After a heartbreaking loss in extra innings on Tuesday, the Rockies and Astros head to Denver to finish their four-game interleague series. Ryan Castellani will take the mound for the Rockies and will be looking for his first decision of the year (hopefully a win). So far in 2020, the rookie right-hander has made two starts and thus far has only given up one earned run on two hits for a nice 1.04 ERA in 8 2⁄3 innings.
He will face 26-year-old Framber Valdez — a third-year left-hander.
