CHICAGO (AP) _ The Chicago White Sox acquired reliever Alan Embree from the San Francisco Giants on Friday for minor leaguer Derek Hasselhoff.

Embree, a left-hander, is expected to be in Chicago in time for Saturday's game against the Baltimore Orioles.

To make room for Embree on the 40-man roster, the White Sox moved reliever Bill Simas, out for the year after having ligament replacement surgery, to the 60-day disabled list.

The White Sox have been looking for another left-handed reliever since Kelly Wunsch went on the disabled list June 19 with what is probably a torn rotator cuff. Wunsch is scheduled to visit Dr. James Andrews on July 9, and could need season-ending surgery.

Embree is 0-2 with no saves and an 11.25 ERA in 22 appearances for the Giants this year. He is 17-17 with four saves and a 4.85 ERA in eight seasons with Cleveland, Atlanta, Arizona and the Giants.

He's played in nine postseason games, including four appearances during the 1995 World Series.

Hasselhoff was 6-1 with six saves and a 2.03 ERA in 34 relief outings for Triple-A Charlotte. In seven seasons in the minor leagues, he's 43-17 with a 3.54 ERA.

The Giants also recalled left-handed reliever Chad Zerbe from Triple-A Fresno.

Zerbe, who was 1-1 with a 1.23 ERA in nine games for Fresno, was in uniform Friday night for the Giants' game against the St. Louis Cardinals.
