Naturally a libero, though Castelli uses him at right back for San Lorenzo. Tall, strong, and quick to cover space vacated by teammates; carries the ball out of defense with real composure, and is a decent header of the ball. Specifically at right back he offers almost nothing going forward — a purely defensive role there.
An unconventional route into the club — at 16, living near San Lorenzo's training complex, he tagged along with a friend's son who had a trial lined up; when that boy backed out at the last minute, Tuzzio was asked if he wanted to try instead, and said yes without hesitating. He was one of six kept on from around 120 hopefuls that day. Started in the sixth division, worked up to the fifth, then spent a year mixed in with the reserves. Manager Veira later put him on the bench for a match against River, where he made his senior debut on 11 December 1993, a 1-1 draw — he hadn't even trained with the first team before that, and came on for Néstor Lorenzo with seven minutes left. Became a starter in Apertura '94, playing 17 matches mostly at right back, then 2 more in the 1995 Clausura title win over Rosario Central on the final matchday. Loaned out to Quilmes after that, where he was a regular starter as libero and was voted the tournament's best player in that position. In the last campaign chances were scarce until Castelli gave him a run at right back late on, which he took well — 5 matches, 1 goal, in Clausura '97. Has five younger siblings: Laura, Alejandra, Marcelo, Claudio and Daniel.
