Piniella plans to drop shortstop Ryan Theriot to the eighth spot against left-handed pitching. The corresponding move is to bat Marlon Byrd at lead-off against lefties and move Jeff Baker to the second spot.
Piniella also stated Xavier Nady would bat fourth against left-handers, however Nady can't play every day due to his recovering right elbow. With Nady batting clean-up, that also would drop Aramis Ramirez to the No. 5 hole.
The Cubs will face a left-hander in three of the next four games against the New York Mets.
