Croatia's Donna Vekic has announced that she will be working with coach Torben Beltz for the 2018 season.

"The next season is nearly upon us and I can’t wait to start working with Torben Beltz as my new coach," said the World No.56 in a statement.

"2017 was one my best years so far on the tour as I broke the Top 50 and I won my second WTA title; I am eager to do even better with Torben. It's a great opportunity to learn from one of the best coaches and I look forward to this new collaboration."

Vekic enjoyed an excellent grass-court season, winning the Aegon Open in Nottingham by beating top seed and British favorite Johanna Konta in the final.

Beltz coached former World No.1 Angelique Kerber to the 2016 Australian Open and 2016 US Open titles.

"I am very excited to work with Donna," added Beltz. "She has a lot of potential and I am sure we can achieve good results together."
