The White Sox offered salary arbitration to free agent Mark Buehrle on Wednesday.

The move, which was expected, means the Sox will receive a draft pick as compensation should the 32-year-old left-hander sign with another team. Buehrle has until next Wednesday to accept or ­decline. He is not expected to ­accept, but he might still negotiate with the Sox.

The Sox declined to offer arbitration to free-agent left fielder Juan Pierre, who is hoping to catch on with another team. The Sox are expected to replace Pierre in the leadoff spot with Alejandro De Aza. Whether De Aza plays left field or another outfield position has yet to be determined.

The decisions on Buehrle and Pierre were expected.
