Tom Paciorek had four hits and four RBI and Floyd Bannister equaled his career high of 11 strikeouts, lifting the Chicago White Sox to a 9-3 victory tonight over the Baltimore Orioles.

It was the sixth straight loss for the Orioles, who dropped from first to third place in the American League East, one game behind Milwaukee.

"We're going to have to get our act together and turn it around," Orioles Manager Joe Altobelli said. "We only have 52 games left, so we're going to have to turn it around soon. And we're facing a pretty hot team."

Bannister (10-9) managed his seventh straight victory and left with one out in the seventh.

The 28-year-old left-hander allowed six hits and walked one. Loser Allan Ramirez (4-3) lasted only 2 1/3 innings.

Ken Singleton's two-run homer in the second inning gave Baltimore the early lead.

But Chicago sent 10 batters to the plate and scored six runs in the third. Carlton Fisk cut the lead to 2-1 with an RBI single then Paciorek doubled in three runs. Vance Law then doubled in two runs.

The White Sox added three runs in the sixth on RBI singles by Fisk, Harold Baines and Paciorek.

Bannister left after singles by Singleton and Lenn Sakata in the seventh. Sakata's hit was his first against the White Sox in 67 career at bats.

Salome Barojas relieved Bannister then walked Rick Dempsey and John Shelby to produce the Orioles' third run.
