2013 Stockholm on indoor hard, 2014 Acapulco on outdoor hard, 2014 Bucharest on clay, and now 2014 Queen's on grass. Very impressive stuff from the 23-year-old. He is truly a threat on all surfaces. And it has all happened since he hired Roger Rasheed as a coach in October 2013. Really good work from Roger and Grigor! What do you think this means for the future?
