The A's have acquired outfielder/first baseman Kyle Blanks from the San Diego Padres and, in turn, designated first baseman Daric Barton for assignment. Blanks will join the A's in Cleveland on Friday as the team begins a nine-game road trip by facing the Indians.

The A's sent minor league outfielder Jake Goebbert and a player to be named later to acquire Blanks, a 6-foot-6, 265-pounder with power who has struggled to earn consistent playing time in San Diego.

Barton has never got it going this season with the A's, batting just. 158 with no home runs and five RBIs. At one point Barton was the A's full-time first baseman -- he played in 159 games in 2010 -- but he's never delivered the average or power expected from a corner infielder.

His best season was in 2010 when he hit .273. He led the American League with 110 walks and was fifth with a .393 on-base percentage. But his lack of power -- for his career he's averaging one home run every 58 at-bats -- and a career .247 batting average have been his downfall.
