Although he's certainly no actor, it's still worth noting that John W. McGraw, manager of the New York Giants in 1917, played himself in this light baseball comedy. William Vandervoor Cosgrove (John Drew Bennett) is Yale's star ball player. Sam Heegan, a scout for the Giants (Edwards Lawrence) brings manager McGraw news of Cosgrove's talent. Cosgrove, meanwhile, is busy getting involved with a vaudeville star, Madame de Montignon (Viola Cain). When he discovers that she is actually Leonora O'Brien, the daughter of a Chicago plumber, it makes no difference to him. However, his father, a wealthy pork packer (George Henry), is horrified and he and Mrs. Cosgrove (Helen Strickland) threaten to disown him. When this doesn't move their son, they try to buy off Leonora, all to no avail. McGraw signs Cosgrove up to the Giants, and after he hits the home run that wins the World Series, his parents welcome him -- and Leonora -- back into the family.
