Susan Slusser reports that the A’s season of dealmaking will continue, this time by acquiring Ben Zobrist and Yunel Escobar from the Rays:

The #Athletics are on the verge of acquiring Ben Zobrist and Yunel Escobar from the #Rays, the @sfchronicle has learned. — Susan Slusser (@susanslusser) January 10, 2015

Update:

SS Daniel Robertson is indeed in the Zobrist deal, I can confirm, and I can report that OF Boog Powell also goes to #Rays. #Athletics — Susan Slusser (@susanslusser) January 10, 2015

And John Jaso:

So it is Zobrist/Escobar to #Athletics for Jaso, SS prospect Daniel Robertson (reported by @Ken_Rosenthal), OF prospect Boog Powell #Rays — Joel Sherman (@Joelsherman1) January 10, 2015

And the A’s make it officially official:

#Athletics acquire Zobrist and Escobar from Tampa Bay for Jaso, Robertson and Powell; Parrino designated for assignment

— Oakland Athletics (@Athletics) January 10, 2015

Here’s what Keith Law thinks (subscription required):

Oakland continues to try to maintain its contender status for 2015, despite the loss of two major rotation pieces, adding an entire middle infield in one shot by acquiring Ben Zobrist and Yunel Escobar from Tampa Bay for John Jaso and minor leaguers Daniel Robertson and Boog Powell. The Rays get younger and cheaper, likely acquiring their second baseman of the future in Robertson, and avoid losing Zobrist as a free agent after 2015.

Law says the A’s add five to six wins with this move.
