5 HR and 15 RBI in a game

In the best single game peformance by a player I've ever had, A-Rod had 5 HR and 15 RBI in one game in the 2000's Mystery Card set. Two grand slams, two three-run homeruns and a solo homerun.

Wow

I guess you've got one of ARod's juicing cards then?

Both would be major league records. Jim Bottomley had 12 rbi's in 1924. 18 players have hit four homers in a game. You might have to change your name to Juiced AR
