Felix Hernandez and the Seattle Mariners are working on a $175 million, seven-year contract that would make him the highest-paid pitcher in baseball, according to a person with knowledge of the situation.

The source said Seattle would add $134.5 million over five years to the contract of the 2010 A.L. Cy Young Award winner, whose current deal calls for him to receive $40.5 million over the next two seasons.

General manager Jack Zduriencik said he couldn't comment when reached Thursday, and Hernandez's representatives didn't return messages.

Hernandez, 26, is 98-76 with a 3.22 ERA in eight seasons in Seattle.

    The league reinstated Gregg Williams after suspending him for his role in the New Orleans Saints bounty scandal. Tennessee then added him to coach Mike Munchak's staff as a senior defensive assistant. Commissioner Roger Goodell cited several reasons for reinstating Williams, including that Williams accepted responsibility for his role in the bounty program. Williams was defensive coordinator for the Saints from 2009-11 and was hired in the same position by St. Louis in January 2012 before being suspended. "I'm grateful for this opportunity," said Williams, who was the Titans defensive coordinator from 1997-2000.
