Tyler Glasnow (and Pitching Coach Kyle Snyder) on Making Strides
As noted by FanGraphs author Jeff Sullivan earlier this month, Tyler Glasnow has become a different and better pitcher. Being traded from the Pittsburgh Pirates to the Tampa Bay Rays is playing a part in that, but there’s more to his step forward than a simple change of scenery. The 25-year-old right-hander had already begun evolving.
Glasnow added a slider to his repertoire this year, giving him a third pitch to go with his high-octane heater and a curveball that has always flashed plus. He’s also started to elevate more fastballs, allowing him to take advantage of his velocity and above-average spin rate. Perhaps most importantly, he’s been getting his mechanics in order. Inconsistency has long been a bugaboo, with Glasnow’s 6-foot-8 frame getting much of the blame whenever he’s gotten out of whack with his delivery.
He’s back to a starting role now. The Pirates put him in the bullpen this spring, and he remained there until Tampa Bay finally pulled the trigger on an anticipated Chris Archer deal, acquiring Glasnow along with Austin Meadows and Shane Baz. The Rays promptly placed the high-ceiling hurler in their rotation, where they hope he remains for years to come.
Glasnow talked about the strides he’s made, particularly in terms of his repertoire and delivery, prior to a recent game. Also weighing in on the right-hander’s continued development is Tampa Bay pitching coach Kyle Snyder.

Glasnow on his two breaking balls: “They’re different grips, and the intent is different. Early in the count, I’m more of a curveball guy, while the slider is more of a put-away pitch. I would say my slider is the better of the two, but it’s easier for me to throw my curveball for strikes. I grip my slider like a traditional slider. My curveball is a pitch I release with the seams a little more parallel to my fingers.

“The break is similar, they’re both 12-6, so I think it’s maybe hard for PITCHf/x, or whichever technology is being used, to [classify them]. In terms of usage, I’ve been throwing them pretty evenly. The curveball is a little slower and kind of just drops in the zone. The slider bites a little sharper. It comes in off a straighter plane, then breaks down.
