Often time young hitters struggle with turning and releasing their hips during game situations or live batting practice. This can be quite frustrating for coaches, especially for those who see their young athletes demonstrate a solid understanding of hip rotation during tee work, soft toss, short toss, or simple dry swings. There are usually two causes for lack of hip rotation in game situations.
Initiating the swing too late
When hitters start their swing too late, all they can do is defensively throw the bat at the ball. Late swingers do not have the time to take an aggressive pass at the baseball. As a result, they immediately go into survival mode.
You may have seen this even at the major league level, when a hitter with two strikes is thinking curve, but gets thrown a fastball. All that hitter can do is throw the bat late at the ball—all arms and no rotation.
Eliminating the stride and simply having hitters pick the front foot up and drop it down in the same spot (no lateral movement) will help hitters start the swing earlier. The key is mirroring the pitcher. When the pitcher’s front foot lands, the hitter’s front foot should land as well.
Fear of striking out and/or just being content with making contact
Hitters who have a fear of striking out become passive at the plate. They are content with just making contact, and not using their lower bodies in the process.
Especially at a young age, coaches should reinforce the idea that they would rather see an aggressive swing and a miss rather than a passive swing and poor contact. After a live round of a batting practice, hitters should be dripping with sweat. This aggressive mindset will help young hitters translate what they already know about hip rotation into game situations.
Many youth coaches use the phrase "squish the bug" as a means of giving kids a visual of what hip rotation looks and feels like. “Squish the bug”—the turning of the back foot as a means of initiating hip rotation—is not something I am hugely in favor of. If you want to turn your hip, turn your hip, and then the foot will follow. Big muscles pull small muscles, not the other way around. In other words, it’s not that turning the back foot is wrong, but ideally this should be an effect of hip rotation, not the cause. It’s important to understand that a player can still turn their back foot yet not achieve full hip rotation.
