If you're good enough, you're old enough. And MLS has plenty of talent for which that aphorism rings true.
Following the New York Red Bulls' signing of midfielder Bento Estrela to a Homegrown contract on the day before his 15th birthday, there's a new entrant in the league's 10 youngest signings.
Estrela becomes the fourth youngest player to sign for an MLS team, and the youngest player signed since 2019. Teenage talent continues to burgeon in MLS, though still atop the list is former wunderkind Freddy Adu, who signed his first contract when he was just 14 years and 168 days old in 2004.
