Thiem was primarily an aggressive baseline player, adept at defending as well. His groundstrokes were solid on both wings, with a heavy forehand and a tenacious, powerfulsingle-handed backhand. He was one of the few ATP players to use a single-handed backhand.[277] According to Thiem, he changed to his single-handed backhand at the advice of his coach.[10] His backhand effectively handled high bouncing balls, which are a big problem for many conventional single-handers.
