A little background. My DD is a small lefty playing her second season of 8U travel. Her former coach has ruined her swing. To take advantage of her speed he wanted her to hit pretty much everything to the left side. At first it was ok because she took good solid swings at outside pitches and drove the ball the opposite way with enough power to clear the outfielders and if it was on the ground she would generally beat out the throw.
After a couple of tourneys she was trying too hard to push the ball the other way and would try to hit every pitch that way. The ball could be on the inside corner and she would try and block it left. This has resulted in her straightening her arms way to early, almost the instant her swing starts. She hits to the left but there is no pop as she is basically dragging her extended arms through the zone.
Any suggestions on drills to help keep her hands in before extending to the ball at contact? Her current coach wants to worry about hitting the other way when she starts learning to slap this summer before we move into 10U.
