Thomas Has Pact Extended

Frank Thomas of the Chicago White Sox, who wouldn’t have been eligible for free agency until after the 1997 season, agreed to a four-year contract extension through 1998 worth about $28 million.

The team gets two option years that could make the deal worth about $42 million for six seasons. The first baseman, who had a base salary of $900,000 this year, already is signed for 1994 at $2.5 million.
