Rafael Nadal and Andrey Rublev will face off Wednesday with a spot in the U.S. Open semifinals on the line.
Nadal is the top seed in the men's singles draw, and looks like the favorite to win the tournament. He beat Alexandr Dolgopolov 6-2, 6-4, 6-1 Monday to reach the quarterfinals. If Nadal wins, he could potentially play Roger Federer in the semifinals—a first-ever U.S. Open meeting between the two longtime rivals.
Rublev, only 19, was hardly expected to reach this stage of the U.S. Open. But the young Russian has shown he's ready for the big stage, beating both David Goffin and Grigor Dimitrov in straight sets on his way to the quarterfinals.
