There is one statistic from the 2012 Major League Baseball season that may be difficult to improve upon in 2013: the number of perfect games pitched.

What are the chances you’ll see three more in a single season? After some serious calculations, Furman math professors John Harris and Kevin Hutson, and Davidson College professor Tim Chartier, say about 1.7 percent.
