#2 Most singles match wins in a year
Guillermo Vilas holds the record of most singles match wins in a season. The Argentine left-hander compiled a staggering 136 match wins from 150 matches during the 1977 season.
It was a recurring theme in the 70s and early 80s for a player to win over 100 singles matches in a season. Prior to Vilas, Ilie Nastase of Romania won 125 matches and lost 13 in 1973. Ivan Lendl won 110 matches in 1980, and 106 in 1982.
Federer's 92 wins in 2006 is the 7th best single-season win tally in the Open Era. After 2006, Federer's highest win-tally of 73 came in 2014.
With the Swiss maestro playing fewer tournaments the last four seasons than he did in his prime, this record seems far away from Federer's grasp.
