ROGER  FEDERER                    v         FERNANDO GONZALEZ        

3-6 7-6 7-5

World number one Roger Federer suffered a shock 3-6 7-6 7-5 defeat by Chile's Fernando Gonzalez in his opening match at Tennis Masters Cup on Monday.
The Swiss, who had never previously been beaten in round-robin play at the season-ending championships, is chasing his fourth Masters Cup title

Gonzalez had lost all 10 of his previous matches against Federer but he found some blistering form in the second-set tiebreak to level the match.

"I thought it was ridiculous some of the shots he was coming up with," said a shell-shocked Federer.
"I can't do much when he drills that incredible forehand in the corner. I wish I had an excuse but I just lost the tiebreak in a bad way and never got the edge in the third set."

Gonzalez has a ton of firepower and used his backhand aggressively instead of slicing it back.  Rarely is Federer out-matched, but on this day, Gonzo was superior.
