Federer and Djokovic rallied to win

Once, Roger Federer was a perfect closer of the match. For years, when he won the first two sets in a Grand Slam, he never lost. His flawless streak ended when he surrendered to Tsonga in the quarter-final of Wimbledon, and it happened again in the semi-final against Djokovic at the US Open. On Tuesday, Roger showed the part of this troubling trend and, at some extent, the aging process.

At two sets down, Fed Express rallied to win the last 3 sets for a spectacular comeback. How did this happen?

Federer and Potro both made 43 unforced errors, while Roger had 59 winners and Martin only managed 33. The total points score is 149 and 124. While Federer has 83% net approaches, Potro only has 57%. All other statistic showed that the 30 year old champion still posses the desire to once again crown another Grand Slam after two year not able to. At the end of Set 2, unlike his normal self, Roger screamed "Shut Up" at one of the audience, who unsportingly shouted when the game is in progress. Does he have what it takes to overcome Djokovic, the number 1, in the semi-final, we will see soon tonight (Check out the betting opportunities at 36BOL.com). Here is the complete stats for the troubling comeback from the former number 1:

Djokovic came off worst from the battle with French man Tsonga at set 3, and saved 4 match points at set 4, but able to close the match after 5 sets long and proceeded to semi. Tsonga later commented: "You want to break your racket. You want to shout. You want to cry. You want to laugh and say, Oh come on. That's a joke. How could I lose this match?"

It's true though, as the French player, supported by almost all the spectator in his home ground, was better in his shot, his skills. He just does not have the incredible mentality that Djokovic has which allowed him to save 4 match points at set 4, and finished the last set with huge gap. Let's take a look:

Some other interesting statistic:

- Top top six seeds reached the quarter finals, marking the third time in 44 years of the Open era that has happened. 

- Federer's recent success has paled only in comparison to his earlier, unprecedented self. The Swiss champion reached 22 of 27 Grand Slam finals while he won the record of 16 major titles. Then there was his wondrous run of 23 consecutive semis as well as his streak of 32 times into quarter final.
