Probably beating Steffi Graf's record for most grand slam singles wins in the open era. Her new best achievement will be beating Margaret Court's record for most grand slam singles wins ever. Hopefully she can do it.
It is one and only "ROGER FEDERER"
depends on if you only mean singles play or singles/doubles in toto A female holds the record for both, considering the "open era" and excluding junior titles Singles titles -Margaret Court (24 titles) singles/doubles - Margaret Court (62 titles)
Roger Federer currently holds 16 Grand Slam titles, the most collected by a men's singles player to date.
The two most prolific are Australian "tennis stars". In terms of singles Calendar Grand Slams, Rod Laver has won two: in 1962 and 1969. Overall, however, Margaret Smith-Court has won the most Calendar Grand Slams of the lot, as she achieved the feat in singles in 1970 and achieved mixed doubles calendar Grand Slams on two or three other occasions. I suppose you might say that makes her the top star of true Grand Slam-making! In terms of Slam events, she has been awarded a total of 64 - 62 she won outright and two she holds jointly when no final was able to be played at the event.
