wow Borg at 1978. over 80% and gave up less than 30 games in 21 sets???!
That's never gonna get beaten. Safer record than any Federer record even
People serve so great these days. It must be impossible to keep the average that low. 29/21 average 1,4 games per set given up
Today keeping opponents to under 40 games in 21 sets is borderline impossible so Nadals 41 in 21 sets in 2008 is was very close to 40. But not even close to Borg's 29.
