“These are rivalry games. These are derby games. Things like this happen across the world and in no way am I embarrassed,” B.J. Callaghan said after his first game as U.S. interim coach. “It comes from a good place. They care about each other so much in that locker room that they’re standing up for each other. Sometimes does it have an issue where we take a red card? Yeah, but when you know where it comes from, you can accept it and it’s a learning lesson for us.”

Play was halted in the 90th minute because of homophobic chants. When action resumed, 12 minutes of stoppage time were signaled but resumed chants caused Barton to end the match in the eighth minute added minute.

“In terms of the chant, I want to make it very clear first and foremost, for our beliefs and our culture, it has no place in the game,” Callaghan said. “It has no place in our value system.”

McKennie and Dest are suspended for thes final. Luca de la Torre and Joe Scally are possible replacements.

“It’s definitely a blow,” Tim Weah said. “It comes with the game. I know the red cards are definitely a bummer, but it happens. Aggressive match tonight.”

With its first three-goal victory over Mexico in 23 years, the U.S. stretched its unbeaten streak against El Tri to six (three wins, three draws), matching the Americans’ longest, from 2011-15.

The U.S. went ahead when Gio Reyna poked the ball off Montes and then while prone, poked it forward off Jorge Sánchez. Pulisic burst behind the defenders, took a pair of touches and from the edge of the 6-yard box slotted the ball past goalkeeper Guillermo Ochoa.

McKennie started the move toward the second goal with a long pass down a flank to Weah, who crossed. A sprinting Pulisic got behind Israel Reyes and Sánchez, stabbing the ball in with his left foot from 6 yards,

Montes was given a straight red card in the 69th for kicking Balogun while the two were challenging. McKennie was given a red card two minutes later for placing a hand on Sánchez’s neck during the ensuing arguing and shoving.

Pepi scored his seventh international goal, receiving a pass from Dest, taking a touch and rounding Ochoa. Dest and Arteaga were sent off in the 86th for shoving each other.

“There was moments on both teams that we could have handled better.” Callaghan said.
