LEADING OFF: Burnes returns, Mariners bring up big prospects

Milwaukee Brewers ace Corbin Burnes is set to face St. Louis on Thursday in his first start since testing positive for the coronavirus last month. The right-hander is 2-2 with a 1.53 ERA, 49 strikeouts and no walks in 29 1/3 innings, but hasn’t pitched since April 26. Burnes confirmed Wednesday that he had COVID-19 but said he was asymptomatic. He is scheduled to pitch against Cardinals ace Jack Flaherty, who is 6-0. Meanwhile, the Seattle Mariners are calling up touted prospects Jarred Kelenic and Logan Gilbert for their series opener at home against Cleveland, and the Kansas City Royals try to stop a 10-game losing streak when they play at Detroit.
