RealGM.com Team Rankings For The Week Of September 15th By Andrew Perna 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. Below are the rankings through the Wednesday, September 14th games: The rankings from last week are in parenthesizes. 1. (1) New York Yankees - 4.25 The Yankees do not have the best record in baseball, but they own the best run differential (+206) by a wide margin. 2. 2) Philadelphia Phillies - 4.20 The Phillies became the first team to punch their playoff ticket on Wednesday and locking up the National League East is around the corner. 3. (4) Texas Rangers - 4.07 The Angels are keeping the pressure on Texas, but at least the Rangers can sleep a little better knowing the Wild Card is another possibility as the Red Sox continue to struggle. 4. (3) Boston Red Sox - 4.01 Do I think the Rays will leapfrog the Red Sox? No, but the Rangers and Angels could be another story. 5. (6) St. Louis Cardinals - 3.76 Technically, the Cardinals are alive. 6. (5) Milwaukee Brewers - 3.75 A mid-September swoon will be soon forgotten if they can get back on track by the end of the month. 7. (10) Detroit Tigers - 3.64 Detroit is hot at the perfect time, but with the American League Central all but locked up, are they going to run out of gas in October? 8. (7) Atlanta Braves - 3.63 The Braves are in control of the Wild Card and I doubt the Brewers or Diamondbacks want to face them in the divisional round. 9. (8) Tampa Bay Rays - 3.60 Joe Maddon deserves Manager of the Year honors. The Rays have been able to get back into playoff contention because of poor play in Boston, but he has kept his young crew focused on controlling only what they can. 10. (9) Los Angeles Angels - 3.59 If they are not able to surpass either the Rangers or Red Sox, the Angels will be the best team in baseball not to make the postseason (sorry, Tampa Bay). 11. (12) San Francisco Giants - 3.51 12. (11) Arizona Diamondbacks - 3.49 13. (16) Washington Nationals - 3.25 T14. (13) Los Angeles Dodgers - 3.24 -- (14) Cincinnati Reds - 3.24 16. (19) Colorado Rockies - 3.13 17. (18) New York Mets - 3.11 18. (15) Chicago White Sox - 3.09 19. (22) Florida Marlins - 3.07 20. (17) Oakland Athletics - 3.06 T21. (T20) Toronto Blue Jays - 3.00 -- (T20) San Diego Padres - 3.00 23. (23) Cleveland Indians - 2.97 24. (T25) Kansas City Royals - 2.84 25. (24) Pittsburgh Pirates - 2.83 26.
