    (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."
