The Los Angeles Dodgers made a few low-key acquisitions this past offseason following two years of high-profile roster building. Just two weeks into the new season, some of those players are already playing major roles for the Dodgers.

Dan Haren has been a pleasant surprise at the back of the rotation, and Chris Perez has made a seamless transition to a setup role.

Meanwhile, L.A.’s highest-profile offseason acquisition, Cuban infielder Alex Guerrero, hasn’t had any impact on the major league club. He was sent to Triple-A Albuquerque out of spring training to continue working on his transition from shortstop to second base.
