It's not the home run record that many predicted he would break, but New York Yankees third baseman Alex Rodriguez hit his 23rd career grand slam home run on Thursday night, tying former Yankees great Lou Gehrig's major league record.
A-Rod's eighth-inning blast came on a full count off Atlanta Brave lefty reliever Jonny Venters, who entered the game just two batters earlier.
The homer was the 639th of Rodriguez's career, leaving him 123 behind Barry Bonds' career record of 762. Manny Ramirez (21) is the only other player to have more than 20 career grand slams. Carlos Lee is the next highest active major leaguer, with 16.
