Most pitchers usually don't have high expected BABIPs unless they're absolutely getting hammered.
It's not the most accurate, but generally LD%+.12 is a rough estimate of what BABIP should be.
Lester has a 19% LD, so his BABIP is too high.
Smoltz is at 19.6%, so they're both just unlucky. He's also lucky that his ERA is low with that BABIP, although he's been pitching good (if that makes sense).
