Novak Djokovic, Juan Monaco win

Top-ranked Novak Djokovic advanced to the Sony Ericsson Open semifinals, beating No. 5 David Ferrer 6-2, 7-6 (1). Djokovic lost a remarkable 40-shot rally that had spectators gasping as it progressed, but he played a nearly flawless tiebreaker to seal the victory.

"Coming into this tournament, I was confident," Djokovic said. "And I feel that I am playing better and better as the tournament goes on."

Djokovic seeks his third Key Biscayne title and second in a row. His opponent Friday night will be No. 21 Juan Monaco, who advanced on his 28th birthday by eliminating the last American in either singles draw, No. 8 Mardy Fish. The scrappy Monaco dominated from the baseline and hit only eight second serves during the 6-1, 6-3 victory.

"This is the way to celebrate my birthday, playing like this," Monaco said. "I feel proud and very happy."

No. 2 Rafael Nadal, seeking his first Key Biscayne title, plays 2009 champion Andy Murray in the other semifinal.
