With the signing of veteran starter Esteban Loaiza before the season, the A's bumped Saarloos to the bullpen. Soon after, Rich Harden got injured, and Saarloos was put in as a fifth starter for a few games. He was also used in many varying relief roles, much like Justin Duchscherer was in 2005, but also as a spot starter. Shifting between the bullpen and the rotation, Saarloos finished with a record of 7-7 in 35 games for the A's. He allowed more home runs (19) than the previous season (11). On January 19, , Saarloos signed a one-year $1.2 million deal with the Athletics.
