My son is one of the streakiest hitters I have ever witnessed. There are times when he just doesn't miss the ball. During those streaks, he drives it all over the field or puts up long ABs, during which he spoils tough pitch after tough pitch, ending often in a walk or a hit. He once had a string of 26 PA's in which he was on base 22 of 26 times. He's had many multi-game hitting streaks. Longest, It think, was 18 games during an awesome summer ball stretch -- though he was on the young side then.
On the flip side, he sometimes goes into long stretches were he can't touch the ball -- At ALL. Once struck out 10 consecutive times in a tournament. He pulled the hat trick just this weekend -- though in fairness to him, one of his AB's was a quality AB in which he fouled off pitch after pitch and then was called out looking on a pitch 2 inches off the plate.
I can usually tell from his first AB in a game whether it's going to be one of those can't miss the ball games or one of those can't touch the ball games.
His college coaches have taken note of his streakiness and want to see him become more consistent. My question, though, is how do you do that?
