DUBAI, United Arab Emirates (AP) -- Novak Djokovic has reached the final of the Dubai Championships, defeating fourth-seeded Juan Martin del Potro 6-3, 7-6 (4) on Friday.
The top-ranked Serb, bidding for his fourth Dubai title in five years, made the only break of the first set and came from 3-0 down in the second.
Serving at 3-1, 30-40, the Argentine was given a time violation. A furious del Potro then hit a forehand wide to make it 3-2. Djokovic broke again to make it 4-3 only for del Potro to even the set at 5-all.
Djokovic then forced the tiebreaker.
