The Madison Bumgarner sweepstakes has officially begun.

With the Giants reportedly telling rival teams that they are ready to begin the process of listening to offers for one of the great big-game pitchers of all time, major questions have begun to emerge.

What’s with Bumgarner’s no-trade clause? Who are the suitors? Is this a battle between, say, the Yankees, Phillies and Braves?

And now this one: If Bumgarner’s next team wants to try to extend his contract past 2019 and keep him away from free agency in the winter, how much would it cost?

Not as much as you might think, at least in the mind of one connected baseball person that spoke to ESPN MLB insider Tim Kurkjian.
