You could have downloaded Baseballz 1.1 for Mac from our software library for free. The application lies within Theming Tools, more precisely Screensavers. This Mac application was originally developed by Skyrocket Software.
From the developer:
Baseballz is a screensaver tribute to that distinctly American sport.
The smell of fresh cut grass, and the taste of hot dogs and peanuts, means it's baseball season once again! Little league, minor league, or the big leagues, we love every minute of it.
America's oldest pastime began professionally in the 1870's, but it's roots go back to 1839, when Abner Doubleday devised the game of baseball in Cooperstown, N.Y.
