When Dominic Thiem was growing up, he always dreamt of winning a Grand Slam title. After turning that into a reality by triumphing at the US Open, the Austrian doesn’t want the victory to change who he is off the court. The 27-year-old became the first player to lift his maiden major trophy since Marin Cilic emerged victorious at the 2014 US Open. Between the 2017 Australian Open and this past fortnight at Flushing Meadows, only members of the Big Three — Roger Federer, Rafael Nadal and Novak Djokovic — earned Grand Slam glory.
