Summer baseball often puts a hitter on his own. Most instruction and improvement come from within.
"You become your own best coach," Wichita State outfielder Couper Cornblum said. "When you come back here, you're able to feel more relaxed in the box and make quicker adjustments."
The lead teaching tool is the wood bat. Wood bats expose holes in swings and bad timing, forcing hitters to hit the ball solidly to earn a reward.
"You get a lot of quick feedback with a wood bat," Cornblum said. "If you get jammed, you're going to know you got jammed and you're doing something wrong with your swing and your bat is lagging.
