From MLBTradeRumors, quoting Geoff Baker of the Seattle Times:
Baker hears that the Red Sox gave the Mariners the chance to choose five of the following players in exchange for Felix Hernandez:
- Clay Buchholz
- Daniel Bard
- Justin Masterson
- Nick Hagadone
- Michael Bowden
- Felix Doubront
- Josh Reddick
- Yamaico NavarroThe Mariners apparently turned down the deal, at which point the Padres became involved in discussions about a possible three-way trade. The Mariners would have received Adrian Gonzalez, Buchholz and prospects in the deal. They would have sent Felix to the Red Sox and dealt Brandon Morrow, Phillippe Aumont and Carlos Triunfel to the Padres, who would have received prospects from the Red Sox as well. In the end, Baker says the Mariners nixed the deal.
One presumes this was the deal Theo said the Sox came "close" on. The fact that they got down to what prospects were being sent where indicates this must have come very close indeed. Clearly, the Mariners simply didn't have a desire to move King Felix this time around.
