At a -2.5 pVAL with high contact numbers (for a changeup), an opponent wOBA of .327 and wRC+ of 111, the changeup was Webb’s least effective pitch in 2019. A K rate of just 17.0% suggests changes are necessary for the pitch to become any kind of weapon.
Webb captured some wonderful pVAL (6.5) and fly-ball rates (27.5%) on a pitch which had previously given him trouble, despite registering a comparatively weak 90.1 average velocity. The pitch yielded just a .184 BABIP, however, so a correction seems likely moving forward.
Webb stepped back from the slider in 2019, despite the pitch registering a solid 5.0 pVAL, 11.8% swinging-strike rate, and yielding a staggeringly low .059 WOBA. In fact, the pitch was hit just once in 127 throws on the year, suggesting that Webb would do well to reintegrate it into his arsenal.
Webb features his fastball more than half the time. The offering has below-average velocity but generates a good amount of swings outside the zone and a solid 12.3% swinging-strike rate. In addition to getting swings and misses, Webb utilizes the pitch up in the zone get pop-ups and weak contact.
Webb’s main secondary offering is his slow slider, clocking in around 79 mph. The looping slider is not the standard chase pitch, as its chase and swinging-strike rates are well below-average. The slider does generate a ton of weak contact and produced just a 36 wRC+ in 2018. Webb is around the zone over 50% of time with the slider, so it’s effective at both called strikes and weak contact.
Despite an 11-mph difference between the changeup and the four-seam, Webb was not successful with the changeup. In a limited sample, batters hit .417 against it and were able get it in the air quite often. Webb likely needs more vertical drop from his changeup to be successful.
