You know how he does....gives off the "ima bout to pass out" routine and looking all dumbfounded at his box, etc etc. Then he throws the set and comes back the next set like nothing happened once he gets the lead back. Him and Rafa got that down to a science lol
I realize.
I know it can work on some juniors..they take the foot off the pedal to conserve for their next match thinking the opponent is done
But as a pro?! Idk man

when Fed most of his majors it was a weak period.
Thiem felt that pressure and stumbled and that's all Novak needed.
