CINCINNATI (AP) -Pittsburgh Pirates left-hander Zach Duke will get an extra day before his next start to take care of a callus on the middle finger of his pitching hand.

Duke was scheduled to start Thursday in the final game of a series at Cincinnati. Instead, left-hander Phil Dumatrait will start on four days' rest.

Duke is coming off a 12-3 loss to Carlos Zambrano and the Chicago Cubs on Friday in Pittsburgh. He lasted five innings in that game, allowing four runs.

The Pirates plan to start him Friday against St. Louis.

Dumatrait, who was claimed off waivers from Cincinnati last October, is 1-2 with a 4.05 ERA in five starts and 10 relief appearances. He went 5 2-3 innings in a 5-4 win over the Cubs on Saturday night.Copyright © 2005 The Associated Press. All rights reserved.
