However, I do think Sandy Alderson will consider moving Jenrry Mejia, Wilmer Flores, Jeurys Familia or even guys like Daniel Murphy and Lucas Duda, but ONLY if it is a deal that helps the team this year and through 2014 and doesn't add a ton of payroll.
For instance, I don't believe he will (nor should he) trade top pitching prospects for Padres OF Carlos Quentin, because Quentin is a free agent at the end of this season. However, I could totally see the Mets expanding a deal, paying $10 million in cash and giving up just mid-level prospects to get Quentin and reliever Huston Street. The thing is, other teams are probably willing to do the same, so expect the Padres to shop this as long as they can, while trying to raise the price in talent they'll get back in a deal.
By the way, I also don't see Alderson giving up top prospects for D-Backs OF Justin Upton - who is reportedly being shopped by Arizona - mostly because Upton is making a lot of money through 2015 and his power is evaporating.
In the end, I bet towards the end of the month the Mets eventually trade cash and a mid-level prospect or two to get a catcher (say, Rockeis C Ramon Hernandez) and a reliever (say, Matt Reynolds, or maybe Street). I don't see the Mets making a multitude of deals. Instead, I think they'll aim for one or two smaller deals that help to solidify the roster and support their current core, while not disrupting the upper ring of their farm system.
