Dominic Thiem has fought past tennis world number one Novak Djokovic to reach the title decider at the ATP Finals.
Djokovic saved five match points but the Austrian recovered from a poor second-set tie-break to win 7-5 6-7 (10-12) 7-6 (7-5) in London.
The Serb led 4-0 in the deciding tie-break but Thiem, trusting in his big-hitting, was able to outmuscle Djokovic and claim a fine win at the O2 Arena.
Thiem will play Rafael Nadal or Daniil Medvedev in the final.
