I think you've got it right: Morse, Guti, and Saunders.
As for those who seem to think Bay has a really good shot to play, I can only tell you I'm a Mets fan and have followed Jason's travails for two years. I can't imagine that all this faith in him comes from people with a real knowledge of his struggles. He hasn't been able to hit his weight for a long time. I mean, it was sad -- bad at-bat after bad at-bat, with only the rare glimmer that quickly faded back into a series of failures at the plate. He's shown almost nothing.
Heck, I'd love to see him resurrect his former self at the plate. But there's zero evidence that he can, and we'll only know if he has anything left when he picks up a bat in spring training. This is an extreme long shot, and Z knew it. It was worth taking, because the Mets are paying him $21M and the M's only had to toss in a chicken feed salary. If he's got something, it's a windfall. If not, no big loss to the franchise.
