Lee expected to pitch Saturday or Sunday

TORONTO -- Rangers starting pitcher Cliff Lee threw an encouraging bullpen session Tuesday and is slated to make his return to the rotation over the weekend against the Yankees.

Whether it will be Saturday or Sunday is undetermined, but manager Ron Washington said it will be no earlier -- dissolving the initial speculation that Lee (sore back) would start Thursday to give Colby Lewis an extra day of rest.

Lee last pitched Aug. 31 against the Royals. Lewis, who was roughed up by the Twins for nine runs in 3 2/3 innings on Saturday, has thrown 170 2/3 frames this year, eclipsing his previous high of 127 set in 2003.
