At just 15 years old, Cavan Sullivan is already making waves in American soccer, and his recent standout performance for the Philadelphia Union has only solidified his reputation as one of the brightest young talents in the game. The teenage prodigy earned his first senior start on Wednesday evening during the 2025 Lamar Hunt U.S. Open Cup, where the Union triumphed over USL Championship side Indy Eleven in a nail-biting 5-4 penalty shootout after a 1-1 draw in regulation and extra time.
A Historic Start in the U.S. Open Cup
Sullivan’s performance in the high-stakes match was a testament to his maturity and composure, especially considering the pressure of playing in such a prestigious tournament at such a young age. His debut in a senior starting role was closely watched by fans and analysts alike, and the teenager did not disappoint. Over 120 minutes of play, Sullivan demonstrated his technical ability and work ethic, completing 30 of 40 passes, taking six shots, three of which were on target, and contributing defensively with two tackles and five ball recoveries.
Despite his tender age, Sullivan showed no signs of being overwhelmed by the occasion. His 59 touches on the ball included four in the opposition’s penalty box, underscoring his confidence in offensive situations. His ability to make things happen in the final third was particularly notable, even though he didn’t register a goal or assist on the night.
Key Stats from a Stellar Debut
Sullivan’s numbers from the match reflect his potential and versatility. Here are some key stats from his senior debut:
