Alexandra, also known as Al, has been playing baseball with her older brothers for as long as she can remember. But when she ages out of Little League, it seems like it's the end of the road for Al and the sport she loves. Until, that is, her friend Sammy suggests that Al try out for the middle school team--a team that has always been boys-only.

Al is prepared to fight for her right to try out, but to her surprise, the coach is delighted by her interest. When Al makes the team, it seems like everything is going to work out. But with a tenth consecutive championship on the line for Brinkley Middle School and a team that can't seem to get along, will their season ground out faster than Al can say "home run"?
