He notched his sixth consecutive goal, sparking a 4‑3 comeback that will live forever in Union lore. Who could’ve imagined such drama?
Sullivan’s brilliance has propelled Philadelphia to an 11‑match unbeaten streak—nine wins, no losses, two draws—since the World Cup pause.
Elite company
Breaking records now feels routine for the teen, whose 1‑goal, 1‑assist night at Sporting KC lifted his season total to 19 MLS contributions (seven goals, twelve assists).
Teaming up with Bruno Damiani’s strike, Sullivan set a new MLS benchmark: 12 assists, the most ever by a teenager in a single season.
He also ties with Vancouver’s homegrown star Alphonso Davies for the second‑most teen contributions in league history, also 19, a feat last seen in 2018.
With the calendar still wide open, he eyes the summit; Diego Fagúndez’s 20‑contribution mark from 2013 feels within reach. In my view, Sullivan is already reshaping the league’s teenage record books.
USMNT on his radar
His latest standout display arrived just after the youngster earned his inaugural USMNT call‑up.
Soon he’ll join fellow Union homegrown Neil Pierre and Frankie Westfield for friendlies against Peru, Chile, Mexico and Canada in the expanded September‑October window.
That nod signals strong confidence from USMNT boss Mauricio Pochettino, who launches the new cycle with twelve MLS selections.
‘It’s definitely exciting to finally get the invite. I didn’t expect it,’ Sullivan told reporters earlier this week.
‘Every kid dreams of this, and getting it truly made my year,’ he added.
An instant classic
The win wasn’t easy for one of the league’s hottest squads; Philadelphia fell behind three goals in the first 16 minutes and struggled to contain Sporting’s record signing André Luiz, who netted twice.
Then the tide turned: a Damian finish at 64 minutes sparked three unanswered goals, with Sullivan and Milan Iloski adding theirs before the final whistle.
Zorhan Bassong’s own goal in the 73rd minute sealed the night, delivering a memorable victory for the Union.
