The technology has led to serve and volley being close to extinction and the dominance of baseline play. That doesn't mean that different courts all have the same conditions, just that baseline play predominates everywhere. You're misunderstanding me. There are still clear differences between the surfaces, which is why Nadal dominates on clay but not on hardcourts for example, but that doesn't change the things I've said about the technology and the fazing out of carpet courts being the main factors in today's tennis play on the tour (i.e. baseline play with authority) being different from the tennis style on tour in past eras. Because there are clear differences between clay and hardcourts. I never suggested otherwise. I'm sorry if you got that impression, but that was never my point. It doesn't seem that we are. Most of the time, yes. The modern technology makes it harder to get off the baseline. The modern technology compels players to stay on the baseline the vast majority of the time, because of the power, spin, depth and authority in the rallies in today's game. This doesn't change the fact that the courts are different at each tournament, or even different courts at the same tournament. But baseline play does now hugely predominate at all tournaments, and it's mostly because of the technology in today's game. What happened in Madrid this year was down to the surface, it was ridiculously slippery.
