Lambert’s changeup showed up about 22% of the time in 2019 and flashed potential with a 40.1% chase rate and a 15.3% SwStr rate. Location was inconsistent with a 36.2% zone rate though, and with four home runs and a .950 OPS allowed, the results didn’t follow. With above-average drop and decent arm-side run, there is potential here, though with the current modest 7.4 mph velocity separation from his mediocre fastball, immediate progress might be limited.
Splitting time almost evenly with his slider, Lambert’s curve was used about 13% of the time in 2019, and had significantly weaker results than its breaking counterpart, generating weak chase (24.6%) and whiff (3.5%) rates, pounded to a 1.059 OPS against. While not a prototype 12-to-6 curve, it demonstrates more vertical tendency with above-average drop but still some slight glove-side action. It is in the zone 45% of the time, perhaps more than it should be given his current results.
Lambert used his primary four-seamer 53% of the time in 2019. Velocity (92.7 mph) and movement are both near or below average, and with a similarly below-average SwStr rate of 3.6%, results were less than ideal for Lambert in 2019; hitters ended up with a .957 OPS and a 28:21 K/BB ratio.
The least-used pitch (12.3%) in Lambert’s repertoire, the slider was nonetheless the better of his breaking pitches, even if results were still mostly average (28.5% O-Swing, 10.5% SwStr%, .804 OPS). The break on it is decent if unspectacular, showing more depth than run and used mostly to try to induce chases (35.3 zone rate).
