Yesterday was Opening Day, that unofficial national holiday when the boys of summer take to the field in pursuit of a World Series title.

While baseball may be one of America’s oldest sports, Major League Baseball is actually at the forefront of technology, with its popular MLB At Bat mobile app providing fans with up-to-date scores, radio broadcasts, and even streaming video of games. And as Erica Ogg of GigaOm points out, yesterday the app paid off big:

Major League Baseball executives are celebrating a different Opening Day milestone: the skyrocketing popularity of the league’s official mobile app, At Bat. On Tuesday, MLB announced that the At Bat app, which is available for iOS, Android and BlackBerry, was accessed 6 million times on Monday, the first day of baseball’s 2013 season. That’s double the amount of use the app saw on Opening Day 2012.
