Glasnow’s curveball was brilliant in 2019, earning a 57.7% strikeout rate without ceding a free pass, and stymying opposing batters to a .167 BAA and .154 wOBA. Baseball Savant includes Glasnow’s go-to offspeed pitch in the 95th percentile in terms of curveball spin rate; top-shelf stuff for the live-wire Rays starter.

Glasnow’s four-seamer made big strides in 2018, including a 2.2-mph bump in average velocity to a studly 96.8 mph while topping out at over 100 mph. It also saw increases in swinging-strike rate to 9.3% and flip-flopped its ground-ball rate (46.5% in 2018) and fly-ball rate (28.0 FB%). This resulted in his fastball making the leap from a -8.1 pVal in 2017 to 3.6 pVal in 2018.

Gaining 3.3 mph in average velocity, Glasnow’s big, looping curveball was effective in 2018 with an 18.4 SwStr% and an insane 45.7 K-BB%. It limited hitters to a .167 BAA with a .152 ISO and a 51 wRC+. Its one bugaboo is in its tendency to give up the long ball—as evidenced by its 38.5 HR/FB%.

Though he threw is just 21 times in 2018, there are signs that this pitch could be the one that puts Glasnow over the top. Of the eight batters he used it against, five of them struck out. With nearly 15 inches more than the average vertical drop, the pitch put up an astonishing 28.6% swinging-strike rate and didn’t walk a single batter. It’ll be exciting to see if Glasnow lets this pitch loose in 2019 so we can really get a look at what it is capable of.

Glasnow threw his changeup just 32 times in 2018, and it didn’t get great results as it was shellacked to the tune of a .429 BAA and 117 wRC+. It did have a 71.4% ground-ball rate, but given that, Glasnow threw it 151 times in 2017. So the fact that he only threw it 32 times in 2018 could be signaling that he might be phasing it out.
