Aaron Judge, a power hitter for the Yankees, and Albert Pujols, a legend for the Cardinals, are both trying to hit historic home run milestones.
You can watch their at-bats live on MLB.com and MLB Network,
starting with Judge, who hit his 60th home run in New York on Tuesday night.
Judge now has one home run fewer than Roger Maris, who set the AL record for home runs in 1961.
Only Barry Bonds (2001), Mark McGwire (1999, 1998), Sammy Sosa (2001, 1999, 1998),
Roger Maris (1961), Babe Ruth (1927), and now Aaron Judge, have hit at least 60 home runs in a season.
He already has 698 home runs, and once he hits number 699, fans will be able to watch his at-bats live.
