The Arizona Diamondbacks are set to face the St. Louis Cardinals at Chase Field, with game time scheduled for 1:10 p.m. on Cox Ch. 34. The pitching matchup features Diamondbacks' right-hander Merrill Kelly (8-5, 3.34 ERA) against Cardinals' right-hander Miles Mikolas (5-6, 4.94 ERA). Kelly is coming off a solid performance, allowing just one run over five innings against the Angels, showcasing his effectiveness with a cutter that has limited opponents to a .129 batting average. Mikolas also comes off a strong outing, throwing 5 2/3 scoreless innings against the Nationals, and has shown promise against the Diamondbacks in previous matchups, particularly against Eugenio Suarez, who has had success against him.

Looking ahead, the Diamondbacks will start Zac Gallen against the Astros on July 21, followed by Eduardo Rodriguez, and then Brandon Pfaadt before closing the series. Gallen's performance will be crucial as he seeks to improve his win-loss record this season.
