Chicago ? Hoping to bolster their starting rotation, the World Series champion White Sox agreed to acquire right-hander Javier Vazquez from Arizona for right-hander Orlando Hernandez, reliever Luis Vizcaino and minor-league outfielder Chris Young, a baseball official said Wednesday.

The deal is contingent on the players passing physicals and must be approved by commissioner Bud Selig because Arizona is sending the White Sox cash to help pay part of Vazquez’s salary.

The official spoke on condition of anonymity because the trade had not been finalized. The agreement was first reported by the Chicago Tribune and Newsday in Wednesday’s editions.

It would be the fourth major offseason move by the White Sox since Chicago won its first World Series since 1917. The White Sox re-signed first baseman Paul Konerko and traded for DH Jim Thome and utility player Rob Mackowiak.

Vazquez filed a formal trade demand Nov. 10.

He is owed $11.5 million next year and $12.5 million in 2007.

Vazquez was obtained by the New York Yankees from Montreal after the 2003 season and was an All-Star in his first season with New York, going 14-9 with a 4.75 earned-run average.
