Going by sheer numbers one would have to give Graf the edge between the two though with Sele's tragic assault we can never get a final picture of how that duel might have ended.
From 1990 through April 1993 Steffi Graf was limited to winning only 3 of the major singles titles in women's tennis (3 out of 16 played during this time) ... Monica Seles, as a 2-handed teenage phenom, won 11 of these 16 singles titles (including 2 of the 5 in 1990 .. 4 of the 5 in 1991 .. 4 of the 5 in 1992 .. and the only 1 prior to the stabbing in 1993).
Anyone who wants to belittle the knife stabbing -- or brush it aside as if it had no significance -- has all of this to overcome.
No question about it, Monica Seles was easily the best player in women's tennis for the first half of the 1990s.
