In an ESPN profile of Bunbury, it was learned that she never played baseball as a kid. Instead, she picked up soccer, track and basketball.

Bunbury is frequently asked if the show is about Mo'Ne Davis, a 15-year-old girl who pitched during the 2014 Little League World Series. Although the story is similar, the producers say no.
Because of Major League Baseball's cooperation with the show, Ginny Baker (played by Kylie Bunbury) dons an official Padres uniform and actually toes the rubber in Petco Park.
Kylie Bunbury (Ginny Baker) throws a mean screwball in real life.
