I've been playing for years and tend to hit the ball at it's highest point if possible and I'm just not used to moving up and taking the ball on the rise. Tonight I played with a 16 year old girl for the 2nd time this month. The first time we played I won 6-1 since she couldn't handle the serve. But her groundstrokes were really solid and she's excellent at taking the ball on the rise. Tonight she was handling my serve a lot better and her groundstrokes were just awesome, so smooth and precise, she won 6-1. Her game has made me realize that if I'm going to progress to the next level, I will need to start taking the ball on the rise and be a lot more aggresive. So what should I be doing out there to make the transition? What are the technical steps I should be working on?
