After a stellar year, young tennis player Dominic Thiem made his debut at the year-ending ATP World Tour Finals which started this week at London’s 02 arena. In spite of struggling during the latter part of the season, his four titles earlier in 2016 and a career high ranking of 7 enabled the 23 year-old to become the youngest player in the elite eight man field. Known for his aggressive baseline play, heavy ground strokes and a rare and impressive single-handed backhand. After losing, but taking a set off former No.1 Novak Djokovic in his opening match, Dominic showed his much heralded potential with a win over the stylish Frenchman Gael Monfils in his second pool match to keep his hopes alive of making the semis later in the week. I caught up with ‘The Dominator,’ as he’s nicknamed when he arrived from the clipper at the Greenwich Peninsula pier on Monday. The likeable and humble Austrian liked the drawing and was happy to sign and dedicate it for me.
