Speaking of steroid-aided baseball sluggers . . . 

The ball Alex Rodriguez hit for his 500th career home run in 2007 will be auctioned online beginning Jan. 20 by SCP Auctions.

The same company sold Barry Bonds' 756th career home run ball for $752,467.

Be careful out there, prospective buyers.

Mark McGwire's 70th home run ball from 1998 went for $3 million at auction.

Three years later, Bonds surpassed that figure for a new single-season record.
