THT has an interesting article about the current "luck leaders" among pitchers. Contreras made 1 unlucky list (LOB%) and 1 lucky list (HR/FB). Garland made the latter list as well; interesting that 2 guys with home games in the Cell are on there. Other notes: Danks lucky with high LOB%, Buehrle & Garland lucky with low BABIP, Buehrle lucky with low line drive rate and Garland unlucky with high line drive rate.
So, Buehrle would be the luckiest Sox pitcher this season, although no Sox pitcher really stands out as very lucky or unlucky. Vazquez wasn't on any of the lists, which is interesting as well.
