The A’s have acquired first baseman Ike Davis from the Pirates for international bonus slot money, tweets Susan Slusser of the San Francisco Chronicle. The A’s and Pirates have both tweeted confirmation of the trade, which also includes a swap of international bonus slots: the Pirates receiving the A’s first slot ($501.9K) in exchange for their third slot ($232K). The Pirates will net $269.9K in the swap of bonus slots (figures courtesy of Baseball America’s Ben Badler). To create room on the 40-man roster, the A’s have designated outfielder Andrew Brown for assignment.

Slusser tweets acquiring Davis, who was designated for assignment by the Pirates on Thursday, is a depth move and not an indication the A’s are preparing to deal any of their first basemen. The trade comes less than a week after Oakland signed Billy Butler to a three-year, $30MM free agent contract. The 40-man roster logjam at DH/first base now include the aforementioned Davis and Butler plus Brandon Moss, John Jaso, Stephen Vogt, Kyle Blanks, and Nate Freiman. With this surplus, Slusser notes the A’s now have the flexibility to make a deal if they are overwhelmed by an offer.

Davis struggled to start 2014 with just five hits, including one home run, in 30 plate appearances before being dealt by the Mets to the Pirates in April. The 27-year-old fared slightly better in Pittsburgh slashing .235/.343/.378 with ten home runs in 397 plate appearances. Davis is projected by MLBTR contributor Matt Swartz to earn $4.4MM in his second time through arbitration.

The A’s claimed Brown off waivers from the Mets on Halloween. The 30-year-old produced a .182/.245/.341 slash with the Mets in 49 plate appearances. Brown has spent parts of four MLB seasons with the Mets, Rockies and Cardinals compiling a batting line of .220/.281/.390 in 362 trips to the plate.
