"I'm very excited," said Witt, 13. "I'm ready for the challenge."
Sunday's regional competition took place at the Astros Urban Youth Academy. In the second of two rounds, Witt bested the other three competitors by homering on 10 of the 20 pitches from the ATEC M1 Pitching Machine to secure his place in San Diego.
"I was expecting to win it," said the right-handed-hitting Witt, whose father Kevin played parts of five seasons in the Major Leagues. "I loved the challenge. It pushes me."
In the final round, Witt hit first in the order and put up the high number that proved to be enough.
"I was nervous at first," Witt said. "But once I got a few swings, a few home runs, then I started to relax and calm down and get the hang of it."
While Witt dominated the 14-and-younger competition, in the 12-and-younger final round, the right-handed-hitting Bolcerek was a surprise winner over Beau Edwards, who hit seven home runs in the first round, five more homers than anyone else in the round.
The scores were reset for the final, where Bolcerek hit five home runs to Edwards' four homers.
"This is unexpected," Bolcerek, 12, said. "I was just going to try my hardest and hope to win it. I was nervous. but I was relaxed."
Bolcerek batted second in the final round order and Edwards batted third. Bolcerek put up a number that held up.
"The ball was inside on me and I was getting jammed," Bolcerek said. "So I backed out and I was able to make better contact with the ball."
In the 12-and-younger competition, the fence distances ranged from 180-225 feet. The distances ranged from 200-250 feet in 14-and-younger.
