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: 4.52
2. Tampa Bay Rays: 4.25
3. New York Yankees: 4.24
4. Minnesota Twins: 4.11
5. San Francisco Giants: 3.91
6. San Diego Padres: 3.91
7. Philadelphia Phillies: 3.85
8. Colorado Rockies: 3.85
9. Toronto Blue Jays: 3.70
10. Atlanta Braves: 3.57
11. Cincinnati Reds: 3.50
12. Boston Red Sox: 3.47
13. Detroit Tigers: 3.46
14. Florida Marlins: 3.39
15. Los Angeles Dodgers: 3.28
16. Chicago Cubs: 3.26
17. New York Mets: 3.22
18. Washington Nationals: 3.21
19. Texas Rangers: 3.15
20. Oakland Athletics: 3.08
21. Seattle Mariners: 2.77
22. Kansas City Royals: 2.67
23. Los Angeles Angels: 2.53
