Chase Burns gave up 7 runs in 1/3 IP tonight…. Chase holds his glove with the muscles of motor tract 5 so he has no choice but to tip his slider… He did it last time out vs the Yankees too but New York doesn’t seem to have this tell…. They missed it vs Severino yesterday

The “magic” of Shohei Ohtani’s swing…..A lateral prehension grip. The intrinsic muscles of his hands grip the bat, which allows the extrinsic muscles in his forearm to extend his wrists when he swings. The majority of the musculoskeletal movement in the swing is involuntary

Jesus Luzardo pitches vs the Red Sox tonight…. Luzardo has tipped his breaking ball from the stretch all season long…. There are a couple of guys in Red Sox uniforms that have feasted on this tell for the better part of a decade… Jesus has tried setting his hands at his

Roki Sasaki was tipping his pitches again last night… There are so many tells in his setup that it’s remarkable the Dodgers keep running him out there without fixing this… His entire right side moves differently when he throws a splitter. You can see it just by looking at

Jed Hoyer says that Kyle Tucker’s finger injury is the cause for the change in his mechanics…… That couldn’t be further from the truth…. Here’s Kyle hitting a double on June 13th vs Paul Skenes vs Kyle rolling a ground ball into RF for a single on Saturday…. The fix is so

Fernando Tatis hit .235 with 2 HR’s in June using the muscles of motor tract 5 on his right side…. He hit .282 with 40 HR’s in 2021 using the muscles of motor tract 1 on his right side… It wouldn’t take much for Fernando to get back to using motor tract 1 again….he’s done

Didier Fuentes gave up 8 runs in 1 inning of work last night…. Fuentes tips his breaking ball from the stretch and the A’s were all over him…. The A’s have several pitchers with this exact same tell so I’m sure they are more than familiar with what to look for…. Fixing this

Cam Schlittler is pitching vs the Blue Jays tonight…..The Blue Jays are the best team in baseball at picking up a pitcher tipping his pitches. Cam uses the muscles of motor tract 5 on his left side so he tips his breaking ball from the stretch…. The only way a pitcher can get

He changed how he holds the bat and that completely changed his swing. It’s hard to imagine Gunnar swung like that his whole high school career. He was probably in a funk and didn’t realize how his grip was affecting his swing.
