Aaron Hicks discovered something that a lot of hitters never seem to figure out (like Danny Santana): If you turn your butt towards the pitcher, raise your front leg, and hold the bat in the pads of your fingers (rather than the meat of your palms), then it's easier to deliver a powerful blow to the baseball. But even better, it's also EASIER to check your swing. Plus, the extra velocity you impart to the ball will drive more grounders through the infield and more fly balls over and around the outfielders. It may seem contradictory that preparing for a powerful swing makes you a better hitter. Aren't you committing your weight and motion earlier? Slightly. But you're also better reserving your finish, which is the part where your bat cruises with power through the hitting zone. The bigger coil allows you better to hit outwards to the ball, which in turn makes the barrel carry farther along the hitting line. That gets you fatter contact and a wider spray pattern. Better still, because the power is created so far back, you don't have to try to generate power late with your arms, which Hicks used to do. Instead, you just work on channeling that early power, the way he's doing now. Best part is, you can still push the Cancel button quickly on a butt swing, the way Bryce Harper does. You just don't let the barrel carry, instead yanking it back. This is actually easier for him, because the bat head doesn't start its propeller motion until late in the swing. It's butt/kick, shoulders, hands, bat head. If the pitch looks bad, you keep the bat head back. You should be able to tell how powerful a guy's swing is by how impressive his check swing is. Everything looks powerful except that last flip of the wrists. Hicks is now starting to get that. Fun to watch.
