Estevez (illness) was transferred to the 15-day injured list Thursday.
Estevez landed on the COVID-19 injured list Tuesday, but he doesn't actually have coronavirus, per Sonja Chen of MLB.com. Still, the ailment has affected him to the point that the Rockies decided to shut him down for the year. He'll end the season having recorded a career-best 3.47 ERA in 57 innings.
