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.  

 

All statistics are through Monday, April 22 games.

Rankings from last week are in parenthesizes.

 

1. (1) Atlanta Braves – 5.14

Chris Johnson is hitting .407 and Justin Upton has nine home runs.
