If it was a hit and run, he wouldn't have been at third by the time the ball crossed the plate. It was a straight steal.
There's really no need to defend Desmond to the teeth. He can make a youthful mistake just like anyone else.
When the freak have I turned it into an excuse, I saw desmond take off and zim swing...who's to say it was/wasn't a straight steal or hit and run. To me it looked like hit and run to get something going.
