MLS phenom Cavan Sullivan, 14, becomes youngest player to make North American professional sporting debut

Cavan Sullivan, at just 14 years old, didn't just make MLS history when he came on as a substitute for the Philadelphia Union on Wednesday night against the New England Revolution.

He made history in North American professional sports.

At 14 years and 293 days, Sullivan became the youngest player to make his debut in any major professional sports league in North America when he took the field to play for the Union's senior team on Tuesday.

This incredible feat, as the commentator said during the Apple TV broadcast, was not just about selling tickets. Sullivan has long been a footballing great, having signed the largest homegrown contract in MLS history on May 9.

As part of the deal, Sullivan will move to the English Premier League – one of the world's top leagues – Manchester City after he turns 18.

For MLS, Sullivan broke Freddy Adu's record by just a few days, when he made his debut for D.C. United against the San Jose Earthquakes on April 3, 2004, at 14 years, 306 days.

Adu, however, remains the youngest player to ever play for the U.S. men's national team at 16 years, 234 days. Some believe Sullivan has a chance to break that record as well.

The Union demolished the Revolution on Wednesday night, and although a Sullivan was on the goal sheet at the end, Cavan was not the first name.

His older brother Quinn is also a Union star and he scored in the 84th minute. The younger Sullivan didn't have many chances to score that first goal or assist in the game, although he did score a goal late in the second half.

Sullivan has spoken publicly in the past about the emphasis he placed on his individual journey when signing.

“I think it would be nice to have my first record, but it doesn’t really matter to me if I break it or not,” he said via ESPN. “I mean, everybody’s on their own path. It’s not really where you start, it’s where you finish.”

Sullivan added that signing with the Union was always where he wanted to start because it's his hometown team, and playing with his older brother is also an easy sell.

“I’ve always been inspired by playing in front of this culture, and these fans are special,” he said upon signing.

The addition of Manchester City to his contract sealed the deal for Sullivan, and now he begins this journey towards what many expect to be a fantastic football career.
