Eight months and two coaches after Mexico crashed out of an embarrassing World Cup, most of the same players triumphantly raised the CONCACAF Gold Cup amid confetti and raucous cheers Sunday night. El Tri has reversed its fortunes with stunning speed, and its winning goal at SoFi Stadium came on an end-to-end play that was every bit as dramatic. Late substitute Santiago Giménez scored after an electrifying sprint in the 88th minute, and Mexico won the Gold Cup for the record ninth time with a 1-0 victory over Panama.
