Worth noting

• Infielder Hiro Nakajima, signed by the A's to a two-year, $6.5 million deal at the end of 2012, was transferred from Triple-A Sacramento to Double-A Midland on Wednesday.

The Japanese import hasn't panned out as the A's hoped. Initially pegged as their potential starting shortstop for 2013, Nakajima struggled last spring and began the season on the disabled list. He spent the entire year in Sacramento and, through 12 games with the River Cats this year, was batting just .128.

• Jed Lowrie got a scheduled day off Wednesday, as Eric Sogard got the start at shortstop next to second baseman Nick Punto.
