April 2004: Freddy Adu makes his MLS debut against San Jose

Dubbed The New Pelé Freddy Adu was a promising 14 years and 306 days old when DC United head coach Piotr Nowak decided to hand him his debut in the opening game of the 2004 MLS regular season against the San Jose Earthquakes at RFK Stadium. In front of 24,603 fans and wearing the No.9 jersey, the teenage attacking midfielder replaced goal scorer Alecko Eskandarian on 61 minutes with United leading 2-1.

Both teams were reduced to 10 men while Freddy was on the pitch and he saw little of the ball during his 29-minute cameo but at least he ended on the winning side and took the record for being the youngest player to star in MLS and the youngest sports professional to debut in the US.

Freddy Adu still the youngest goal scorer in MLS history

It was the first of 30 appearances that Freddy would make that season – his first goal came in his third game, in the 3-2 defeat to the New York Metrostars. Despite being surpassed by Cavan Sullivan on Wednesday night, Freddy Adu still has the honor of being the youngest player to score in MLS, at 14 years and 320 days of age. The closest anyone has got to that record was Julian Hall who scored a late equalizer for the New York Red Bulls in the 2-2 draw at Montreal last month. At 16 years and 87 days, Hall is the MLS’ second youngest goal scorer.

While Maximo Carrizo is officially the youngest player in MLS history having signed a professional contract with New York City FC on his 14th birthday and Real Salt Lake signed Axel Kei when he was barely a fortnight older than Carrizo, aged 14 years and 15 days, neither has made their top flight debut.
