Last year I correctly predicted 3 of 4 women's quarterfinals and correctly predicted 3 of 4 men's quarterfinals. This year I also have made predictions for the women's quarterfinals. Below are my predictions for the men's quarterfinals at the 2013 US Open.
Novak Djokovic (SRB)  vs Mikhail Youzhny (RUS) . The World #1 has been devastating so far through the first four rounds, serving up three bagel sets (including two in his 4th round demolition of Marcello Granollers) and losing on 22 games and no sets. Youzhny is coming off one of the greatest comebacks in US Open history, having beaten 2001 US Open champion Lleyton Hewitt despite being down 1-4 in the 4th set and 2-5 in the 5th set, eventually winning the match 6-3 3-6 6-7(3) 6-4 7-5 in four hours of play to reach his 3rd US Open quarterfinal. Even though he'll have two days to recover and has won his two previous quarterfinal appearance (against Rafael Nadal in 2006 and Stanislas Wawrinka in 2010). Mad Professah's pick: Djokovic.
Andy Murray (GBR)  vs Stanislas Wawrinka (SUI) 
Richard Gasquet (FRA)  vs David Ferrer (ESP) . This should be the popcorn match of the four quarterfinal round. Both Ferrer and Gasquet had to get through stern tests to reach this point. Gasquet survived the serving barrage (39 aces!) of Milos Raonic in the 4th round, escaping with a win despite hitting fewer winners (45 to Raonic's 102) by playing well on the important points: 6-7(4) 7-6(4) 2-6 7-6(11) 7-5. Ferrer ground down the talented Janko Tipsarevich in four sets despite trying to choke away his win repeatedly. However the history between these two players indicates that Ferrer has Gasquet's number. The Spaniard has an 8-1 head-to-head record over the Frenchman and despite his prodigious talents Gasquet has only reached a major semifinal once in hs career and this is his second quarterfinal appearance despite reaching the 4th round 16 times before. Mad Professah's pick: Ferrer.
