outrighted from the 40-man roster and assigned to Scranton/Wilkes Barre on April 8. Romine batted .260 with seven home runs for the RailRiders in 2015. The Yankees promoted Romine to the major leagues on September 1. During spring training in 2016, Romine won the backup catcher competition over top catching prospect Gary Sánchez. In 2016 as the Yankees' backup catcher, Romine played in 62 games hitting .242 with 4 home runs and 26 RBI. In 2017, Romine began the season as the backup to Gary Sanchez, but after an injury to Sanchez on April 8, Romine became the Yankees starting catcher until Sanchez returned at the start of May. On August 24, Romine got into an altercation with Miguel Cabrera at home plate. Cabrera shoved Romine, triggering a bench-clearing brawl, and both combatants were ejected. The next day, on August 25, Romine was suspended for two games, pending an appeal. On September 8, Romine dropped his appeal, and began serving his suspension, which was reduced to one game. He batted .218 for the season. He had the lowest batting average against left-handers among all MLB hitters (60 or more plate appearances), at .143. Romine became the primary catcher for the Yankees after Gary Sánchez was injured in June 2018, and again re-injured in July. He was expected to serve in this role until Sánchez's return. On July 24, Romine was announced as the Yankees' "Heart and Hustle" award winner. On October 8, Romine pitched in the top of the ninth inning in a 16–1 loss to the Boston Red Sox in Game 3 of the 2018 American League Division Series, becoming only the second position player to ever pitch in the postseason, the first since Toronto Blue Jays infielder Cliff Pennington in the 2015 American League Championship Series against the Kansas City Royals. Romine allowed two runs in the inning by allowing a two-run home run to Brock Holt which made Holt become the first player to hit for the cycle in an MLB postseason game. On April 21, Romine hit his first career walk-off hit, an RBI single in a 7-6 win over the Kansas City Royals. On July 25, Romine made his first career pitching appearance in the regular season, pitching in the bottom of the eighth inning in a 19-3 loss to the Boston Red Sox, who he pitched against in Game 3 of the 2018 ALDS.
