Chris' depth off the ground kept Martina pinned at the baseline. And Chris also played a strategically brilliant match, coming in at every opportunity and taking that away from Martina. At one point during the match the commentators claimed Chris had been to the net more than Martina. I don't have stats, so I can't corroborate, but my sense from watching was that was true, at least halfway through the match. Martina picked it up in the 2nd set, and came in more. But at the start of the third set Chris again took control of that match.
Chris was playing with her wooden racquet, Martina with the Yonex graphite. Chris could still match Martina's power with her stick. I was also impressed with Evert's variety. On a number of occasions she hit her two handed slice backhand, knifing the ball hard, low, and deep. There is no player today who could ever do that!! Even when you see Serena or other two handers try a slice, it is rarely an offensive shot, more of a change of pace. Chris hit aggressive two handed slice shots to her advantage. And her overall variety, her ability to hit accurate groundies off an abysmal surface - you could tell how patchy and uneven the grass was (it seemed much worse than Wimbledon) - her court sense throughout was marvellous. No other woman (and yes that includes the pesky and inferior from the baseline Tracy Austin) was able to challenge Martina on grass by mixing it up and playing as smartly as Christine Marie Evert!
I think it was on this thread a few pages back that I wrote that Chris's best two patented shots, in my view, were the forehand crosscourt dropshot and the forehand sidespin drive down the line. The holy trinity in the arsenal of St Christine Marie Evert of Fort Lauderdale, patron saint of multiple divorce and remaining cool when receiving service at triple-match-point down, is in my opinion Chrissie's double-handed slice APPROACH SHOT (!!) to the net.
I think there was a separate thread at one time on the 1982 AO final, I remember posting in it, so won't add anything else here, because Dennis has captured it all more or less in a nutshell. I was also impressed at Chrissie's speed about the court. She very much wanted to win this after losing such a tight match the year before to Martina, and this match shows very well why, I believe, ironically, grass was one of Chris's best surface. Her groundshots were so vicious at the best of times, with the sidespin sending it shooting away from the player like a guided missile, which grass made even more effective. Her overhead was also very effective in that match - actually, she was serving at 5-1 in the final set and the match was never really in any doubt. I see this match as the final hurrah of the vintage wooden-racket-playing ice-maiden mastermind.
