Zeballos's title win was the very first ATP tour championship for the 27-year-old from Argentina despite turning professional in 2003. In 2012, Zeballos did not advance past the 2nd round of any tournament he entered on the ATP tour, but in Vina del Mar he beat four seeded players in succession to claim the title: #4 seed Pablo Andujar, #5 seed Albert Ramos, #8 seed Carlos Berlocq and #1 seed Nadal. The Argentinean won on his first match point at 4-5, 0-40 in the third set.
Nadal said that he felt some pain in his troublesome left knee earlier in the week. He teamed up with his good buddy Juan "Pico" Monaco to play the doubles and reached the final, losing to Potito Starace and Paolo Lorenzi of Italy 6-2 6-4.
Nadal will continue his comeback by playing another clay court tournament, in Sao Paulo, Brazil next week.
