Joe Mather, a right-handed 28-year-old corner outfielder and infielder, has been claimed by the Braves. Mather has shown decent on base skills in the minors and could be a useful player. MinorLeagueSplits.com is currently down, so researching his numbers against left-handed pitching is near impossible until the site is up.
Regardless, Mather has played a good amount in right field and in the corner infield spots. He could be a right-handed version of what Eric Hinske provided this season, which is something this team needs with left field and first base currently being occupied by left-handed hitters. He played more right field than anything else the past few seasons, but I am sure the Braves would look for him to be more flexible if they want him on the Major League team.
Mather posted a .348 on base percentage in triple-A last season, spanning 376 plate appearances. This could end up as a minor league depth move, or Mather could be a right-handed bench player in the case that Matt Diaz is not tendered a contract.
