(I hate to have to go back and edit, but I realized I made one mistake, leaving free agency on, so I went back and started over. Pretty similar results, Ruth hit 9 more, but I feel better with Rogers Hornsby not switching teams via free agency.)
Babe Ruth's first season as a Yankee was a success, belting 59 home runs to set the new single season home run record. With his display of power Ruth moved up to 6th place on the all-time home run list with 108, and the leader among active players. Ruth is 30 home runs behind all-time home run king Roger Connor, who Ruth could pass during the 1921 season.
1920 is the year we begin tracking two new categories, most home runs by a rookie, which currently goes to another Yankee, Bob Meusel who slugged 16 homers. The Yankees led the league with 117 home runs, led by Ruth and Meusel.
