Top 7 World No. 1 male tennis players who have not completed a Career Slam

#3. Jimmy Connors

Connors never won a French Open

Regarded to be one of the greatest players in the history of the sport, Jimmy Connors was known for his powerful two-handed backhand and his service return. Connors was World No. 1 for a then-record 160 consecutive weeks and a total of 268 weeks overall.

Having won 109 Career Singles titles, Connors won eight Grand Slam Singles titles that included an Australian Open in 1974, two Wimbledon titles in 1974 and 1982, and five US Open titles in 1974, 1976, 1978, 1982 and 1983.

However, the one Grand Slam that eluded him was the French Open with his best performance being semi-final appearances in 1979, 1980, 1984 and 1985.The 1979 Roland Garros was the first edition of the Roland Garros where Connors had crossed the second round. The second seeded Connors was up against unseeded Paraguayan Victor Pecci in the semis who beat him in four sets.

The following year, Connors again reached the semi-finals; this time seeded third in the competition. In the semis, Connors faced 1977 Australian Open champion Vitas Gerulaitis. The match was a highly contested battle which lasted for five sets with the Lithuanian-American triumphing over Connors 6-1, 3-6, 6-7, 6-2, 6-4.

After three successive quarter-final appearances in the following years, Connors reached his third French Open semi-final in 1984 where he faced top-seeded John McEnroe. McEnroe comprehensively beat him in straight sets.

His last appearance at a Roland Garros semi-final came in 1985.

This time, Connors faced defending champion Ivan Lendl in the semi-finals who thrashed him 6-2, 6-3, 6-1. Even though Connors won the US Open when it was played on clay court once, he was never able to produce his best at the French Open which eventually denied him a Career Slam.
