A visit by a Springfield Elementary alum-turned-Ivy-League student pushes Lisa to question her own go-getter attitude and reevaluate the scope of her extracurricular activities. Convinced that there is no such thing as having too many clubs or activities listed on her resume, Lisa jumps at the opportunity to coach Bart's little league team. Despite having little understanding of baseball, Lisa coaches the team to a record winning streak by putting her book smarts in statistics and probability into play. But when Bart questions Lisa's coaching tactics and confronts her for taking the fun out of baseball, Lisa benches him from the championship game. Hoping to lift his spirits, Marge spends the day with Bart at an amusement park where MLB manager and former catcher Mike Scioscia (guest-voicing as himself) gives Bart sound advice and reminds him of his genuine love of the sport. Meanwhile, with one last chance to win the game, Lisa makes an unexpected call and learns that there is more to sports than winning.
