* HOUSTON (AP) --*Aaron Padilla scored the go-ahead goal midway through the second half to help Club America of Mexico City defeat Portmore United of Jamaica 2-1 in the quarterfinals of Series 1 play in the CONCACAF Champions Cup on Wednesday night.
Padilla scored on an easy kick from the left in the 73rd minute. Miguel Zepeda got the assist from the middle as he drew the goalkeeper out of position for Padilla's kick.
The teams were scoreless in the first half although Club America appeared to score in the 8th minute on a kick by Francisco Torres that hit the crossbar and bounced straight down.
Both teams continued playing while the stadium announcer went into his long "G-O-O-A-L" yell, and the heavily pro-Mexican crowd went wild and scorekeepers put up a goal on the scoreboard before it was realized it didn't count.
Portmore had only two saves and Club America one in the first half as there was little activity around either goal.
The shutout ended quickly in the second half as Portmore's Remeel Wolfe took a crossing pass from Omar Daley and headed the ball in the goal in the 52nd minute.
Club America tied it up in the 60th minute after Portmore's Demar Stewart was charged with a foul against Zepeda in front of the goal. Christian Gimenez scored on the penalty kick.
The two teams play again March 8 in Aztec Stadium at Mexico City. The winner of the series will advance to the semifinals March 21-23 with the finals scheduled April 11-13.
