Single voter who left James Harden off MVP ballot says it was a mistake

James Harden's name appeared in the top five of every Most Valuable Player ballot with the exception of one.  

The Houston Rockets shooting guard, who lost the award race to Golden State Warriors point guard Stephen Curry, was included on 129 of 130 ballots.  

The lone voter who disregarded Harden took to Twitter to explain that it was a mistake. 

It does seem as though it was unintentional. When Chris Haynes released his postseason ballot in April, he had Harden as No. 3, behind Curry and LeBron James. 

That's one big oops.
