While the Oakland Athletics have not been producing consistent offense more or less up and down the lineup -- with the exceptions of Josh Reddick and, once in a while, Yoenis Cespedes -- the team is apparently prepared to shake things up just a third of the way through the season.

Jane Lee at MLBlogs Network reports that the A's have designated Kila Ka'aihue for assignment and will recall Brandon Moss from Triple-A Sacramento. Moss has 15 homers in the minors this season and was hitting .286. He's been told he'll be playing first base with the A's, which effectively gives him Ka'aihue's roster spot. Grant Brisbee of Baseball Nation has more on the DFA move.

The A's also placed Andrew Carignan on the 15-day disabled list with s sprained ulnar collateral ligament in his right elbow. The A's called up right-handed reliever Evan Scribner in an accompanying roster move.
