In Major League Baseball, the career record is 762, held by Barry Bonds, who broke Hank Aaron's record on August 7, 2007, when he hit his 756th home run at AT&T Park off pitcher Mike Bacsik. Only eight other major league players have hit as many as 600: Hank Aaron (755), Babe Ruth (714), Alex Rodriguez (696), Willie Mays (660), Albert Pujols (633), Ken Griffey, Jr. (630), Jim Thome (612), and Sammy Sosa (609). The single season title: Home run text: record is 73, set by Barry Bonds in 2001. Other notable single season records were achieved by Babe Ruth who hit 60 in 1927, Roger Maris, with 61 home runs in 1961, and Mark McGwire, who hit 70 in 1998. Negro League slugger Josh Gibson's Baseball Hall of Fame plaque says he hit "almost 800" home runs in his career. The "Guinness Book of World Records" lists Gibson's lifetime home run total at 800.

On September 23, Bautista became the 26th player in Major League Baseball history to reach the 50 home run club in one season, and the first Toronto Blue Jay player to do so. His 52nd home run set a new MLB record for the largest single-season increase in home runs, eclipsing Davey Johnson's 38 home run increase from 1972 to 1973. Bautista finished the 2010 season with an MLB-leading 54 home runs, the highest total since Alex Rodriguez hit 54 in 2007. title: Asterisk text: was called "61*" (pronounced "sixty-one asterisk") in reference to the controversy. The controversy over season length in relation to home run records had somewhat subsided by the time Hank Aaron broke Ruth's career home run record in 1974 (although Aaron received an even larger volume of hate mail and death threats which in his case often focused on race). Maris's single season mark was broken in 1998 by Mark McGwire and Sammy Sosa, who both broke it in under 154 games.
