The Athletic | Eno Sarris ($): While they’re probably not actually perfect pitchers, Luis Castillo and Jack Flaherty are models for how you’d build one: command, a variety of pitches, velocity, and a lack of injury history.
Baseball Prospectus | Rob Mains ($): The Rays technically got worse performance from their relievers than starters, which is not ideal, but that’s not entirely accurate, as they also had Openers in the mix. That means that even classifying the distinction is a faulty exercise, further blurring the lines between pitching roles.
ESPN Insider | Buster Olney ($): Corey Kluber could very well move this offseason but... where? The Yankees are the obvious candidates with their stacked farm, but another teams crop up in rumors as well: the Padres who can take another salary dump like Jason Kipnis; the Mets could add to their rotation; or, the Astros could restock their starting pitching depth.
