You wouldn't think you'd need to possess the financial acumen of a Warren Buffett to reach the conclusion that selling Barry Bonds' 756th home run ball was a wise investment.

But according to Matt Murphy, the decision to put the ball up for auction (where it is expected to net the New Yorker somewhere in the neighborhood of $500,000) was a lot harder than you might think. 

"I'm upset by the decision I had to make." Murphy said. "I wanted to keep it."

In his defense, Murphy also said the decision wasn't really all that hard and it came down to "simple math."

We're guessing part of the quadratic equation Murphy used to come to the realization that $500,000 > 0 involved the figure generated by the Mets fan's attempt to sell the Jose Reyes jersey he was wearing at the time he corralled Bonds' historic homer on eBay, complete with ketchup stains straight from AT&T park and signed by the home run catcher himself.

That would be a zero. Hey Matt, don't forget to carry the none.

But don't feel bad, Matt. A Jose Reyes jersey actually signed by, you know, Jose Reyes wasn't exactly raking in the dough either.
