By Christopher Reina The Opsera is a statistic I created in order to objectively rank teams by how well they hit (OPS) and pitch (ERA). In order to determine a team's Opsera, I take their OPS, multiply that number by 10 to move the decimal point over one place to the right and then subtract the team's ERA from that number. 1. St. Louis Cardinals: 4.58 2. New York Yankees: 4.26 3. Tampa Bay Rays: 4.12 4. San Francisco Giants: 3.97 5. San Diego Padres: 3.90 6. Minnesota Twins: 3.81 7. Colorado Rockies: 3.79 8. Philadelphia Phillies: 3.79 9. Boston Red Sox: 3.79 10. Toronto Blue Jays: 3.74 11. Atlanta Braves: 3.70 12. Cincinnati Reds: 3.56 13. Detroit Tigers: 3.50 14. Los Angeles Dodgers: 3.34 15.
