Stewart established a new record for most consecutive strikeouts in an MLB debut with seven in the Orioles' 9-3 victory over the Chicago White Sox in the second game of a twi-night doubleheader at Memorial Stadium on September 1, 1978. His performance surpassed the milestone established by Karl Spooner in 1954. Stewart appeared in one game of the 1979 World Series. In innings, he gave up four hits but did not surrender a run.

He earned an ALCS save on October 7. He had been placed on 18 months probation the day before, stemming from a July arrest for driving while intoxicated. His attorney announced that Stewart was undergoing treatment for alcohol problems. Stewart was traded to the Boston Red Sox in exchange for Jackie Gutiérrez after the 1985 season. In February 1986, newspapers reported that the Orioles wanted to nullify the trade because of the emotional state of Gutierrez. Stewart said that he had already settled in Boston and that he would fight any attempts to return him to Baltimore. Years after his retirement, Stewart blamed Boston's 1986 World Series loss on the team's manager, John McNamara. He said that he had not been on good terms with McNamara since he narrowly missed a team bus after visiting his son in the hospital. A confrontation ensued between Stewart and the team's traveling secretary. Stewart said that McNamara held a grudge from the incident which led to Stewart not appearing in the World Series. He pitched in 359 major league games, finishing with a 59–48 record, 45 saves, and a 3.59 earned run average.
