I have to admit I’ve only seen him a handful of times, had to go back and compare some notes to make sure info was up to date. Joey is a really interesting pitcher for sure. P2F summarized it up pretty well, I’ll just reiterate a few things.
Joey Murray has been known to throw an “invisi-ball”, it’s a high spin rate (2400+ rpm) fastball with good movement paired with a deceptive delivery. The spin rate makes it just a tad harder for hitters to pick the laces and identify the pitch, but also it rises/elevates on occassion which generates whiffs. Hence it seems “invisible”. This is especially effective because Joey works extremely fast (Mark Buehrle-esque) and comes after hitters repeatedly.
He also has an unique delivery, ultra-high leg lift (like Thornton) but an extreme forward stride while releasing the ball last moment. I think he even deliberately hides the ball behind him. It adds to the deception when paired with how fast he works and the spin rate, while also shortening the distance from mound to plate. He also throws from a high slot. It’s a bit difficult to explain. It’s worked well for him since college, and he has always been a high K rate guy.
He’s a decent size at 6-2 but doesn’t throw high velo. His fastball generally sits 86-89 and touches 91. I have to emphasize he throws a lot of fastballs. But you’d be surprised he sits on a lot of 86-87s but the FB definitely plays up because of all the quirks in his delivery, I’m guessing the hitters feel the same pressure as a 92-93mph FB despite being high-80s.
Pitchers with lower velo tend to have less margin for error, when you miss spots it basically becomes a BP fastball. Guys that can’t get away with elite type stuff generally have to learn how to pitch, by mixing pitches very well, studying hitters, and have plus polish in their command to remain effective.
I hear his changeup has been much improved and has good velo separation, he’s polished it a lot in Lansing and commands it for strikes. The slider has good horizonal break and almost acts like a low-velo cutter. And he has a high rpm curveball which sits mid 70s. His goto secondary back in College and Vancouver was his slider, but now it’s more of a mix including the changeup and curve. If I had to loosely grade his pitches, his FB probably a 50 (45 velo, 60 command/movement), 55-60 slider, 55 curveball, 50 CU. (Might be a tad generous)
The change of speeds, the quirky delivery, the FB spin rates, and multiple secondaries make him a very effective strikeout guy despite the low FB velo. It’s just too bad he’s right handed, scouts would probably be higher on him if he’s a southpaw.
I wouldn’t exactly say Gaviglio, he’s more of a right-handed Buehrle. I honestly have no idea if his stuff will work in the MLB as a starter, probably why he dropped to 8th Rnd despite being very effective in college. He’s always induced a lot of K’s and never had much walk issues, which could mean BP as a plan B, maybe a long relief role. The improved CU also bodes well for his chances.
We’ll see what happens in double-A.
