Damián Rivera

New England Revolution

In November 2019, Rivera signed a homegrown contract with the Revolution. He made his professional debut with New England's USL League One affiliate on 7 August 2020 against Orlando City B. In October of that season, Rivera scored his first professional goal, netting in the 83rd minute of a 4–0 victory over the Richmond Kickers. He would finish his inaugural season with the club with two goals and an assist in 14 league appearances. On 30 April 2022, Rivera made his first MLS start, and subsequently scored his first MLS goal, in the Revolution's 2–0 win over Inter Miami CF. In the process he became only the third player in league history to score in the first minute of his first MLS start, and the first to do so since Real Salt Lake's Matias Mantilla on 29 August 2007.

On January 18, 2026, he made his first appearance for Guatemala in a friendly against Canada, although as it was classified as a B-level friendly, it did not count as an official senior cap.
