Fox Sports reported Sunday evening that although the front-runners for James Shields are still unknown, he is expected to sign a deal of at least five years and $100 million.

The report also notes that some league executives believe any offer of that magnitude would be surprising, considering Shields is 33 years old and coming off eight consecutive seasons of 200-plus innings.

The latest news leaves the market for Shields unclear, as several teams would likely bow out of the running at the expected price.
