08:13 AM ET 11.23 | B.J. Upton admitted last week via Twitter that he was "blown away" by the interest some teams had in him. "Can't wait to see how this pans out. #intrigued" The modern hot stove is reduced to a hash tag, and the sentiment extends beyond Upton's 64,000 Twitter followers. The Phillies and Braves have both identified Upton as a priority, possibly their top target. That each team entertained Upton on a visit, which included a tour and meeting with the manager, demonstrated real interest. And so the posturing commences. Numerous agents and executives who have spoken with the Phillies say everything else is on hold until they sign a centerfielder. Thus, the winter has rolled to a slow start with the possibility of heating up rather quickly.
