making 6 straight finals at a slam is amazing. im no hingis lover, but serena has never done that at any slam, and i'm pretty sure not many women have either.
as for seles winning in 1991 and still making semi finals in 2002, with 4 titles along the way, that to me is longevity.
Serena has 2 more titles than Hingis. 2 extra titles >>>>> 1 extra final (or 3 extra runner ups). The streak of 6 finals in a row is negated by losing 3 finals in a row, including 2 in a row to Capriati (
), and winning your last ever title at age 18.
Seles you have more point on than Hingis, which all but answers part of the thread question atleast, Seles > Hingis at the Australian Open. Hingis did do well vs Seles when they met there but that can just be the matchup, particular in light of prime Hingis even being owned by the likes of Capriati there as mentioned.
Graf is underrated by many as being part of the Australian Open greats. She missed the Australian Open 2 years she would have been heavily favored to win (1995 and 1996), and one she would have been a strong contender (1987 1992), and while it is different circumstances in part that is even more than for instance Seles missed (1994, 1995, and a lesser contender in 1997 and 1998). Despite that she still won 4 titles and lost a 3 set final to Seles in the 5th. That is more finals and same # of titles as Seles, and 1 more title and only 1 less final than Hingis. Hingis unlike Graf and Seles had the good fortune of being healthy and able to play each year, and still could not amass more success than that. It is hard to even say Graf benefited much from the Seles stabbing when Graf hardly did anything at the Australian Open after the Seles stabbing anyway, missing most yeas injured, or playing injured and getting a poor result on other occasions. The Australian Open after 1994 was just a write off for her anyway.
