The Diamondbacks have exercised Kelly's $5.25 million club option for 2022, Nick Piecoro of the Arizona Republic reports.
Kelly was limited to five games during the shortened 2020 campaign, but he made 27 starts in 2021 and posted a 4.44 ERA, 1.29 WHIP and 130:41 K:BB across 158 innings. The 33-year-old should enter spring training with a secure spot in Arizona's 2022 starting rotation.
