Hey guys, Im playing a lefty with a tremendous serve. If he goes for hit flat his serve exceeds 140mph. But he usually had less than 50% with this serve, so I could handle it and sometimes i could just block it back. However, recently he changed his grip and now his serve is way slower probably around 120mph (still ridicolously by rec standard) but there is a ton of spin on that. If I attempt to block it the ball now will just randomly jump off my raquet, plus his serve percentage went way up about 70% or more. What can I even do? The only thing is his everything else in his game is really bad + he cant place his serve well. Any advice how to return that serve? I already stand back like 10+ feet behind the baseline.
