Daric Barton will be the Athletics' regular first baseman against right-handed pitching. John Jaso's concussion issues appear to be behind him, clearing the way for him to see the bulk of his playing time behind the plate. That opens up the designated hitter spot for Brandon Moss and first base for Barton. The 28-year-old offers a nice eye at the plate and a good glove at first but sports just a .223/.334/.298 batting line over the last three seasons.
