Wasn't the biggest joke ever Davenport being #1 in 2001
Capriati won the Australian Open and the French Open (SF at the other 2). Venus won Wimbledon and the U.S. Open (SF at the AO, 1st round at the FO). And yet, Davenport was #1 with SF at the AO, n/a at the FO, SF at Wimbledon, and QF at the U.S. Open.
Jen was 56-14 that year, with 2 GSs, 3 overall titles, and great play at all 4 GSs. Lindsay was 62-9 with 7 titles, but she did just okay at the Slams.
This year, Henin-Hardenne won the AO, but didn't play much. Same with Sharapova (b/c of the rules) at Wimbledon. And Kuznetsova and Myskina were very inconsistent.
