World number two Rafael Nadal stepped up his bid for a third ATP Mexico Open title with an impressive display of serving and shotmaking to beat Serbian youngster Miomir Kecmanovic on Wednesday.
The Spaniard hit 20 winners as he kept his hopes alive of regaining the top ranking with a 6-2, 7-5 victory over the 20-year-old Kecmanovic to reach the quarter-finals at the Acapulco hardcourt tournament.
"He's a very dangerous player. Young, with a lot of power. I'm very pleased with the victory," Nadal said.
"I played a very good first set and that's important for me. That gives me confidence."
Next up for Nadal is Kwon Soon-woo, who reached his fourth quarter-final of the month with a 7-6 (7/2), 6-0 upset against eighth-seeded Dusan Lajovic. South Korea's Kwon also reached the last eight in Pune, New York and Delray Beach.
Nadal improved to 17-2 overall at this event. He needs to take the Acapulco title and have Novak Djokovic lose his semi-final match at this week's Dubai Tennis Championships to regain top spot.
