Belgrade, Serbia (Sports Network) - Novak Djokovic fought off a challenge from Feliciano Lopez to win Sunday's final at the Serbia Open and stay perfect in 2011.
The top-seeded Djokovic recorded a 7-6 (7-4), 6-2 victory in about two hours. Lopez fired six aces in the first set, when the players combined to save 8- of-8 break points.
But Djokovic pulled out the tiebreak, then used a strong serve to win the second set and his fifth title of the season.
The Serb improved to 27-0 this year, the best start to begin a season since Ivan Lendl won his first 29 matches in 1986.
He also won his hometown tournament for the second time (also 2009), and earned $96,800 for the victory.
"Today I was playing for the title in front of so many people," Djokovic said. "It's always a huge motivation for me, but also a huge responsibility with the kind of expectations that I feel. I was aware of that and that's why I was maybe a little bit more nervous."
The Spanish Lopez fell to 2-5 all-time in ATP finals, and to 0-4 lifetime against Djokovic. He last won a tournament in February 2010 at Johannesburg.
