5) Bjorn Borg, 1979 – 84-6 (93.3%)
The dominant force of the late 1970s, ‘Iceman’ Borg won 84 matches and tasted defeat just six times in 1979 – arguably the greatest year of his legendary career.
The Swede won 13 titles that season, including at Roland Garros and SW19, and reached a further final – while finishing the year as the world No 1.

Federer won 12 titles in 2006, the most he ever won in an individual season, and he lost just five matches across the entire year.
Of his 92 match wins, 27 came at the majors, winning three of the four Slams while tasting defeat in what was his first French Open.
Federer won 94.8% of his 2006 matches, the fourth highest of the Open Era – but not his best result.

The highest win percentage of the 21st century, Federer won a staggering 95.3% of his matches in 2005 – holding an 81-4 win-loss record.

With a 95-4 record for the year, Connors achieved a win percentage of 96% – the second-best by a man in the Open Era.
1) John McEnroe, 1984 – 82-3 (96.5%)
Undoubtedly the greatest season of McEnroe’s career, the US star’s 1984 is also among the greatest seasons ever produced by a male player.
McEnroe lost just three times in 85 matches across 1984 and won the Wimbledon and US Open titles for the final time, alongside reaching his sole French Open final.
With 13 titles to his name across the year, his win percentage of 96.5% is a record unlikely to ever be broken.
