Argentinean David Nalbandian has booked a place in quarterfinal of Copa Telmex 2010 championship due in Buenos Aires.

David Nalbandian, visibly struggling with a right leg injury, fought his way to a 6-7, 6-4, 7-6 win over Daniel Gimeno-Traver Wednesday evening. The former Copa Telmex champion missed three match point opportunities before securing the victory in two hours and 47 minutes.

After splitting the first two sets, Nalbandian held an early edge in the third. The Argentine led 2-0, aided by two consecutive doubles from the Spaniard. Nalbandian reached 5-3, but turned in an errant backhand on break point to drop serve. A second-set tie-break contained several shifts in momentum, as the Argentine gave away critical points at 3-1 and 6-5. Nalbandian regrouped to collect his fourth match point at 8-7, ending the evening with a heavy forehand.

He moves on to face fifth seed Albert Montanes in the quarterfinal. The Spaniard recorded a 6-3, 6-2, 67-minute win over qualifier Pablo Andujar in the round of 16, tennistalk.com reported.
