Cole Hamels touts a big Day/Night split:

In his career, Hamels has a 2.70 earned run average in night starts and a 5.92 ERA in day starts. This season (admittedly only five games old for Hamels), he has a league-leading 0.56 ERA at night and a 5.71 ERA during the day.

The statistics have gotten the attention of manager Charlie Manuel and pitching coach Rich Dubee and, sooner rather than later, Hamels' starts could be manipulated to take advantage of his strengths and avoid what has so far been a weakness.

I'd like the article better if they talked to the catcher at least and asked him if he saw Hamels' pitches better in the day time. But three starts from now, Manuel has the choice of pitching Cole at night or pushing him back a day for an afternoon game. We'll see what happens then.
