Can Reyes go to the Giants?
Jose Reyes is an obvious candidate to be dealt near the deadline. The Mets aren't playoff contenders as of yet, so what can it hurt to deal him. He's expensive, and Reyes will likely not want to go back to Queens in the coming offseason.
The Giants are the most probable candidate. The Giants have pitchers to give, which will interest the Mets. With Miguel Tejada on and off injuries, and inexperienced Brandon Crawford currently slumping, an obvious trade could be in the works.
The Mets will probably inquire about Jonathan Sanchez because he's a candidate to be flipped by the Mets. Mets could also inquire about youngster Madison Bumgarner, whose contract expires in the 2016 offseason and could be a long term option for the Mets.
Reyes is arguably a top short stop who is batting well over .300 and is a speedy and defensive player.
This means the Giants will have to pay top dollar for Reyes, which can even be Brandon Belt who is doing amazing in the MLB, or it can be Zack Wheeler—a Giants top prospect. Wheeler is a good, young starter who can bring youth to the Mets' organization.
