He got through 2 rounds of qualifying plus 3 main draw matches. Has been on the tour for yonks. Has made a good pay check out of this tournament. Had absolutely nothing to lose. Expected to lose I imagine. So just went out to give it all he'd got. Not surprising he was quite tough to beat.
Note this was in response to your second comment. I have been awake far too long...!!! Did you manage to actually watch the match?
