The eight Detroit winners were set to be recognized during a pregame ceremony before the Tigers face the White Sox on Saturday afternoon. If any of them place in the top three of their age group nationally -- regional competitions are taking place at all 30 Major League ballparks -- he or she will be invited to the national competition during All-Star Week on July 13 prior to the Home Run Derby in Cincinnati.
The finalists will be announced June 28 on MLB Network.
Kaitlyn certainly made a case for herself on Saturday. During the hitting portion of the competition, she launched three of the deepest fly balls of the morning from any group.
"Kaitlyn is always shooting for the stars," said her mother, Kathy.
The event marked Kaitlyn's sixth time competing at this level of Pitch, Hit & Run, according to her family.
"Being able to be on the field was fun, because not a lot of kids get to do that," Kaitlyn said. "I'm very happy that I can go out there."

"It was a big step for her to make it here," Kathy said.
