Pedro Gomez of ESPN is reporting the Phillies and Diamondbacks have begun engaging in preliminary talks to send Cliff Lee and cash to the Diamondbacks for outfielder Justin Upton. Jeff Passan of Yahoo! Sports believes that the Diamondbacks are in the market for a shortstop and, because the salaries do not match, Passan believes that there would be more in this trade and possibly three or four teams, citing the Diamondbacks’ history of completing multi-team trades. More on this as it develops.
