While fans may hope for a bright sunshine when attending a baseball game, the players may feel differently. A study released by Kent State University in early 2011 pulled data from more than 35 thousand MLB games between 1987 and 2002 to study the correlation of cloud cover and performance.

Several variables were examined, including pitching, fielding performance, and batting, among others. Even home and away statistics were evaluated. The study suggests that offensive production suffers during bright, sunny days. The hitter has a much harder time concentrating on the pitch when there is a glare. Conversely, pitching performances improved during bright sunny days.

Even certain stadiums showed a strong correlation between player performance and cloud cover. Furthermore, all impacts affected what is known as the "home field advantage". It appears that the home team wins more often when skies are clear.
