I'd also suggest the following lineup vs LHP
drew
kotsay
berkman
lowell
konerko
rollins
lawton
castillo, c
castillo, 2b
berkman not the ideal #3 because of his low xtra bases, but I wouldn't want to put him lower in the order and lowell/konerko fit well at #4/5. The two lefties at the top is a little unconventional but they both have killer OBP vs LHP and should be filling the base paths for the rest of your offense.
