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 Tuesday, May 21 games.

Rankings from last week are in parenthesizes.


1. (2) Texas Rangers – 4.21

The Rangers are mashing the baseball (.775 OPS) and keeping hitters at bay (3.54 ERA).

T2. (1) Detroit Tigers – 4.04

How huge would Miguel Cabrera be if he played in a major market?

The Cardinals average 3.12 strikeouts per walk.
