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. After several weeks on top of the rankings, the Cardinals have fallen to the second slot in favor of the Yankees. 1. New York Yankees: 4.28 2. St. Louis Cardinals: 4.19 3. Tampa Bay Rays: 4.12 4. San Francisco Giants: 4.09 5. Colorado Rockies: 3.93 6. San Diego Padres: 3.87 7. Minnesota Twins: 3.83 8. Boston Red Sox: 3.80 9. Atlanta Braves: 3.75 10. New York Mets: 3.53 11. Cincinnati Reds: 3.52 12. Texas Rangers: 3.49 13. Detroit Tigers: 3.45 14. Philadelphia Phillies: 3.44 15. Florida Marlins: 3.38 16. Washington Nationals: 3.36 17. Chicago Cubs: 3.34 18. Los Angeles Dodgers: 3.32 19. Toronto Blue Jays: 3.29 20. Oakland Athletics: 3.07 21. Los Angeles Angels: 2.97 22. Chicago White Sox: 2.65 23. Kansas City Royals: 2.58 24. Seattle Mariners: 2.51 25.
