This is not how you go about this type of data analysis
Look at extreme fly ball hitters over large sample sizes. The effect is clear. Joey Gallo being the obvious example. .260 career BABIP despite being fast and hitting the ball hard as f***.
These afflicted players can still have extremely good seasons, through variance.
Yeah Martinez' .216 BABIP might be partially bad luck but the story is the same this season whether he's hitting .199 or .235, really. Either way he looks like a guy with an approach and contact issues that MLB pitchers can PROBABLY exploit to the point of failure. Unless he makes a big change.
Also, completely different consideration with Volpe. His statistical context is not the same. You can say with Volpe that if he had a better trajectory on his batted balls he'd be a f***ing .300/.400/.500 hitter. I mean he has the K-BB and power skills to hit .300 and BABIP .320 in the minors, clearly. So yeah you've identified Volpe's problem; the reason he has a 122 wRC+ and not a 150.
