Pitcher Notes: Rays, Glasnow, Mets, Wacha, Cardinals, Flaherty

While recovering from November wrist surgery, Tyler Glasnow is tinkering with his arsenal. The big right-hander plans on ditching his changeup and replacing it with a splitter, tweets MLB.com’s Juan Toribio . Glasnow’s changeup has never been a primary feature of his arsenal, topping at a 10.3% usage rate in 2017. It also hasn’t been a particularly effective pitch, save for in 2019 when hitters managed to slug just .125 against it, albeit in very limited usage (3.5%). It’s certainly intriguing to dream on a splitter to compliment Glasnow’s two lockdown offerings, but the pitch will have to survive spring training before taking on much (if any) significance. On a night of high drama, let’s check in on a couple other pitchers…

• Michael Wacha recognizes the starting depth he will be contending against in Mets camp this spring, but he’s undaunted, per Newsday’s Tim Healey. After all, as Healey points out, Wacha twice fought his way back into the Cardinals rotation last season after time in the bullpen. Of course, that might also be a sign that he’s the likeliest of the Mets’ six rotation candidates to start the year out of the money (both literally and figuratively, given the incentives in Wacha’s contract for games started). Wacha finished last season with a 4.76 ERA/5.61 FIP across 126 2/3 innings, and he’s only twice crossed the 150 inning threshold. It’ll be an uphill climb for Wacha to make the rotation by opening day, but it’s not impossible. Given the injury rate, there’s a decent chance he finds his way into the rotation at some point in 2020 regardless.
• Jack Flaherty isn’t eligible for arbitration until after the 2020 season, which means he can’t test free agency until following 2023, but the Cardinals ought to do their due diligence in locking him up now, writes Ben Frederickson of the St. Louis Post-Dispatch. Easier said than done of course, especially with a player who has already shown signs of understanding his tremendous value. Frederickson recounts Flaherty’s rejection of the Cardinals salary offer before last season, which cost him $10,000, though the penalty was worth it from Flaherty’s perspective. The statement he was able to make about the current system was of bigger importance to the Cardinals’ ace. That’s a good sign in terms of Flaherty’s character and competitive spirit, but perhaps less so for Cardinals fans hoping for news of an early extension. Flaherty’s displeasure with the arbitration system has little to do with the Cardinals, of course, but after a dominant 2019 in which he posted a 2.75 ERA/3.46 FIP, including a mind-boggling 0.91 ERA in the second half, it’s understandable for Flaherty to be at least a little displeased at making close to the league minimum.
