ITF World Champion is based on
1. Grand Slam
2. Davis Cup / FED Cup
3. Olympic Games
Myskina was ITF World Champion 2004 because she was
1. Roland Garros Winner
2. Member of FED Cup Winner
3. 4th in Athens Olympic Games
Likewises, Becker was ITF World Champion 1989 not only because of his dual titles in Wimbledon and US Open (even though 5 titles), but also his winning Davis Cup.
Lendl was Year End NO.1 of 1989 without any arguement (10 titles w/ Australian Open, runner-up of US Open and SF of Wimbledon)
