Seattle successfully bunkered down in front of a full stadium in Léon, ceding possession but defending valiantly to earn the 1-1 draw. Club Léon had 26 shots, with eight on target, but managed to score only a single goal in stoppage time. After going up 3-0 in the first leg, Seattle made a plan and stuck to it: Park the bus, try to sneak in an away goal.
The Sounders succeeded where the New England Revolution failed. Last night, the Revs took a 3-0 lead over Pumas UNAM to the second leg in Mexico City, then promptly shipped three goals. The tie ended in a draw, and Pumas won the ensuing penalty shootout.
CF Montréal and Cruz Azul also played last night in Montréal, with Cruz Azul advancing on 2-1 aggregate.
On Tuesday, NYCFC tried to defend their 3-1 first-leg lead over Comunicaciones FC like Seattle, and almost imploded like New England. After going up 1-0 in Guatemala City, NYCFC lost the game 2-4 but advanced to the Semifinals on away goals.
