Serena Williams, currently the top-ranked woman in her sport, is no mere tennis player. She is a tennis technician, capable of firing a tennis ball back at her opponent with staggering precision and force. The guys from Dude Perfect, a popular, sports-themed YouTube channel built around incredible trick shots, recently had an opportunity to witness Williams’ mastery of tennis up close when she stopped by to participate in their latest video. “Tennis Trick Shots” is seven minutes of pure athletic awesomeness, a testament to just how good Williams is at her sport. She can pop a water balloon with a tennis ball. She can knock a canister off a man’s head, William Tell style. She can hit a moving target. And not one of the five members of the Dude Perfect team can even score a single point off her. She even excels at completely ridiculous challenges, like using an oversized novelty racket to hit a tennis ball into a basketball hoop.
