According to Ken Rosenthal of FOX Sports, Jason Hammel and Jeff Samardzija are heading to the Athletics in a trade for top prospect Addison Russell. Hammel has been on the block for awhile and was expected to be dealt before the end of the weekend. He has had a tremendous first half, posting a 2.98 ERA, 1.01 WHIP and 97/21 K/BB ratio over 102 2/3 innings. He and Samardzija will make an already deep and talented A's rotation even better.
