He became the first man in the Open Era to win Canada Masters, Cincinnati Masters and the US Open in the same year, which he achieved in 1998; this achievement has been dubbed the American Summer Slam. To date, only two players have followed this feat: Andy Roddick in 2003, and Rafael Nadal in 2013. Rafter is the third man in the Open Era to reach semifinals or better of every Grand Slam tournament in both singles and doubles, after Rod Laver and Stefan Edberg, and remains the last man to date to accomplish this. Rafter is also the only player to remain undefeated against Roger Federer with at least three meetings. He is also the only player who has a winning record against the 20-time Grand Slam winner on all the three main tennis surfaces: hard, clay and grass.
