Chicago White Sox right-hander Gavin Floyd agreed to a $15.5 million, four-year contract with a club option for 2013 on Sunday, according to the Associated Press. The 6’5, 230-pound 26-year-old starter had the best year of his career for the White Sox in 2008, going 17-8 with a 3.84 ERA and a 1.26 WHIP. In addition, he has gone 25-18 in 73 games over portions of five big league seasons with the Philadelphia Phillies and White Sox. Floyd will make $750,000 this year, $2.75 million in 2010, $5 million in 2011 and $7 million in 2012, and the White Sox hold a $9.5 million option for 2013. Floyd had been set to make $520,000 this year under a one-year deal agreed to Feb. 25. He would have been eligible for arbitration after this season and for free agency following the 2012 season. Fellow pitcher John Danks and outfielder Carlos Quentin were also approached by the team about multi-year deals following breakout campaigns last year, but only Floyd agreed to a deal.Evan Nuckles is a staff member of the Business of Sports Network, which includes The Biz of Baseball, The Biz of Football, The Biz of Basketball and The Biz of Hockey.
