The White Sox agreed to a $10 million, four-year contract Friday with Cuban infielder Dayan Viciedo. Viciedo will receive a $4 million signing bonus and be paid $1 million in 2009, $1.25 million in 2010, and 2011 and $2.5 million in 2012. "My best defensive position is third base. It's the position I've always played and the position I feel most comfortable in," Viciedo said through a translator.
