Taking on his opening-round opponent Marcus Copil in Washington, D.C., Jack Sock was loose. He was so loose in fact, he pulled out an insane no-looking backhand underhand shot, but lost the point.

No matter, as the American would win, 7-6 (2), 7-6 (5). Next for Sock is a third-round all-American clash with Jared Donaldson on Thursday.
