About Slobodan Živojinović
Slobodan "Boba" Živojinović is a Serbian former professional tennis player who competed for SFR Yugoslavia. He reached his highest singles ATP ranking on 26 October 1987, when he became world No. 19. Živojinović was known for his size that made him the original big-boom server before Goran Ivanisevic. Over the course of his career, Živojinović amassed an overall singles record of 152 wins and 139 defeats. The right-hander won two career singles titles (Houston, 1986 and Sydney, 1988), as well as eight doubles titles. His ace total in a match often became difficult to overcome and players did not look forward to competing against him. Živojinović's most notable Grand Slam results were two semifinals.
