#4 Iva Majoli
The first ever Croatian athlete to win a Grand Slam singles title - male or female was Iva Majoli. Having reached a career-high ranking of world number 4 in the WTA rankings - the highest that a Croatian player has ever reached, she won the 1997 French Open denying Martina Hingis a calendar Slam that year. The same year, she made the quarterfinals at the All England Club losing in straight sets to young sensation Anna Kournikova.
In her career spanning 13 years, she won 7 WTA singles titles. A series of shoulder injuries affected her form and her ranking plummeted. She was finally forced to retire in the summer of 2004. She was later made the non-playing captain of the Croatian National Fed Cup Tennis Team in 2012. In 2015, she made a one-off comeback after 11 years, competing at the Kremlin Cup.
