Sixty-one home runs used to be one of the most important benchmarks for MLB sluggers until 1998, when McGwire and Sammy Sosa both broke Roger Maris' single-season home run record. McGwire finished the 1998 season with 70 home runs, while Sosa was just behind with 66.
Then, Barry Bonds smashed 73 homers in 2001 to set the current gold standard for a single season.
After Thursday, Judge is already up to five home runs through New York's first 17 games. Washington Nationals star Bryce Harper leads the majors with eight, while the trio of Jed Lowrie, Joey Gallo and Mike Trout are pacing the American League with six.
Mounting a serious challenge to Bonds' record is probably out of the question for Judge, but he may be able to improve upon the 52 homers that helped him win AL Rookie of the Year in 2017.
