Dominic Thiem thought winning his first Grand Slam title at the U.S. Open would make him calmer in the tensest moments of the biggest matches. The No. 3-ranked Thiem ended Djokovic’s bid for a record-tying sixth ATP Finals title, coming through 7-5, 6-7 (10), 7-6 (5) after trailing 4-0 in the concluding tiebreaker. ”What he did from 0-4 in the third-set tiebreaker was just unreal,” said Djokovic, a 17-time Grand Slam champion.
