Not a frequent selection of Lamet’s, the changeup yielded a low swinging-strike rate (29.4%) on just 17 individual uses in 2019.
Giving up a .404 WOBA and 160 wRC+, one would assume this is a pellet in Lamet’s arsenal — and with just a 13.2% K rate, one would be right.
At an average 96.1 mph velocity, Lamet pipes the four-seamer in there hot. The problem? Opponents devour it on sight. With a .428 WOBA and 173 wRC+ in 2019 (though on an unrealistically high .368 BABIP), the pitch yielded an ugly -8.2 pVAL.
The cherry of Lamet’s arsenal, the slider yielded a filthy 23.2% swinging-strike rate, a baritone-low .197 opponent WOBA and 25 wRC+, and a knee-buckling 51.7% K rate (yes, you read that correctly).
Lamet has a good fastball with above-average velocity (around 95 MPH on average) and some backspin on it. It generated a lot of fly balls in 2017 (43% of the time), which also resulted in a fair number of home runs, with a 19.1% HR/FB rate and .292 ISO against it.
Lamet’s slider comes in around 85 MPH and has above-average horizontal movement. It generates a good number of strikeouts, with a 42.1% strikeout rate in 2017 and an 18.2% whiff rate. And if the pitch wasn’t striking someone out, it resulted in a ground ball at a 48.5% rate.
Lamet’s change is thrown very hard, around 90 MPH on average, which can limit its effectiveness a bit, however the above-average movement makes it a pitch that’s easy for hitters to miss. In 2017, the pitch generated a 13.3% whiff rate, though Lamet had trouble controlling the pitch, throwing it in the zone just 43.4% of the time. Because of that, Lamet was prone to making mistakes with it, as opposing hitters had a .419 wOBA and .278 ISO against the pitch.
