PARIS, June 4 (Reuters) - As if by stealth, Dominic Thiem moved into the quarter-finals of the French Open on Sunday with another quietly devastating performance.
The Austrian sixth seed swept aside Horacio Zeballos 6-1 6-3 6-1 to book a last-eight clash with either Novak Djokovic or Albert Ramos-Vinolas.
On form, Thiem is positioning himself as the main threat to Rafa Nadal winning a 10th crown here. The pair could meet in the semis. (Editing by Rex Gowar)
