MASON, Ohio (AP) Novak Djokovic has reached the finals of the Western & Southern Open for the second straight year.

He got the best of Juan Martin del Potro in their bronze medal rematch, winning 6-3, 6-2 on Saturday afternoon. Del Potro beat Djokovic for Olympic bronze on Wimbledon's grass two weeks ago.

The Serb will face the winner of the other semifinal between top-ranked Roger Federer and Swiss countryman Stanislas Wawrinka. Last year, Djokovic reached the Cincinnati finals but had to quit because of a sore shoulder, giving the title to Andy Murray.

It's been a good week for Djokovic, who won the Rogers Cup in Toronto last Sunday and managed to get some rest in Cincinnati. His match Thursday lasted only a half-hour because his opponent got hurt.
