Seven years ago, former World No.2 and 2015 WTA Finals champion Agnieszka Radwanska turned heads - including her own! - as she pulled off an unforgettable no-look volley that required all the flair reflexes and reflexes that made her a star.

Taking on Kirsten Flipkens - herself no stranger to impressive trick shots - in the quarterfinals of the 2013 Miami Open, Radwanska was in the midst of battling from a set down to defeat the future Wimbledon semifinalist, turning the tide with the help of shots like that. The point was immortalized on the official WTA YouTube channel, where it has earned top video views over 3.9 million.

"I think you cannot really practice these kind of shots," she mused last fall at the WTA Finals Shenzhen following her 2018 retirement. "I couldn't really play powerful tennis like the others. I always had to find the other way to win matches. I think the touch was my escape from those players who killing the balls."
