Regular season

Summary The 2003 season was a surprise to both team management and baseball analysts. After a poor April, the team had its most successful month ever in May. The offense was mainly responsible for the stunning turnaround. Delgado took over the major league lead in runs batted in, followed closely by Wells. The middle infield positions remained a gametime decision – Bordick played shortstop and third base, Dave Berg second base and third base, Chris Woodward shortstop and Orlando Hudson second base. Minor league call-up Howie Clark entered the mix as a utility player after Hinske underwent surgery to repair a broken hamate bone in his right hand, which he had tried to play through for the first six weeks.

Despite their hitting successes, poor pitching continued to plague the team. Roy Halladay was spectacular in winning his first Cy Young Award, going 22–7, with a 3.25 ERA, but he didn't get much help from his fellow pitchers, although he had a poor start himself. Rookie Aquilino López was a pleasant surprise out of the bullpen. Kelvim Escobar and former NBA player Mark Hendrickson were inserted into the rotation with their places in the bullpen filled by waiver acquisitions Doug Davis and Josh Towers, who went 8–1 after being called up from Triple-A Syracuse. The closer role was a season-long revolving door, with nobody able to take hold of the reins. Trade speculation had focussed on the acquisitions of pitching at the expense of hitters, but in the end the team simply divested itself of impending free agent Shannon Stewart without getting a pitcher in return. Instead Bobby Kielty, another outfielder with a much lower batting average than Stewart's, was obtained from the Minnesota Twins and later traded in November 2003 to the Oakland Athletics for starter Ted Lilly. The top four pitchers for the projected 2004 rotation would include Halladay, Lilly, free agent Miguel Batista, and the return of Pat Hentgen.

After the spectacular turnaround in May 2003, which helped the team move to just few games behind the wildcard leading Boston Red Sox, team performance slowly returned to reality, as predicted by team management. Carlos Delgado was second in the voting for the American League MVP Award, although the Jays were in third place in their division. The Jays also announced that a new logo, and new uniforms, would be used as of January 1, 2004.
