Juan Martin Del Potro defeats Roger Federer in the men's quarterfinals at the US Open 2017

What an insane quarterfinal match tonight between Juan Martin Del Potro and Roger Federer!! Del Po is on a roll! He pulled off an INCREDIBLE win against Dominic Thiem on Monday, and again an unbelievable feat over the un-touchable Roger Federer!!! The 3rd set tie break was a serious nail biter! Del Po overcame 4 set points to then go ahead and win the tie break! Del Po then took the match in the 4th. There were moments where it looked like perhaps a 5th set was on its way, but Del Po's brute power shut Roger down. Even with a clearly weakened backhand due to several injuries/surgeries on the left wrist, he still came out victorious over the domination sensation know as Roger Federer. Wow wow wow!!! What a match!!! Catch some great footage here, and of course, the winning point and end of this amazing match.
