Andy Murray showed that he is a vastly improved clay-court player this spring by reeling off a 16-match winning streak and nearly upsetting Novak Djokovic at Roland Garros. But the Scot still has a bit of work to do on the basketball court. Murray went 0 for 5 in the NBA half court challenge, but he did come very close on a few shots.

The world No. 3 is the first tennis player to take the challenge but stand by—he nominated Serena Williams to take it next.
