Thorton is most likely going to be the ChiSox closer this season at the age of 34. He is one tough lefty who has a 11.0 K/9 over the past three seasons. I think he will do very well as the new closer and definitely earned this extension.The White Sox and Matt Thornton have agreed to terms on a two-year contract extension with an option for a third year, according to a team release. The deal will pay Thornton $5.5MM annually in 2012 and 2013, while the club option for 2014 is worth $6MM ($1MM buyout). The contract will not affect Thornton's 2011 salary, as the Sox exercised their $3MM option in the fall.
