Jack Sock’s sportsmanship stuns Lleyton Hewitt

The look on Hewitt’s face says it all.

Hewitt was serving at 0-30 and 4-5 in the second set when his first serve was called out. Sock knew otherwise though and incredibly told his opponent to challenge the call.

A pretty flummoxed-looking Hewitt took a minute to compose himself before duly challenging the call.

The crowd ironically chanted “in, in” as the players waited for the inevitable – although, as the commentator duly notes, Sock would have looked “like a goose” if it was out.

The Australian went on to win the match 7-5 6-4.
