On September 14, 1987, the Jays set the record for most homeruns in a game, crushing the Orioles 18-3. The homeruns hit were by Ernie Whitt (3), George Bell (2), Rance Mulliniks (2), Rob Ducey, Lloyd Moseby, and McGriff. The record stands by a single homerun over the 1999 Cincinnati Reds.  This record is remarkable because the steroid era has come and gone and the record still stands.
