Jack Sock shows good sportsmanship, tells opponent that his serve was in

Good sportsmanship is not dead as it turns out.

And all it took to come to that realization was to see this video of a tennis player, who attended Blue Valley North High School.

Sock was playing Lleyton Hewitt in the Hopman Cup in Perth, Australia, when Hewitt’s first serve was ruled out. Sock told Hewitt it would be a good idea to challenge the call, which certainly surprised Hewitt — and the umpire.

Hewitt was losing at the time, but rallied for a 7-5, 6-4 victory.
