After working late into Thursday night, the Mets and Reds are picking up momentum on a trade that would bring outfielder Jay Bruce to New York and send righthander Zack Wheeler to Cincinnati, sources said Friday morning. Hours before baseball's non-waiver trade deadline, the teams were reviewing the medical reports of players involved, which has already proven to be an obstacle for the Mets once this week. Other players in the deal were not known Friday morning.
