See Novak Djokovic's new no-look shot

Fourhand is the Daily Spin's occasional roundup of various hits and misses on tour.

LOOK, MA, NO EYES  Novak Djokovic hooked a nifty, no-look backhand in practice recently that 1) proved there's just no one who matches up to him right now in tennis, and 2) led to a Bryan brothers-esque chest bump with one member of his team.

That's neat and all, but Agnieszka Radwanska is here to say something, not with words but rather with her own weapon, about racquet-based plagiarism.

TIME TO SAY GOODBYE  After 17 years on the ATP World Tour, Michael Russell, a super-fit terrier of a veteran at age 37, retired from pro tennis upon his loss at the U.S. Open. One of the most well-liked gents on tour, he deserves a proper sendoff, and he gets it in an ATPWorldTour.com video. You simply have to admire a guy who appears to have held onto the tournament towel of at least every major event he played in (32 for him, by the way).

READY FOR THIS JELLY  If you've ever wondered what jelly would look like when thrust rapidly through the strings of a tennis racquet (and you haven't), the Slow Mo Guys are here to show you. That's "jelly" as the Brits know it, by the by. Suffice it to say, 4.5 million viewers can't be wrong—and call me crazy, but there's unexpected beauty in this video. (And the winner, in the end, is Wilson Tennis.)

HE SAID NO  You can ask, more than once even, but NBA baller Sasha Vujacic has no interest in answering anyone's questions about his failed engagement with Maria Sharapova, which ended in 2012.
