Wrong, it was Hingis who kept her from titles that year and in 1997. She was like Roddick to Federer.
Sorry but had to laugh at this one. What big titles would she have won without Hingis pray tell. Wimbledon 97? Novotna would have spanked her silly, she owned Anna, heck Anna couldnt even beat a choking Novotna on CLAY at next years French when she had improved more, and was far and away a better grass player (should have beaten Hingis in the final too but choked). Australian Open 98? She might have reached the quarters then got spanked by Pierce who made her eat a bagel at the same event the next year. No others she met Hingis at. Even with as weak as the field was in 97-early 98 there were still so many players better than Anna. Davenport, Novotna, Coetzer, Martinez, Sanchez Vicario (though she was a decent matchup for Anna I will admit), Venus, young Serena, Pierce, Seles, Majoli on slower courts, Spirlea. She lost the vast majority of matches to almost all those women, in addition to posting weaker results on tour. She was not going to take over the tour or win anything big even without Hingis. Had Hingis not existed this is who would have won her slams, and maybe some she didnt win but factored in:
1997 Australian- Pierce or Fernandez
1997 French- Seles (I think she beats Majoli probably)
1997 Wimbledon- Novotna, 110% for sure, she crushes Sanchez or Kournikova in a one sided final
1997 U.S Open- depends on the draw, could be any of Novotna, Davenport, Spirlea, or Seles, highly doubt it is Venus. If Jana somehow avoids Davenport or doesnt choke like the end of their quarterfinal probably her.
1998 Australian Open- depends on the draw. If Davenport avoids Martinez than her, if Venus avoids Davenport than her, if neither of those things happen then definitely Pierce.
1998 French- depends on draw, but quite likely Seles. I think her loss to Sanchez in the final here was a bit flukish with how it played out, and I doubt Sanchez even reaches the final with any other draw this year. Could also be Venus.
1999 Australian- Mauresmo or Pierce, although if Davenport doesnt run into buzzsaw version of Mauresmo in semis could be her.
Either way Kournikova does not enter the possible winners of any of those.
