Just run through Wimbledon 1974 wikipedia page, I notice that 39-year-old Rosewall's draw was absolutely bonker.
4R: young big-serving Tanner, who upsetted Seed No.8 Ashe in 3R
QF: Newcombe, Seed No.1, US Open and WTC winner, undefeated on Wimbledon grass since 1970. Newk torched Rosewall in 1973 US Open in their most recent meeting.
SF: Smith, Seed No.4, Nottingham winner (giving Connors a bagel in final), undefeated on Wimbledon grass since 1972.
F: Connors, Seed No.3. We all know what happened.
The fact that Rosewall defied expectations, went through the toughest Wimbledon draw you can get between 1974 and 1979, and reached the final made his run even more impressive.
