Shots of the real AAGPBL old-timers playing baseball.
As the real-life players' scenes play out, the final lines are given to an umpire whose call of "strike" is questioned. He retorts, "This is *my* opinion! Yesterday that might have been a ball, tomorrow that might be a ball, but today it's a strike."
This film is dedicated to the members of the A.A.G.P.B.L.
The cast is listed as a "Roster" with the Rockford Peaches listed by their positions.
