The field for Saturday\'s singles semifinals in 16s has been set and one of the 18s spots is filled as the bottom halves of the draw battled through their quarterfinals matches today.

In 18s, Ryan Thacher (8) of Studio City , Calif., defeated Chase Buchanan (2) of New Albany, Ohio, 6-4, 7-5 and will play either Adam El Mihdawy (3) of Long Island City, N.Y. , or Ty Trombetta (6) of Hallandale, Fla., on Saturday.

In 16s, Evan King (2) of Chicago will play Denis Kudla (6) of Arlington, Va., in Saturday’s semifinals.
King beat Ben Guthrie (2) of Plano, Texas, 6-1, 6-0, while Kudla defeated Jack Sock (3) of Lincoln, Neb., 6-3, 3-6, 6-4.

“It still wasn’t easy,” King said of the rout. “He fought pretty hard and at the end he has some game points. At the end, he hit some good shots.
"I played really well. I didn’t really make that many errors, so it was a good day."

Kudla, who won on his fourth match point, said, "My serve still isn’t a thing that I’m depending on so much (but breaking Sock’s first serve) definitely gave me a little boost."

In the other half of the 18s semifinals draw, Ryan Harrison (1) of New Braunfels, Texas, will face Austin Krajicek (5) of Bryan, Texas.

In 16s, Ben van Overbeek (5) of Boca Raton, Fla., will play Jordan Cox (7) of Duluth, Ga.
