If they do then it is pretty low key.
I remember it started shortly after the golf seniors tour which was and still is quite popular, but the tennis version petered out pretty quickly. You can see how much slower and less fit the players are. Actually, I think golf is the only sport where a seniors tour would be a viable entity. The reason for that is that there is very little athleticism in golf. As such watching a 55 year old hit a ball is not much different than a 25 year old hitting a ball. In other sports you move slower, you are not as strong, you can't jump as high, hit or throw the ball as far, you can't dive to make a catch etc. etc. and that diminution of athleticism is evident to everybody and is actually kind of sad to watch. You don't see that loss of athleticism in golf because it is basically a skill, swinging a club. All they have to do in golf is make the holes a bit shorter and the players can stick it as close to the pin as they did when they were in their prime. So there is still the same drama in golf unlike other sports. Watching a 55 year old playing tennis is dull.
