Glasnow was officially called up to start Thursday's game in St. Louis.
One of the top pitching prospects in baseball, Glasnow will make his long-awaited debut against a banged up Cardinals lineup that could be without Matt Carpenter, Jhonny Peralta and Brandon Moss on Thursday. Glasnow's strikeout rates, run prevention and batting average against in the minors have been eye-popping throughout his professional career, and he should already be owned in the majority of formats. With Gerrit Cole and Jameson Taillon both expected to be activated from the DL right after the All-Star break, Glasnow's spot in the big league rotation is not guaranteed going forward, but it's hard to argue he's not one of their five most talented starters. Another issue at play is that Glasnow is about two starts away from matching last year's innings total of 109.1, so it's likely his innings will have to be managed in the second half. Still, he should find his way to at least a handful of big league starts the rest of the way, and is worth owning in all formats in the short term.
