The A's have agreed to terms on one-year contracts with first baseman Brandon Moss and left-handed reliever Jerry Blevins on Friday, and now have all their arbitration eligible players in the fold. Moss, 29, joined the A's in June and hit .291 with 21 home runs and 52 RBI in 84 games. Until coming to Oakland, the left-handed hitter had spent parts of five seasons with the Boston Red Sox, Pittsburgh Pirates and Philadelphia Phillies. Originally drafted by the Red Sox, he had managed just 15 homers and 78 RBI in 249 games before playing for the A's.
