This is a great slice backhand video from Patrick Mouratoglou. He had coached Serena Williams some back in the day. He’s turning out tons of content and has over 300,000 followers.youtu.be/eaqsJy4eNQM
The slice backhand is an art form. As you improve the shot you’ll be able to drive it through the court, use it as a defensive lob, approach shot, drop shot, angle, and return of serve. I must hit hundreds of these everyday when teaching.
