Who is Cavan Sullivan? Philadelphia Union’s 14-year-old breaks Freddy Adu’s MLS age record

History has been made in Chester, Pa. as 14-year-old Cavan Sullivan became the youngest player to ever appear in a Major League Soccer game at 14 years, 293 days old. Sullivan broke a 20-year-old record that was held by Freddy Adu who accomplished the feat for D.C. United on April 3, 2004 against the San Jose Earthquakes at 14 years, 306 days old.

It was a poetic moment as he entered in the 84th minute after his older brother Quinn Sullivan scored a beautiful goal from outside the box. Sullivan came on to cheers in Subaru Park, breaking Adu’s record by 13 days to help the Union close out their match against the New England Revolution.

Here’s what to know:

Who is Cavan Sullivan?

Cavan signed a record-breaking homegrown player deal where he’ll earn more than $500,000 per season. After signing that deal, Sullivan has been playing for the Union’s MLS Next Pro team where he has performed well. Sullivan is also expected to join Manchester City when he turns 18.

Following in the footsteps of his older brother, Sullivan is quickly making a name for himself while also playing in midfield. That homegrown deal helped pave the way for Sullivan to debut, but it’s been tricky as the Union have also had to manage child labor laws to ensure that his debut happens at the right time. When the Union faced Toronto FC over the weekend, Sullivan wasn’t able to play due to Canadian laws paving the way for his debut at home in Chester.

What is a homegrown deal?

A homegrown player is similar to an academy deal in England. Each MLS team has territories that they’re allowed to scout in and sign players from after they’ve completed 12 continuous months with the team’s academy. That period must conclude between when a player turns 14 until they turn 18. By doing that, the players will get a homegown tag when signed allowing them to not count against the salary cap for a period and allowing teams to retain more money if they are transferred to another team. The rules are in place to promote local development among teams.

There are at times disputes due to overlapping territories and how much time was continuously spent with a team’s academy but those are decided by the league. 

What’s next for Sullivan?

While Sullivan’s debut is quite a moment in his career and a record-breaking moment for the Union, this is also where the cautionary nature of Adu’s career comes into play. Adu reflected on his career on CBS Sports Golazo’s Morning Footy recently.

“Sometimes, you have all the talent in the world and it’s not enough. You’ve got to work your butt off to maximize that talent and guys who aren’t as talented as you, if they work their asses off, they’re going to surpass you,” Adu said. “And it happened in my case. There were a few guys that obviously weren’t as talented, but they put in the work and they had more success.”

With players like Sullivan and Barcelona‘s Lamine Yamal, it’s important to manage them while setting them up for success. As a team that has seen homegrown players like Mark McKenzie, Brenden Aaronson, and Paxten Aaronson make the jump to the next level, the Union are aware of this but with a player so young, it can be hard to keep pressure off of them while things are changing so quickly. 

As Sullivan can’t join Manchester City until he turns 18, much of his formative years will be spent with the Union. Sullivan has the potential to be one of the brightest talents to emerge from U.S. soccer but it’s a talent that needs to be nurtured and protected.
