I just played in an amateur tourney where I was sick and an in pain and I knew I was going to lose yet I completed the match. That's sportmanship.
He is a mllionaire ATP pro. The audience pays his salary. They want to see a completed match. They deserve to get what they paid for. I will never buy a ticket to tennis match to see a "quitter" play. He strikes me as an overpaid self-centered, twerp who doesn't know how lucky he is. Go ahead and quit the match, you stinkin' loser, but dont be surprised if your endorsement money dwindles or people don't go to your fake matches. (rest of my rant is self-censored).
