Ivan Lendl

Ivan Lendl ( Czech: [ˈɪvan ˈlɛndl̩]; born March 7, 1960) is a Czech–American former professional tennis player and coach. Widely regarded as one of the greatest tennis players of all time, he was ranked as the world No. 1 in men's singles by the Association of Tennis Professionals (ATP) for 270 weeks (fourth-most of all time), and finished as the year-end No. 1 four times. Lendl won 94 career singles titles, including eight majors (three each at the French Open and US Open, and two at the Australian Open) and seven year-end championships. He was runner-up at a further eleven majors, for a total of 19 major finals (among which a record eight consecutive US Open finals).

Lendl is the only man in professional tennis history to have a match winning percentage of over 90% in five different years (1982, 1985, 1986, 1987, and 1989). He leads the head-to-head against his two biggest rivals, with a 22–13 record against Jimmy Connors and a 21–15 record against John McEnroe. Lendl's dominance of his era was most evident at the year-end championships, where he holds a win–loss record of 39–10 and contested the final a record nine consecutive times.
