The Mets today signed ex-Yankee and ex-Brave Mike Stanton to a frighteningly long 3-year contract. Stanton is familiar to New Yorkers as the lefty who wore No. 29 for Satan’s Minions. His arrival seems to portend a conflict with the current 29, Met starter Steve Trachsel. Dec. 18 Update: Stanton posed for photographs today wearing a No. 32 jersey.
