Cavan Sullivan’s record as the the youngest person to debut in a major North American pro sports league lasted less then two weeks.

On Sunday night,Thomas Caldwell McKenna "Mak" Whitham made her debut for NJ/NY Gotham FC at 14 years, one day.

Whitham came on in the 80th minute against the Washington Spirit in a NWSL x Liga MX Femenil Summer Cup match, which Gotham won 1-0.

The forward is nearly a full year younger than Sullivan, who was 14 years and 293 days when he came on for the Philadelphia Union earlier this month.

On Friday, Gotham announced it had signed Whitham to a pro contract, effective Jan. 1. It also signed the U.S. youth international to a national team replacement contract, which allowed her to be eligible for Sunday’s Summer Cup match.

Whitham has been training with Gotham throughout 2024 after joining the club’s preseason as a non-roster invitee. At 13, the forward scored the winning goal for Gotham against Deportivo Cali in a preseason match in Colombia.

In February, Whitham made headlines by signing a name, image and likeness (NIL) deal with Nike, becoming the youngest athlete in any sport to sign an NIL deal with Nike.
