In his first season with Baltimore, Jimenez was 6–9 with a 4.81 ERA in 25 games (22 starts). He was included on the team's ALDS roster, but did not pitch in the series. Despite being on the ALDS roster, Jimenez was left off of the O's ALCS roster against the Kansas City Royals. After this failed season the Orioles President Dan Duquette refused to cut him or trade him because the team believed he could bring back that half a season of success.
