LONDON (AP) Dominic Thiem landed one too many punches even for Novak Djokovic to handle.
In a seesawing crowd pleaser that lasted nearly three hours and featured a handful of momentum shifts in the third set, Thiem outlasted Djokovic 6-7 (5), 6-3, 7-6 (5) on Tuesday to become the first player to advance from the group stage at the ATP Finals.
"It was maybe the best match I ever played," said Thiem, a two-time French Open runner-up. "It was a real classic and epic match which will happen from time to time at these big tournaments. It had everything - He was up; I was up. He was playing amazing points. Me, I was playing amazing points."
