Two rookie 1st Basemen on the same team came up the same year & became Hall of famers.
Hint one held the HR Record for two teams for many years. The other makes this a kind of trick question, both are well known.
The other guy had one major league AB. The slugger was the only guy ever to hit over 50HR without striking out 50 times. Also I'm pretty sure he was the only guy to ever lead the league in triples without a stolen base!
