Rangers hitting coach Rudy Jaramillo (center), who helped send Kapler (right) on a 28-game streak, hopes to work his magic on the struggling Ledee (left). Here's what the guru of Texas swing looks for when watching a batter at the plate.
1. RHYTHM: A hitter has to establish a preswing rhythm that leaves him set in time to pick up the pitcher's release point. That means staying balanced and keeping the hands and arms tension-free.
2. SEPARATION: "I'm always watching the hitter's feet," says Jaramillo. "If they're not separating properly, that rhythm is going to break up." When the batter's front foot lands, his hands should be cocked in a power position.
3. STAYING SQUARE: When the hands are cocked, the hitter's shoulders should be square with the plate. That helps keep him from lunging at the ball and keeps the upper body from flying open or from turning inward and limiting the swing.
4. WEIGHT TRANSFER: "We work from the legs up—the foundation of the swing is the transfer of weight from the back to the front foot," says Jaramillo. A smooth transfer creates bat speed, the Holy Grail for hitters.
