No one has mentioned Micky Mantle, so I will. No one ever hit a longer ball and he did it with Four Roses Whiskey and Pabpst Blue Ribbon Beer.

Babe Ruth hit many more long homers than Mantle and everybody else. Read Bill Dickinson's "The Year Ruth Hit 104 Home Runs." Dickinson charted all the long shots (homers, other extra base hits, and outs) Ruth hit during the 1921 season where the Yankees played their home games at the Polo Grounds with the center field fence 490 feet away.

He also charted many of Ruth's other long clouts in other ball parks that season. Many pitchers refused to pitch Ruth anything but bad, usually far outside pitches. Ruth, if he didn't want to walk every time, was forced to swing at many "bad" pitches. Since the bad pitches were usually outside, Ruth hit many long shots to center and left center field. Some clouts were homers or extra base hits, but many were just incredibly long outs.

Dickinson also investigated long shots by other players including Mantle and concluded that their longest shots still didn't match the distances of Ruth's clouts. He claims nobody has yet hit baseballs as far as Ruth hit them. And yes, he investigated Mantle's famous shot off the facade at Yankee Stadium and concluded that it wouldn't have gone as far as many people claimed.

Dickinson's final conclusion was that if Ruth had played that season in a ball park with the dimensions of modern ball parks, he would have hit over 100 home runs.
