The Pirates are shopping shortstop Jack Wilson, and the Blue Jays are known to be interested. One would expect the Bucs to be happy with the salary relief and maybe ask for a token prospect. Instead, Dave Littlefield asked about Troy Glaus.
Now, it was just an inquiry, and the Jays quickly shot it down. Obviously we don't know how the phone call went, so Littlefield might've devised a reasonable trade scenario involving additional players. The Pirates could definitely use a big bat like Glaus, but he does not seem likely to approve a trade to Pittsburgh even if the two sides did agree on the players.
It's hard to tell just how available Glaus is, but a recent report indicates that he can be had. A return to the Angels still seems most likely.

Izturis is here already so that makes Wilson expendable, right? This may be a crapshoot and high skied dreaming on the Bucs part, but at least they are looking at things to make this team better. I haven't heard much other interest in Glaus so maybe it could work.
