Thomas Muster (Apr.l-June 1995)
Known best for his play on clay, the Austrian had his best season in 1995. Beating Michael Chang for the French Open title -- his only Grand Slam -- marked the highlight of Muster's streak. Before going off for 35 straight wins, all on clay, Muster had lost four straight matches, none on clay.
In all, Muster made 14 finals in 1995 and won 12 of them (11 clay).
