The 3 best known teenager success stories of all time.
Mel Ott hit 18 HR's at the age of 19 I think thats the record for teenagers, & hit his first at the age of 18
Jimmy Foxx came up at 17 & got 6 hits in 9 AB, .667, a harbinger of things to come, his first HR's came at 19
Phil Cavaretta at 18 played the most important roll of all hitting 8HR's starting at first for the Cubs helping them to the World Series
All 3 had long careers 2 became Hall of Famers.
