2020–2023
During the start-delayed 2020 MLB season, Houck won his MLB debut against the Miami Marlins on September 15, allowing two hits and no runs in five innings pitched while striking out seven batters. Those strikeouts resulted in Houck donating $700 to his charity, Pitch for Adoption, as before the game he had pledged to donate $100 for each strikeout. While Houck was a freshman in high school, his family adopted a 4-year-old girl, which moved him to become a supporter for adoption. Houck became only the fourth player in Red Sox history to strike out seven or more batters and not allow any runs in an MLB debut game. In Houck's second start, against the New York Yankees on September 20, he took a no hitter into the sixth inning, exiting the game after that inning having held the Yankees to one hit and one unearned run. Overall with the 2020 Red Sox, Houck appeared in three games, compiling a 3–0 record with 0.53 ERA and 21 strikeouts in 17 innings pitched.
