Tommy John
John had a respectable career when he joined the major leagues at the age of 20. After pitching for the Cleveland Indians and Chicago White Sox, the sinkerball pitcher was traded to the Los Angeles Dodgers and then the New York Yankees where he posted 20-win seasons. When Mark McGwire, whose father was John’s dentist, got two hits off of him in 1986 he said, “When your dentist’s kid starts hitting you, it’s time to retire!” He proceeded to play three more seasons.
