years and he remained under Ektelon sponsorship through his entire playing career. In Memphis, in January 1972, Muehleisen played perhaps his most famous match versus Paul Haber then the world champion handball player. Haber played with his hand and Muehleisen with a racket, but the match was played with a handball, which was smaller, faster and harder than a racquetball. The match was played to a standing room only crowd and billed as a contrast in personalities. Sports Illustrated described Haber as "a man who takes a drink or eight, [and] has been known to wink at a girl", characterizing the match as "Mr. Clean versus the Devil" and making the outrageous claim that "There hadn't been anything remotely comparable in, say, a millennium or two, at least not since Spartacus and the slaves made it nets and tridents against swords and shields." Muehleisen claimed that he had an advantage due to the superior power of the racket. Haber claimed to have the advantage because the ball was best suited to being struck by the hand. Muehleisen won the first game easily, lost the second, and lost a very tight tie-breaker. Video of this match still exists along with Haber's commentary. Muehleisen and Haber played a second time on September 17, 1972 in Long Beach, California. According to Sports Illustrated, Haber was characteristically late to the court due to a gin rummy game that went into overtime, after which he couldn't find his shoes. Again they split the first two games with Muehleisen winning the first and Haber the second. But this time Muehleisen won the third to take the match, 21-9, 18-21, 21-8,. Racquetball grew tremendously during Muehleisen's era, though it remained a strictly amateur sport during his prime. In its Fall 2009 edition, Racquetball magazine ranked Muehleisen as the "best player never to win a professional tournament" (page 31). When he turned 40, 'Dr. Bud' shifted to age group competition and continued to win national titles in age group divisions through the Golden Master's (55 and over), amassing a total of 41 national championships and numerous international championships. He also won many doubles championships both in age group and open competition, and won open paddleball and outdoor racquetball national doubles championships with Brumfield. In 1980, Muehleisen was elected to the San Diego Hall of Champions, the premier sports museum in San Diego. In 1994, USA Racquetball'', the official
