Blue Jays pitcher Roy Halladay is scheduled to start on Friday night against the Mariners. The appearance could be Halladay's final in Toronto if the club decides to entertain trade offers for the pitcher this winter. The team will finish the season in Boston and Baltimore. "I hope not," manager Cito Gaston told the Toronto Sun. "Doc's been great for this organization. He's done everything he could here. But if he moves on, we certainly hope he moves on, out of this division, and out of this league, so we don't have to face him."
