As of this morning, the deal had four players coming to the Mets and three to the Blue Jays, according to Mike Puma of the New York Post (Twitter links).
Toronto also wants a catcher back in the deal, and that could be Thole. The Mets have discussed getting pitching prospect Noah Syndergaard in the deal as well, Puma tweets.
The two teams are inching towards the finish line, a source tells Passan (via Twitter). At least some players' medicals have been reviewed and a deal is imminent.
Jon Heyman of CBSSports.com says the two sides have agreed that d'Arnaud can be the centerpiece of the trade after the Mets rejected a Gose/J.P. Arencibia package (all Twitter links). Once they finalize the rest of the players involved, it's believed Dickey will talk about an extension with Toronto.
It is believed from what I read that the Mets will send Pitcher R.A. Dickey, Catcher Josh Thole, and either RHP Jeurys Familia or IF/OF Wilmer Flores for Catcher Travis d'Arnaud, Catcher John Buck, OF Anthony Gose, and LHP Noah Syndergaard.... Nothing Confirmed yet!
