Roger Federer shares the most tournament wins in a calendar year with a surprise star rather than Rafael Nadal or Novak Djokovic.
The Swiss superstar won 12 titles in the same year in 2006, including the Australian Open, the US Open, and Wimbledon.
Federer often contested records with Rafael Nadal and Djokovic, but there’s another star who’s won the same number of tournaments in a year as the 20-time Grand Slam winner.
The star only ever picked up one Grand Slam tournament, but he managed to capture 12 tournaments in 1995.

Thomas Muster equals Roger Federer’s record for most tournament wins in a year
Thomas Muster was impressive in the mid-1990s, reaching World No. 1 and winning Roland Garros in 1995.
His sole Grand Slam win was part of his best-ever season, which saw him lift another 11 trophies on the ATP Tour calendar.
The clay specialist won tournaments in Estoril, Barcelona, Monte Carlo, Rome, Sankt Polten, Stuttgart, San Marino, Umag, Bucharest, and Essen, with 11 of the wins coming on clay court.
| Player | Year | Number of titles in a year |
| Roger Federer | 2006 | 12 |
| Thomas Muster | 1995 | 12 |
| Rafael Nadal | 2005 | 11 |
| Novak Djokovic | 2015 | 11 |
While the tournaments were not as high-profile as the ones Federer picked up in 2006, Muster will always have his name alongside the great star.
Muster’s 12 wins put him one tournament above Djokovic and Nadal, who achieved 11 competition wins in 2015 and 2005, respectively.
Thomas Muster also holds a bizarre and unwanted tennis record
Muster was very much a clay court player, and the Austrian was known to struggle on other surfaces, particularly grass courts.
While Muster did achieve a semi-final appearance at the Australian Open, and a quarter-final appearance at the US Open, the Austrian didn’t achieve a single Wimbledon win.
The star exited in the first round on four occasions, including in back-to-back years between 1992 and 1994.
Muster never reached a grass court tournament final in his career, despite reaching 55 finals between 1986 and 1999.
