We open serve with tennis and action from the Australian Open. Sweltering heat has been called brutal by some players, but it has not seemed to bother defending champion Roger Federer. Feds has not dropped a set in his opening two matches, and was lucky enough to play in the evening in Melbourne in his third match against Jan-Lennard Struff -- when play began temperatures dipped from highs of 42-Celsius to something about ten degrees cooler.

The Artful Roger would have the right Struff in the opening set, getting this ace to seal the frame 6-4. The German was Hanging Tough in the second, but the Swiss is too good, firing a backhand winner en route to taking the set 6-4.

And step by step, the 19-time grand slam winner prevails, despite being pushed to a tiebreak in the third. The defending champ is through in straight ones in less than two hours, after the match Feds discussed the heat that has affected the tournament.
