I have recently found a new hitting partner at the outdoor courts in my town. We have played a handful of times over the last several weeks. He is an older gentleman and has limited mobility in one of his legs. I enjoy hitting with him because it allows me to groove my baseline game and groundstrokes with rhythm and good pace. However, we do not play singles matches because of the leg issue and I also find that I am hitting most balls directly back to him. It's fun playing with him because it gives me a much different game than the ladies I play with. Our practice sessions are loosely structured. So far we have played points cross court to help me with my doubles game. We usually spend time hitting from the duece/ad sides and then I practice my serve and he returns. He also blasts a series of balls while I am at net for volleys. We usually end up playing for about 90 minutes. I am happy to have found such a fun, occasional hitting partner. Is there anything else we can focus on to make it a quality practice session? Serious replies only..thank you!
