Stanislas Wawrinka has added Dani Vallverdu to his coaching team for the grass-court season.
The 34-year-old three-time Grand Slam champion announced the addition on social media, saying he will also keep working with his regular coach, Magnus Norman, and his hitting partner. Vallverdu will likely appear courtside next week at the ATP event at Queen's Club.
