After the World Series, Torrez signed a seven-year, $2.5 million contract with the rival Boston Red Sox and helped them contend for the American League (AL) East title all season. Boston and New York finished the season with identical records, and Torrez pitched the tie-breaker game to determine the winner. He allowed a pivotal home run to Bucky Dent of the Yankees, and though he was initially cheered by Red Sox fans as he left the game, he would soon become a scapegoat for a frustrated fan base. He pitched for Boston for four more seasons, winning 16 games in 1979 and finishing second in the AL in winning percentage in 1981. After the 1982 season, he was traded to the Mets, with whom he served as a mentor for New York's young pitchers. He was released in 1984 and pitched two games with Oakland that year before finishing his career in the minor leagues in 1985.
