RealGM Analysis
The Opsera is a statistic RealGM Executive Editor Chris Reina created in order to objectively rank teams by how well they hit (OPS) and pitch (ERA).
In order to determine the Opsera rating for each, we take their OPS, multiply that number by 10 to move the decimal point over one place to the right and then subtract their ERA from that number.
The 2013 Major League season is a week old and while the sample size is small, it's time to take a look at the early returns.
Rankings from the end of last season are in parenthesizes.
