International career
Underwood is of Puerto Rican descent through his maternal grandmother. During the 2023 World Baseball Classic (WBC), he pitched for the Puerto Rico national team. On March 13, 2023, he pitched in relief versus Israel and retired every batter faced in the eighth inning, after José De León started and Yacksel Ríos, Edwin Díaz kept the perfect game intact, and Martín Maldonado caught on the way to a 10–0 win. The contest ended when Maldonado scored on a walk-off hit in the bottom of the eighth inning that invoked the tournament's mercy rule. However, it did not qualify as an official perfect game per the Elias Sports Bureau, due to lasting fewer than nine innings.
