The next trip for him is to Bogota, Columbia. The ATP gave him a SE and he plays Sebastian DECOUD (ARG.) The O.O.P. still has yet to be realeased for Monday, but I doubt they will make him play tomorrow. Still no word on whether or not he will play doubles.
Mariano will play his first round singles match against Sebastian DECOUD (ARG) on Tuesday; Court 1, Second match on after 10:30 a.m. In doubles Mariano will team with countrymen Mariano PUERTA (ARG) to take on Maximo GONZALEZ/Sergio ROITMAN (ARG/ARG)  on Wednesday.
Sebastian DECOUD (ARG) Defeated Mariano ZABALETA (ARG) 6-3, 6-4. No worries, I am sure he is very worn out. Also, it good to see that he got an extra game in the second set, he did not give up. He is still alive in doubles.
