Jesus Duenas and Armando Pulido scored to give UANL Tigres of Monterrey a 2-1 victory over 10-man Chivas USA in group play at the SuperLiga tournament Saturday night.

Tigres won with its under-20 team, which played in Mexico's second division last season, to tie the Chicago Fire for first place in Group A. Each team has three points.

Duenas broke a 1-1 tie in the 82nd minute. Chivas USA goalkeeper Zach Thornton dived to stop Alan Pulido's 11-yard shot with his left hand, but Duenas converted the rebound from six yards.

Chivas USA had to play with 10 men after Eduardo Lillingston received his second yellow card in the 67th minute. Lillingston is suspended for Tuesday night's SuperLiga game against Chicago.

The top MLS teams from last year's regular season who weren't in the CONCACAF Champions League were invited to the SuperLiga along with the top four Mexican clubs who weren't in the region's top club tournament.
