If you watch professional tennis at any consistent clip, tweeners probably don't excite you anymore. Much like the NBA Slam Dunk contest and the way we've become so blasé with incredible dunks these days, guys hitting shots between their legs while running full speed doesn't feed our addiction like it used to, and that is one of the reasons that the shot you are about to watch is so amazing.
Nick Kyrgios is a 19-year-old Australian that got matched up against Rafael Nadal on Centre Court at Wimbledon. Re-read that sentence to yourself again if you need it, because it makes this shot he pulled off against Nadal in the second set of their fourth-round match all the better.
It's a tweener with attitude, a simple "nah, I'm good" feel to it when Kyrgios calmly plops it back over the net for a winner against one of the best tennis players to ever lace up a pair of trainers.
Kyrgios went on to win the match, mostly because of shots not like this one at all. He did it with power and more power, but this shot, the simple flick between the legs, will be the shot you'll remember from this incredible upset at Wimbledon.
