CHICAGO -- White Sox catcher Geovany Soto has declined his option for next season and become a free agent.
The NL Rookie of the Year with the Cubs in 2008, he agreed to a minor league contract with the White Sox in January. The 34-year-old Soto missed most of last season because of a right elbow injury that required surgery and batted .190 in 13 games.
The White Sox also reinstated outfielder Charlie Tilson and right-hander Zach Putnam from the 60-day disabled list.
The team announced the moves on Thursday.
