This is from memory: Davenport does have a quote in the press and/or a video somewhere in 1999 where she speaks well of Graf's record. However, I think that she also had a quote that was along the lines of "It seemed that every time I won against Steffi, she had an injury." I can't remember if the quote was longer or if the press framed it in a snotty way, but it came across at the time as being unwilling to come up with a real positive take on Graf's career.Agreed.
Why didn't she get along with Graf? For whatever reason I recall some bad blood here-nothing major-but the two most definitely were not warm and fuzzy.
Sadly, Steffi did have issues during many of the Davenport matches. At Indian Wells in 1998, she couldn't finish the match. At Stanford that summer, she cramped badly in the third set and may have had the trainer out before losing by a break. At the year-end event in '98, I think there was a leg injury that may have also required work from the trainer. Even getting into 1999, an inside source claimed that Graf was in the hospital almost all night before her Sydney loss to Davenport... I think it was for an illness and/or IV treatment... and then, at Wimbledon, Graf's injury forced her out of the mixed doubles, though she did play the singles final. It would have been nice to have seen those two play matches when both were healthier.
I don't know much about Graf's feelings towards Lindsay, but I did read that she was subdued and deferential after the Wimbledon match in respect to Davenport's accomplishment even though Graf knew it was the end of her time there.
Hope this helps.
