Sock looked to be ripe for a significant drubbing when he lost the opening set 6-1 to the big-serving Anderson.
However, he rallied impressively to force a decider as he claimed one of just two break opportunities ceded by the South African in the second set.
It was a similarly tight third set, but Sock did not give an inch on his own serve and earned the vital break to see out an impressive victory. Per tennis writer Chris Goldsmith, it was some turnaround from the world No. 26:

Ferrer's was a routine victory over Rosol, the Spaniard looking in fine form at one of his favourite events.
A double-break in the opener saw him off to a quick start, and the Czech never really looked like mounting a fightback.
It was a tighter second set, but Ferrer gave Rosol no opportunities on his own serve and claimed the single break he needed.
Tsonga was required to battle a little harder in a 102-minute tussle with sixth seed Fognini. The pair exchanged service games in the opener before the Frenchman pounced as the Italian looked to force a tiebreak to win the opening set 7-5.
The second set was bereft of any break-point chances for either player, but Tsonga showed his quality in the tiebreak to claim victory.
Bautista Agut was impressive in beating third seed Isner, with the Spaniard showing steel to respond when forced into a decider and serve out the set having claimed the key break.
