Padres and RHP Luke Gregerson avoided arbitration by agreeing to a one-year contract. No word yet on the terms, but Gregerson was arbitration-eligible for the first time this winter. The 27-year-old right-hander posted a 2.75 ERA and 34/19 K/BB ratio over 55 2/3 innings last season. He'll set up for new closer Huston Street in 2012.
