Jack Sock got to have a little bit of fun in Delray Beach, where he was asked to judge a sock competition, judging past and present players on their sock choices.

First on the chopping block was Sock's Olympic gold medal-winning doubles partner Bethanie Mattek-Sands. In her American flag high socks, Sock ruled that her sock game was strong.

Next up was Mardy Fish, who tried hard to make "barely there" socks a trend. Without hesitation, the 24-year-old Sock ruled Fish's sock game weak. 

He then judged Anne White, who wore an all-white spandex outfit and aerobic socks at Wimbledon in 1985. Sock said the getup looks like something you'd wear to a "throwback disco party."

The world No. 21 also got to cast his thoughts on Serena Williams (twice), a very unusually dressed Nicolas Mahut, and Novak Djokovic's magic marker-designed socks for Japanese tsunami relief awareness. 

Sock laughed the most at Andy Roddick, who wore an all-white outfit with black ankle socks. Luckily, Roddick is a fellow Nebraskan, so Sock had to be nice to him.

The American certainly got some laughs out of the sock game ahead of a busy week in Delray Beach, where he's seeking his second title of 2017.
