As a member of the Blue Jays rotation in 1993, Stewart made 26 starts and was 12–8 with a 4.44 ERA. He suffered from a number of injuries during the season but the Blue Jays stuck with him because of his heart and competitiveness as well as the support he offered to other pitchers on the staff. The Blue Jays made it to the ALCS where Stewart got the call in game two. He allowed only one run in six innings of work to pick up the win. The day before his next start, while the rest of his team was already in Chicago, he was in Toronto helping the Salvation Army deliver food to the homeless on Thanksgiving Day in Canada. He made it to the game on time, and pitched 7.1 innings for his second win of the series, in the clinching game six that sent the Blue Jays back to the World Series. He was selected as ALCS MVP for the second time in his career. In the 1993 World Series against the Philadelphia Phillies, Stewart got the start in game two and struggled, allowing five runs in six innings to take a rare post-season loss. Nevertheless, he was confident heading into his next start, in game six, saying he was pitching for respect as much as for another championship. He allowed four runs in six innings but that was enough as the Blue Jays, thanks to a three-run walk-off homer by Joe Carter won the game 8–6 and with it took the series, 4 games to 2.
