Howard was awarded a record arbitration award of $10 million in 2008 and signed a three-year extension worth $54 million, a year later.
The new deal also includes a limited no-trade clause, which will actually become moot early in the 2015 season when Howard becomes a 10-and-5 player. At that point, Howard will have ten seasons in the majors and all with the same club, meaning that he can veto any deal.
Cole Hamels, Raul Ibanez, Ryan Madson and Jimmy Rollins are also eligible for free agency following the 2011 season. After the 2010 season, outfielder Jayson Werth is eligible for free agency, as well.
