Frank Robinson belts two successive grand slams during a 12 – 2 Oriole romp over the Senators
1970 – Frank Robinson belts two successive grand slams during a 12 – 2 Oriole romp over the Senators, just the 7th major leaguer to ever accomplish the feat. Dave McNally, the winning pitcher, Don Buford and Paul Blair trot home ahead of him on each blow. They will be Robby’s only grand slams for the O’s.
