The Padres are talking extensively about a trade involving Adrian Gonzalez. The Red Sox have been the most notable potential trade partner, but other teams are involved. The likelihood of a trade isn't known, but one source says the situation involves "pretty good discussions'' with multiple teams. Padres chairman Jeff Moorad told the San Diego Union-Tribune that there are at least three teams talking to San Diego about Gonzalez, whose value is enhanced by a bargain $5.9 million salary in 2011.
