The White Sox will go with their new regular lineup -- meaning Kevin Youkilis is batting second -- for the start of a weekend series against the Blue Jays' lefty Aaron Laffey.

That means left-handed bats Alejandro De Aza, Adam Dunn and A. J. Pierzynski will be playing. Dunn is batting only .163 against southpaws.

The lineup behind Jake Peavy:

De Aza, cf

Youkilis, 3b

Dunn, 1b

Konerko, 1b

Rios, rf

Pierzynski, c

Viciedo, lf

Ramirez, ss

Beckham, 2b

Peavy, p
