The only thing missing in the Gio Gonzalez sweepstakes is a mystery team. According to Buster Olney of ESPN, the Oakland Athletics are moving closer to a Gio Gonzalez trade, with the bidding down to two teams.
One of the two teams are the Washington Nationals, who are pursuing a four-for-one deal with Oakland. Athletics have been looking at two of Washington's top prospects, catcher Derek Norris and pitcher Brad Peacock, as possible pieces to a deal. I speculated earlier today the Nationals would have to include their top prospect outside of Bryce Harper and Stephen Strasburg, sixth-overall draft pick in this past year's draft - third baseman Anthony Rendon.
Olney speculates the mystery team could be the Miami Marlins or Boston Red Sox. Both could put together good packages as well and have been linked to Gonzalez recently. For what it is worth, the Nationals prospects are more major-league ready and probably less risky than either of the two systems.
As far as mystery teams go, I'm going to throw in the Toronto Blue Jays for good measure. They could be inclined to offer Oakland the moon after missing out on Yu Darvish and they certainly have the minor league system to do so. Who are you throwing in there as the mystery team?
