The USA, which had beaten Mexico, 4-3, in first-round group play, took the lead in the final in the 62nd minute when Andrew Carleton hit a volley on the turn from 18 yards that bounced past Cesar Lopez at the far post.
The Americans had two good chances to extend their lead. Lopez blocked a close-range Josh Sargent shot from a tight angle in the 81st minute and Chris Goslin hit the post from 18 yards in the 90th minute.
Halfway into the four minutes of stoppage time added by referee Hector Martinez, Daniel Lopez chipped in a cross that Carlos Robles headed low into the right corner of the U.S. goal.
With overtime not used at this competition, the teams headed straight into the shootout. Every player converted except the USA’s fourth shooter, Akil Watts, an 86th-minute sub, who shot high.
”It stings,” said Hackworth. “There’s no way to take that kind of result … That said, I’m proud of these young men. I’m proud of my staff. I’m proud of the way we performed in the tournament. So we need to walk out of here with our heads held high and understand that we have some more work to do in order to win championships in the future."
The win gave Mexico’s its third straight U-17 Concacaf title and a record seventh overall.
