Seadevil's recently lost game...

Seadevil recently lost a game. However, I don't see why he resigned. He was up 2 pawns and he looked fine position-wise to me. I'm not very good at analyzing games so can somebody please explain this to me?

Thanks for the link irontigran. Also, thank you to Mac and Sicilian for your explanations. I had no idea any of that could have happened. Thanks again guys.
