The Rockies went into the 2018 season with McMahon as the primary first baseman, but after 28 games he was sent down to the Isotopes after beginning the season with just three RBIs and hitting .180 in 50 at-bats. On June 14, 2018, McMahon hit his first major league home run. On August 11, with the Rockies trailing 0–2 to the Los Angeles Dodgers in the bottom of the 9th inning, McMahon hit a two-out three-run walk-off home run off Dodgers closer J. T. Chargois to give his team a 3–2 victory. It was McMahon's first career walk-off homer and came only a day after he had hit another go-ahead home run against the Dodgers that proved to be the game winner.
