According to Sean McAdam at the Boston Herald, the Red Sox have been "very aggressive" in their pursuit of Adrian Gonzalez from the Padres, but their offers have been "rebuffed."
The Adam LaRoche acquisition may have just been one domino falling before a major acquisition, McAdam notes, as the Sox have been spending the final week before the trade deadline to hunt for an impact bat. Their interest in Victor Martinez is well-known, but a source tells McAdam the cost for Martinez has been "prohibitive." McAdam also says that if another deal is in the works, it will be for a player "that can upgrade the Sox not only this year, but for several seasons to come."
The Padres haven't formally put Gonzalez on the trading block, and indications are that the first baseman is staying put.
