I'm pissed at Wawrinka because he's performance was not only a disservice to the spectators, it was also a disservice to Rafa. By "tanking", Stan effectively denied Rafa thw opportunity to play to his current best - whatever that may be. In so doing, he denied Rafa and tennis fans the opportunity to gauge Rafa's current level. In so doing, he may have denied Rafa the opportunity to win his next match, because Rafa wouldn't be able to identify areas of his game he might need to tighten up before his next match. In so doing, Stan went against the spirit of sport. His performance was also unbecoming of a French Open champion. It was also unbecoming of the world number 4.
