***In this series we strive to prove the universal truth that every baseball player holds some kind of record.***
Appropriately this relic card is labeled "Double Header" and Robin's record deals with the same thing. Mr. Ventura is the only player to hit a grand slam in both halves of a double header.
This next stat isn't a record, but I think it's pretty amazing that over 6% of Robin's homers were grand slams.
