O'Day filed for arbitration, asking for $1.4 million, while the club offered $1.05 million. O'Day was 6-2 with a 2.03 ERA in 72 appearances last season, but he struggled in the World Series and ALCS, giving up four runs in 2 2/3 innings in those two rounds of the playoffs.
Frank Francisco and Josh Hamilton are the team's remaining arbitration cases. Hamilton said earlier this week that his case is scheduled for Feb. 14.
