MARK PRIOR, SP, CUBS, 2003
Prior can blame it all on Bartman. The former second overall pick of the 2001 draft had a nice rookie season in ’02, but then excelled the following year by striking out 245 batters, notching an 18-6 record with just a 2.43 ERA, which put him third in the voting for the Cy Young Award. But in Game 6 of the NLCS, Prior was on the mound with a three-run lead against Florida when Steve Bartman took away the foul ball from Moises Alou. The Marlins then scored eight runs in the inning and the Cubs ended up losing the series. Prior spent parts of the next three seasons on the disabled list, and never pitched again in the majors after that.
