Thomas Muster (born 2 October 1967 in Leibnitz, Styria, Austria) is a former World No. 1 tennis player from Austria. One of the world's leading clay court players in the 1990s, Muster won the 1995 French Open and at his peak was known as "The King of Clay." In addition, he won eight Masters 1000 series titles, placing him seventh on the all-time list. Muster is one of only three players to win Masters titles on three different surfaces (clay, carpet, and hard court).
When Muster was on the ATP Tour in the Twentieth Century, he wore Lotto clothing. From 1986 to 1993, Muster played with the Head Prestige Pro 600 racquet. In the summer of 1993, Muster switched for a few months to playing with the Head Prestige 600 racquet. In 1994 and 1995, Muster played with the Head Pro Tour 630 racquet. At the start of 1996, Muster switched to using a Kneissl racquet, which was closely modelled on his old Pro Tour 630. At the start of 1997, Muster switched his racquet again to the white Kneissl Tom's Reach Machine racquet, which had a longer handle and a 28 inch frame. In 1998, Muster used his Kneissl Tom's Reach Machine racquet on hardcourt, grass and carpet, but went back to his old 1996 Kneissl racquet on clay. When Muster played on the ATP Champions Tour, he used the Kneissl Tom's Reach Machine racquet.
When Muster came back to the ATP Tour in 2010, he used the Head Pro Tour 630 racquet, then switched to the Babolat AeroPro Drive GT racquet, and then went back to the Head Pro Tour 630 racquet again before playing his last matches in late 2011. Muster always wore Adidas clothing in his matches in 2010 and 2011.
