Half of baseball fans are rooting against Barry Bonds in his bid to break Hank Aaron's career home run record. That said, it's getting tough to find anyone rooting for the sport at all these days.

An AP-AOL Sports poll released Thursday shows that only one-third of Americans call themselves fans of professional baseball — about the level of support for the last decade, but lower than 1990.

And they see another problem competing with steroids: stratospheric salaries.

The poll also showed 48 percent of fans want the San Francisco star to fall short of Aaron's mark; 33 percent would like Bonds to break it and another 16 percent said they didn't care.
