Rusney Castillo forgets how many outs there are, and throws ball to fan in stands (VIDEO)

Rusney Castillo's heart was in the right place, but the Red Sox right fielder's brain seemed to be somewhere else when he made a grab in right field and tossed the souvenir ball to a fan in the stands Wednesday night.

Too bad it was only the second out and there was an Indians runner on base.

The brain-freeze occured in the seventh inning of Boston's 6-4 win over Cleveland when Jose Ramirez popped up a fly ball to Castillo. The Red Sox fielder reeled in the ball and then flicked it into the Fenway stands to some fans waiting with their gloves outstretched — which would've been a cool gesture if the inning had been over. 

Abraham Almonte tagged up at first and casually strolled over to third on what was officially ruled as a throwing error on Castillo.

But since Castillo willingly threw the ball away, was it really an error?

Jason Kipnis struck out in the next at-bat — so no damage was done.

But at least the ball has a nice little story behind it now.
