Daric Barton Candidate For Extension

There's another candidate for a multi-year extension who might beat Cahill to the punch, however: First baseman Daric Barton, who like Cahill would be arbitration-eligible after the season, is a strong possibility to be signed through at least 2014, according to a source. The A's value his ability to get on base, his defensive ability at first base and his durability; Barton, 25, played in 159 games last season.
