In the late CONCACAF Champions League game Tuesday night, Enner Valencia and Luis Quinones each had a goal and an assist in the second half at Houston as Mexican side .
In the 78th minute, Valencia chipped a pass over a defender's head to Quinones, who immediately returned the ball to Valencia on a give-and-go that resulted in a 7-yard goal.
Three minutes later, Valencia's long diagonal pass for Quinones just outside the box resulted in a perfect first touch by Quinones, allowing him to get wide of the lone defender and hammer home an 18-yard shot.
The second leg will be played March 12 at San Nicolas de los Garza, Mexico.
