    • Roger Federer and Nadal have never faced each other at the US Open

    (CNN)In their long and storied careers, Roger Federer and Rafael Nadal have never played against each other in the US Open.

    And it won't happen this year, either.
      Juan Martin del Potro, who stunned Federer in five sets in the 2009 US Open final for his only major title, took the rematch as well, winning 7-5, 3-6, 7-6(8), 6-4 Wednesday night at Arthur Ashe Stadium in Flushing, New York.
        Del Potro, seeded 24th, reaches his first major semifinal since 2013 at Wimbledon. He will face No. 1 Nadal -- who keeps the top spot with Federer's loss -- next, while the other semifinal pits No. 12 seed Pablo Carreno Busta of Spain against No. 28 Kevin Anderson of South Africa.
        "I think I played my best match of the tournament," del Potro said in his on-court interview. "I did everything well. I served so good. I hit my forehand as hard as I can. I think we played a great match, and I deserved to win in the end."

        It's the second time the Argentine, now 28, prevented a Nadal-Federer clash in New York. In 2009, del Potro defeated Nadal in straight sets in the semifinal en route to facing Federer in the final.
          "Hopefully I can repeat the result," del Potro said of his upcoming rematch with the 31-year-old Spaniard.

          Nadal did his part on Wednesday, dispatching 19-year-old Russian Andrey Rublev 6-1, 6-2, 6-2 in the afternoon quarterfinal. Prior to the start of del Potro's match, Nadal was asked about the possibility of playing him.
          "Juan Martin is a top player, no?" Nadal said. "It's true that when he's playing well, it's difficult to stop him. Probably the forehand is maybe the fastest on the tour. And of course to win tonight, he should be serving well. If he serves well and hit well his forehand, he's a player that have the chance to win against, of course, everybody.
          "If I play against him, of course I have to play my best tennis. I need to be very focused with my serve and play aggressive, because if you let him play from good positions with his forehand, you are dead, because he plays super-aggressive, hitting so hard."
          To get to Nadal, No. 3 Federer, 36, had to get through del Potro first -- no easy task for the Swiss. The Argentine entered Wednesday 5-16 against Federer, but all of those wins were on hard courts, including coming back from a set and a break down to deny Federer a sixth consecutive US Open title in 2009.
