The 2014 U.S. Open is less than two weeks away. The Western & Southern Open in Cincinnati, the last of the major tune-ups, concludes this weekend.
Apparently, some players need more fine tuning than others.
So who's hot and who's not?
It depends on the barometer used to measure summer success. In this case, players are considered hot if they are playing above expectations, have looked impressive in recent matches or pulled off notable upsets.
Those considered not hot are playing below expectations, are on a losing streak or have suffered an embarrassing upset.
Serena Williams, who is having a Slam-less year so far, qualifies as neither because despite her off year, she has won more titles this season than anyone on the WTA Tour.
Meanwhile, Rafael Nadal hasn't played since Wimbledon. With his appearance at the U.S. Open questionable, Nadal is unofficially lukewarm.
