A “baseball hangover” isn’t what happens to an adult who downed a few $9 brews at the ballpark. It’s the distant look of sleep deprivation in the eyes of a kid struggling through ninth-grade English after staying up until 10:15 watching a typical game the night before.

The St. Louis Cardinals are making a small effort to minimize those hangovers. Home games on school nights will start half an hour earlier, with the first pitch at 6:45 instead of the traditional 7:15. This means kids who stay up for all nine innings will get to bed before 10 p.m. most games, and little sluggers may get to see more than the top two frames.
