Donna's first WTA title at the 2014 Malaysian Open
The happiest moment in Donna's life was when she won her first WTA tournament Malaysia Open held in Kuala Lumpur in April 2014 at the age of 17. In her career so far, having played three finals, the highlight was the victory in this final over the world number 11 Slovakian tennis player Dominik Cibulkova with a score of 5–7, 7–5, 7–6.
The second WTA title followed at the 2017 Nottingham Champion
"Training more than ever before and fully enjoying tennis, with everything else that fell into place" - as Donna stated, resulted in a victory over world number eight Johanna Konta in the final of the WTA Nottingham Champion Open held in Great Britain in June 2017. She won her second WTA title with a score of 2-6, 7-6, 7-5.
The third WTA title at the 2021 Courmayeur Ladies Open tournament is a confirmation that Donna's tennis career continued with development.
The third trophy and WTA title in her career so far followed in October 2021 at the Courmayeur Ladies Open tournament in Italy, which was part of the WTA 250 tournament.
After surgery on her right knee in February and the recovery period, Donna returned to the top 70 tennis players in the world with this tournament in an impressive way, without losing a set (7-6(3) 6-2) and winning over Denmark tennis player Clara Tauson.
At the WTA 500 San Diego Open in November 2022, Donna Vekić defeated the world's fifth-ranked Arina Sabalenko in the quarterfinals with a score of 6-4, 6-7, 6-1, and thereby won her first semi-final in 2022 and in her career so far.
That ensured her return to the top 50 tennis players in the world, precisely at 47th place.
The 2021 Olympic Games in Tokyo positively motivated Donna
"It's a special feeling when you not only representing yourself, but your homeland at such a big event. This is definitely a new experience in my career so far." - Donna said as the proud representative of Croatia at the Olympic Games in Tokyo, Japan, in July 2021.
Having reached the third round after marathon matches in which she first won against the French Caroline Garcia in the first round, and the third tennis player in the world the Belarusian Aryne Sabalenko in the second round, she did not continue her Olympic story.
Despite a knee problem and a sore shoulder, she came close to winning in the third round, but she points out that she will be back again at the next Olympics.
