Here’s Rafael Nadal having a high intensity training session with Frenchman Lucas Pouille. Nadal is currently world no. 1 and a top favourite to win the 2018 U.S. Open along with Roger Federer and recent Cincinnati winner Novak Djokovic. Former champion Juan Martin Del Potro is always a threat when healthy and Alexander Zverev just added Ivan Lendl to his team so he may bring something new.
Rafa looked sharp and hardly missed during this practice. As often noted during his practices, he is finishing his forehand through the ball and with his arm wrapping around the opposite shoulder as opposed to the helicopter finish you see in matches.
