A person familiar with the situation says the Chicago White Sox have agreed to a one-year contract with free agent reliever Matt Lindstrom.
The person spoke to The Associated Press on Sunday on the condition of anonymity because the deal has not been announced, confirming reports by several outlets.
The contract includes a club option for 2014.
The hard-throwing Lindstrom gives the White Sox another reliever to help set up closer Addison Reed. The right-handed Lindstrom pitched a combined 47 innings for Arizona and Baltimore last season, posting a 2.68 ERA with 40 strikeouts and 14 walks. Lindstrom is 13-15 with a 3.64 ERA over six seasons.
