I have been playing doubles in a league again this year. It's been years since I played doubles. I noticed immediately, the past three weeks, that I have a glaring weakness on a 1 HBH topsin servcie return. I hit a very decent 1HBH normally, but noticed it is really missing on the return where I am forced to hit back crosscourt! I would try, but it was grossly uncomfortable. It was so bad I was thinking of using a 2HBH, but forget that...I spent YEARS developing this 1HBH. Playing around with my racket today, going through the motions of service return, I think I found the big problem. I have been staying squared up toward the net on the return for topspin backhand. I could see immediately that this puts the shoudler and arm in a terribly weak structural position. I think I have been completely forgetting the unit turn here...and arming at the ball, which is why it 'feels' so weak and just plain terrible. Validate me here please...but I think the solution is the unit turn, and keep my shoulders closed through impact, which puts my shoulder and arm in it's strongest structural postion. It seems like such common sense, I am actually embarrased to even bring it up. I guess I just got into the habit of slicing back hard services, but in doubles, this is a 50/50 thing as the net guy is salivating up there on my slices!
