2019 Fantasy Outlook
Kelly signed with Arizona and will get a chance to win a spot in the starting rotation after three seasons playing in South Korea's top professional league. An eighth-round draft pick by Tampa Bay, he got as far as Triple-A, where he had a 2.76 ERA and 8.5 K/9 in 2014, before going overseas. Kelly thrived in the KBO with a 3.80 ERA in four seasons while leading the SK Wyverns to the 2017 championship. His 4.09 ERA from 2017 doesn't look great, but it ranked in the top 10 in a hitter-friendly league, and he had a 9.0 K/9 with outstanding control (2.1 BB/9). Kelly says his velocity improved while in South Korea to the low-90s from the high-80s while in Triple-A. He'll be trying to make a unique transition as few players have moved to Major League Baseball from the KOB, and he's also doing so without any major-league experience. He's a fantasy baseball wild card. Read Past Outlooks

August 25, 2019
Kelly will remain in Arizona's starting rotation moving forward, Zach Buchanan of The Athletic reports.
Kelly's spot in the Diamondbacks' rotation was reportedly in jeopardy after he surrendered six runs over 4.1 innings Friday night against the Brewers, but after Sunday's series finale, skipper Torey Lovullo stated that Kelly's place in the rotation is safe for now. He's on track to make his next start Thursday against the Dodgers.
