The Madison Bumgarner market is beginning to take shape, with one executive predicting that the left-hander will sign prior to next week¡¯s Winter Meetings in San Diego.

And while several clubs have been linked to Bumgarner, including the Twins, Reds, White Sox and Braves, a source told MLB.com that a new potential bidder could be entering the fray: the St. Louis Cardinals.

The Cardinals have already brought back Adam Wainwright this winter, signing the veteran to a $5 million deal with another $5 million in incentives included in the contract. With Jack Flaherty, Miles Mikolas and Dakota Hudson locked into the rotation, St. Louis¡¯ rotation appears to be in good shape, though adding an arm of Bumgarner¡¯s caliber would certainly make them better.

Bumgarner is widely expected to land a deal worth at least $100 million, especially after Zack Wheeler received a five-year contract worth $118 million on Wednesday.
