50+ Win Seasons
I know there are at least 4 players in 2012 who have already earned 50+ wins this year
Kerber: 56-17 (2 titles - Paris [Indoors], Copenhagen)
Azarenka: 53-7* (4 titles - Sydney, Australian Open, Doha, Indian Wells)
Serena: 51-4* (5 titles - Charleson, Madrid, Wimbledon, Stanford, Olympic Games)
Radwanska: 51-15 (3 titles - Dubai, Miami, Brussels)
*still alive in US Open
How many players have had multiple 50+ win seasons?
I know Kim had like a 90 win season in '03 and I'm sure Caroline and Jelena have racked up a few too.
