.96 ERA) following his return, but most of the damage was in August, and Kelly was back on form in September. Kelly finished with a greater HR/9 and struck out fewer batters in 2024, but when a pitcher misses four months, one should resist making judgments based on ratios/results and instead focus on the injury, which altered his pitch mix. Kelly threw more cutters and changeups than four-seamers for the first time in his career; however, he pitched well when healthy in April and September, putting him on a path for a normal winter of preparation. The Diamondbacks have confidence that the 36-year-old will return to his 2023 iteration (3.29 ERA, 9.5 K/9) and picked up his option. Read Past Outlooks

Cruises to 10th win
Kelly (10-7) tossed seven scoreless frames while allowing four hits and two walks to pick up the win Sunday against the Guardians. He struck out eight.
Analysis
The veteran righty was masterful in this 96-pitch appearance to notch his third consecutive quality start, as he limited the Cleveland lineup to just four singles. Kelly has been dependable since joining the Rangers at the trade deadline, pitching to a 3.10 ERA, 1.03 WHIP and 26:8 K:BB across 29 frames. In 157.2 total innings with Texas and Arizona, the 36-year-old now sports a 3.20 ERA, 1.05 WHIP and 147:46 K:BB while tallying 16 quality starts. The free-agent-to-be is currently scheduled to make his next start on the road at the Athletics next weekend.

Past Fantasy Outlooks
2024
2023
2022
2021
2020
2019
Kelly's ratios were nearly equivalent to his breakthrough 2022 season, but he took a different path to get there. Last season, Kelly fanned a career best 25.9 percent of batters he faced, but he also walked them at a 9.6 percent clip, the highest mark of his career. However, the 16.3 percent K-BB% was his best in a full season. Kelly didn't change his pitch mix much, other than throwing a slider a bit and it was effective. His changeup was offering chiefly driving the increase in strikeouts. Despite posting strong ratios in 2022, Kelly wasn't trusted since he didn't miss many bats. Fast forward a year and Kelly is no longer a secret after fanning well more than a batter an inning and enjoying a strong playoff run. He's likely going to be drafted around 100 picks earlier this season, which puts him in risky territory, since that assumes Kelly continues to punch out hitters at the same rate. Don't shy away from Kelly, but don't expect a repeat of last season's newfound dominance.
