Borg 3-0 Vilas for the season, including a win in the semis of the Masters. Vilas lost in the final of Australia start of the year, to Tanner, and had a 3r defeat at Wimbledon. To Billy Martin.
Borg won 11 events that year himself, obviously more selective in his schedule than Vilas, didn't play as many soft tournaments.
Borg would have been a big favourite to beat Vilas at RG. Borg whooped Vilas in their clay court meetings just prior to RG. Borg missed RG due to World Team Tennis. Not Vilas' fault, he did what he had to do. Still doesn't take away that Borg was no.1 on clay and a clear favourite for RG.
Vilas never beat Borg in a GS event.
Vilas 'lucky' Borg missed RG in 77.
Borg superior all surface player to Vilas in 77 or any other year for that matter.
