The Phillies have not placed third baseman Placido Polanco on the trading block and they are only interested in dealing him if they can't re-sign shortstop Jimmy Rollins, according to sources. After word spread at the winter meetings that Polanco was available, Phillies personnel made a point of telling several clubs Tuesday that they're "not shopping" Polanco. If Rollins goes elsewhere, however, the Phillies believe they would have to add another significant bat. One potential option would then be to trade Polanco and sign free-agent third baseman Aramis Ramirez.
