OAKLAND -- The A's and catcher George Kottaras have agreed on a one-year contract for the upcoming season, the club said Monday.

Kottaras, a 29-year-old left-handed hitter, was acquired from Milwaukee in July and hit .212 with six home runs and 19 RBI in 27 games.

Kottaras was one of four players on the A's roster eligible for arbitration. The others are Jerry Blevins, Brandon Moss and Seth Smith.
