I think they changed the grass TCBM. I'm sure when Timmy was still around and was to his disadvantage also.
Found this on another tennis forum
Yes it is radically slower starting at the 2002 Wimbledon. It was no coincidence that these things happened:
1/ Tim Henman noted that year how slow things were
2/ Two baseliners (thought agressive baseliners) made the final
3/ 7 time champion Sampras failed in the 2nd round (he was definitely serve and volley specialist then).
But even more they have done tests between 2003 and now the surface is even much slower than then (and 2003 was already much slower than 2001).
They have slowed it down by using a different variety of grass plus made the balls larger and more difficult to pass through the air quickly due to the compression in them.
Why have they done this? They were trying to get better grass that would last better. Unfortunately it has the result that a Clay Courter has been to the final every year since 2006 (with the exception of 2009 when he was injured), when there is no way this would have happened in 2001 and prior grass. No problem with said Clay Courter doing this - but I do believe that the tennis season has to be balanced between slow court and fast court tennis - and unfortunately fast court tennis has completely disappeared (example no indoor carpet left). There is only slow court tennis and medium paced court tennis left now.
My belief is that the grass was too fast pre-2002 (we just had serve fests in the 1990's), however, things have swung far far too much the other way.http://tt.tennis-warehouse.com/showthread.php?p=6660391
I'm well aware that they slowed the courts 2002. That was 10 years ago, I'm talking about now.
Just make them lower bouncing and a bit faster, accomodating present technological requirements as well.
If it helped a certain british player take wimbledon then it would be well worth it.
By the second week, particularly if it has been very sunny the courts wear out and it might as well be RG. Except it is even slower.
i agree its gone to far and something really should be done about it.
