Degrees of Seperation - H.L Doherty to Roger Federer - do it in less than 6 Jumps?

[timnz]

I wondered what the smallest number of jumps you can do from H.L Doherty (number one around the turn of the 20th Century) to Roger Federer. Include the matches played.

1. H.L Doherty played Brookes (1905 Wimbledon final)

2. Norman Brookes played Tilden (1919 US Open - Tilden won 1-6 6-4 7-5 6-3 - Brookes was 41 years old against a 26 year old Tilden - great players still show greatness late in their careers)

3. Tilden played Pancho Gonzales (in 1952 - Gonzales won 6-1, 6-2 - Tilden 59 years old!)

4. Gonzales played Connors (in 1971 - Pacific Southwest final - Gonzales won 3–6, 6–3, 6–3 at 43 years old!)

5. Connors played Sampras (in 1992, Atlanta Quarter finals - 7-6(4), 6-2 to Sampras - not a bad score by nearly 40 year old Connors)

6. Sampras played Federer (Wimbledon 2001 - Federer won in 5 sets).

Can anyone do it in fewer than 6 steps?
