The Nottingham Forest netminder was finally given a chance to start. Horvath only faced one shot on target and was caught out of position and flat-footed, watching the ball fly in at the near post from a tight angle.
Typically energetic on both sides of the ball, the Fulham left back popped up with a couple of emphatic clearances, but didn't have his usual impact in the final third.
The New York Red Bulls defender wasn't tested consistently, but made a couple of important interceptions to snuff out attacks before they became truly dangerous.
The Celtic man had a good last-ditch clearance and showed some slight improvement in the air, but like Long, he wasn't tested frequently.
Could Cannon have done a better job closing down Alexander Larin on the goal? Perhaps, but it's hard to put too much of the blame on the Boavista defender's shoulders. He improved going forward as the game went on, but didn't have a significant impact.
The new Leeds United signing was given the first half and displayed his typical energy, but didn't stand out in a disjointed 45-minute performance.
Tyler Adams had a quiet night by his standards. He's never afraid to put in a tackle, but too often he hesitated to play an entry ball into the box, opting for the safe option to maintain possession. As the match went on, he needed to be more aggressive.
Musah was the standout for the USMNT on the night. He was a menace on the ball, driving through the El Salvador defense on countless occasions. He forced Mario Gonzalez into a couple of saves, put a well-struck free-kick on target, and drew a red card with an exceptional run and give-and-go pass. A strong showing for the young Valencia midfielder.
Wearing the captain's armband for the 10th time, the Chelsea winger took a beating all night. He was fouled almost constantly, but still managed to create several of the United States' best looks, and grew more dangerous as the match went on.
The in-form Antalyaspor striker was isolated all night. He struggled to get on the ball, and couldn't hit the target on his best look of the match. In his defense, he didn't have much service to work with.
The Lille winger had a couple of bright moments in his 61-minute shift, but he couldn't turn potential into production. Unfortunately for him, the match really opened up after he was taken off.
Berhalter's game plan was clearly hampered by the dilapidated pitch, and the first 60 minutes of the match were a real struggle. In the last 30 minutes, and especially once both sides went down to 10 men, his squad was able to create more and more. It wasn't pretty, but it was a resilient point.
Brought on at halftime, the Juventus midfielder changed the match. He opened up El Salvador's defense with dynamic passing and his trademark late runs into the box were a constant threat.
Another halftime introduction, Ferreira's movement was crisp and he connected much more frequently with the midfield, opening up space in and around the box for his teammates.
The Heracles midfielder was brought in for the final 10 minutes and helped the US sustain pressure on El Salvador's goal. De la Torre set up the equalizer with an excellent ball into the box.
