The number I am looking right now is the Simple Rating System (SRS) for each team. The Simple Rating System takes into account run differential and strength of schedule. The average SRS number is 0.
So far it is the Braves leading the way with an impressive 3.2 SRS. The other thing you will notice is how the National League dominates the Top 5.
Next we look at the five worst teams and you will notice they all come from the American League with the White Sox leading the way for worst team so far in the major leagues.
