Djokovic sets up Nadal showdown at Tour Finals
LONDON - Novak Djokovic set up an ATP Tour Finals showdown with Rafael Nadal as the defending champion booked his semi-final berth by taking the first set against Tomas Berdych on Thursday.
After Roger Federer's win over Kei Nishikori earlier in the day, world number one Djokovic knew he would advance to the last four if he could secure one set against Berdych in his concluding group match.
The Serb wasted little time achieving that goal as he won the first set 6-3 to ensure he would finish second in the group behind Federer.
Djokovic's bid to win the Tour Finals for a record fourth successive year will next be tested by Nadal, who looked in fine form while romping to wins over Stan Wawrinka and Andy Murray to secure top spot in the other group.
Federer will face either Wawrinka or Murray for a place in the final.
