The biggest game of the group stage of the 2017 CONCACAF Men's U-17 Championship was unquestionably Mexico vs USA - the match-up featuring the two teams expected to make the final of the tournament. El Tri carried a 25-game unbeaten streak in CONCACAF U-17 Championships into the game, and the USA had never beaten Mexico in this tournament. That changed on April 26, 2017: the USA pulled out a 4-3 win that wasn't quite as close as the final score suggests.
Mexico opened the scoring in the sixth minute and finished it in injury time, and the game was tied, 2-2, at half-time.
