I know rburgh usually posts these, but I ran across this factoid and found it interesting

Who was the last 18 year old to hit a major league home run?

I'd guess Juan Soto

he hit one as a teen, but he was 19

Julio Urias

Robin yount

and there is the winner. He had 3 before he turned 19.

I remember that the player last to do it before Yount was Eddie Kranpool of a favorite of all Met fans
