MLB.com’s Corey Brock quotes Kevin Towers as saying a free agent signing is unlikely, which implies that Shannon Stewart is not on the radar. Towers still may add an outfielder via trade.
The idea of the Padres and Mariners being interested in Stewart was misconstrued a bit. Jerry Crasnick said Towers "might be tempted to look at a free agent" and that the Mariners "seem like a potential fit." My summary of his article said the Mariners and Padres were possibilities. I should’ve been more clear that Crasnick was speculating on those two clubs rather than reporting specific interest – sorry about that. As for Stewart, only the Blue Jays have made an offer. He came up in the Toronto organization and had some nice seasons for them.
Back to the Padres. Brock adds that Michael Barrett is not likely to be traded – Towers likes having two starting-caliber catchers on the roster. Not an ideal situation for Barrett, but it was his choice to accept the Padres’ offer of arbitration.
