Despite using his changeup sparingly, the pitch still ended up with a -4.1 pVAL. I’m sure a .685 wOBA did not bode well for the pitch.

Gray gave up too many long balls in 2018 with his curve due to lack of command so he curbed its usage by nearly 5% and saw better results. It is a solid enough off-speed offering but doesn’t seeve him well in Colorado, not with a 46.2% FB ratio anyway.

Per Pitch Info, Gray’s fastball was valued at -9.5, or the sixth worst fastball among pitchers who threw at least 150 innings. The pitch allowed a .403 wOBA and allowed more walks than it got strikeouts.

Gray made up for his poor fastball with an elite slider, which ranked as the 10th best slider. The slider was a “Money Pitch” and had an incredible 33.0% K-BB%.

Gray’s fastball has never been dominant, but it took a step further back last season posting a -15 pVal. He lost about three inches of horizontal movement, and hitters clobbered it with a .216 ISO. Unless he regains movement this pitch will continue to be ineffective.

While Gray’s slider posted a 7.8 pVal and was a great strikeout pitch, it ran into home run problems last season. His ISO more than doubled from .076 to .164. It did post a great swinging-strike rate and outside swing rate, so if he can limit the home run issue it will be very effective again this season.

Gray also mixes in a curveball with good success, holding hitters to a .194 BAA. It posted a nice 18.1% swinging-strike rate, but like his other pitches last season, needs to correct the long ball issue. Otherwise, is was a fine pitch with decent movement.

The changeup gets thrown less than 2% of the time, and for good reason. It has allowed a .310 BAA in his career, and hitters weren’t fooled with a 14.3% outside swing rate. With how little it is thrown, it is a non-factor in his arsenal.
