Per ESPN Chicago and Rotoworld
According to ESPN Chicago, the Cubs have traded Jake Fox and Aaron Miles to the A's for right-hander Jeff Gray and two minor-leaguers.
Few details have been revealed, though this is certainly an odd one. Fox was stuck behind a few players on Chicago's depth chart and should get a better crack at playing time in Oakland. That part of the deal makes sense. But it's a wonder why A's GM Billy Beane and Co. would want Miles. It's probably safe to assume that the prospects involved are not of the "highly-touted" variety.Dec. 3 - 6:09 pm et
