Aside from the greatest rivalries of all time like Federer-Nadal, Djokovic-Nadal, Sampras-Agassi, or Borg-McEnroe, how about are some underrated competitive rivalries? It can be lopsided too.
Serena-Justine Hénin 8-6.
Female 1-hander GOAT
Not taking anything away from Serena, but she definitely benefited from Henin’s early retirement
Sabattini and Graf. 29-11 in Steffi’s favour but very competitive matches with Sabattini winning 5 in a row at one point with a US Open final win just before that
I think it’s a pretty well known rivalry, but I didn’t think Becker is 25-10 against Edberg. 19 of their meetings were finals btw.
Barty-Sabalenka. That was a great rivalry
Murray 13:9 Wawrinka
to make off a more recent one, sascha vs. bweh being 5-3 for sascha with rublev winning the last three
