Sock gets to practice and compete alongside former No. 1 Kim Clijsters, and the honor isn't lost on him.
"She's obviously a legend of the game," he says. "Any wisdom, any knowledge, we can get from her slash having her on the bench cheering us on and playing with her hopefully in mixed a little bit would be super fun."
Sock and Clijsters made their mixed doubles debut on Wednesday against the San Diego Aviators, winning 5-2. Sock also won his singles set and doubles (with Neal Skupski), and then captured the supertiebreaker to get the 20-19 victory for New York.
