Rodriguez is among only three players, along with Reggie Jackson and Darrell Evans, to hit 100 home runs for three different teams.
For one of the most scrutinized players in baseball, there was little fanfare in the run-up to No. 600 -- perhaps it's Steroid Era fatigue or the fact that Rodriguez became the fourth player to reach the mark in the last 10 years after none in 31 years.
The pursuit of the home run record gets lucrative now. As part of his $275 million, 10-year deal signed after opting out of his contract during the 2007 World Series, Rodriguez can earn up to $30 million more for six milestone homers.
If Rodriguez ties Mays, he will receive a $6 million bonus. He'd get $6 million more each time for matching Ruth, Aaron and Bonds and breaking the record.
