White Sox exercised RHP Matt Lindstrom's $4 million club option for the 2014 season. It was that or pay him a $500,000 buyout and let him walk. Thornton posted a 3.12 ERA in 60 2/3 innings of relief this season for Chicago. The 33-year-old righty will serve as a setup man for the Pale Hose again in 2014.
