17. Single-Season HR Record (73)
Set By: Barry Bonds
Say what you will about his personality and what he allegedly did to get this record, but Barry Bonds has never been convicted of anything. So, if you ask us, this record is just as legitimate as any other set in the steroid era of baseball. The combination of health, luck, and incredible physical strength and stamina required to hit this many home runs makes catching this record a near-impossibility. Then again, we don't want to count out the scientists hard at work right now trying to create the next home run-crushing monster. We're pretty sure Jose Canseco would offer himself up as a guinea pig.
