The Opsera is a statistic I created in order to rank teams by how well they hit (OPS) and pitch (ERA). In order to determine a team's Opsera, I take their OPS, move the decimal point over one place to the right and then subtract the team's ERA from that number. 1. Los Angeles Dodgers: 4.08 While Clayton Kershaw and Chad Billingsley are a little behind the frontline duo in San Francisco, the Dodgers have received very good pitching from their third starter, Randy Wolf, who has a 3.45 ERA. 2. Boston Red Sox: 3.92 After shaky starts to the season, Josh Beckett and Jon Lester have corrected the ship with improving strikeout rates and ERAs below 4.00. 3. Tampa Bay Rays: 3.88 Evan Longoria has hit for an OPS of 1.133 in April, .938 in May, but just .752 and .552 respectively in June and July. 4. New York Yankees: 3.74 Alex Rodriguez has an OPS of 1.000 with 41 RBIs in 104 at bats with runners on base. 5. St. Louis Cardinals: 3.61 Every slot in the Cardinals lineup has an OPS under .765 with the exception of the 1.161 three hole. 6. San Francisco Giants: 3.54 Between Tim Lincecum, Matt Cain and the best bullpen in baseball, the Giants have the best ERA in baseball, good enough to offset their 28th ranked OPS of .705. 7. Seattle Mariners: 3.47 Seattle's starting pitching has been remarkable, with Felix Hernandez posting a 2.53 ERA, followed by Erik Bedard's 2.63, Jarrod Washburn's 2.96 and even Jason Vargas with a 3.82 mark. 8. Colorado Rockies: 3.45 The Rockies have remained competitive, though the departure in left field created by the Matt Holliday trade has created a .771 OPS situations for the club. 9. Toronto Blue Jays: 3.43 Toronto is getting career seasons out of players like Aaron Hill and Marco Scutaro, while Vernon Wells and Alex Rios (.723 and .732 OPS respectively) are not producing as the middle of the order hitters they are signed to be. 10. Detroit Tigers: 3.41 Clete Thomas is 7-for-13 since being called back up, which has made avoiding giving Magglio Ordonez his at bats an easy decision. 11. Atlanta Braves: 3.40 Jair Jurrjens and Javier Vazquez have delivered with 2.91 and 2.95 ERAs respectively, but Derek Lowe has been a disappointment with an 8-7 record and 4.39 ERA. Lowe has rebounded, however, after a disastrous June. 12. Chicago White Sox: 3.39 Comiskey or Cominskey, the White Sox have an ardent supporter in Barack Obama and even a completely rejuvenated Jose Contreras, who had a 2.15 ERA in June and a 1.88 mark in July after his 12.86 May. 13. Chicago Cubs: 3.38 Carlos Zambrano (.719) has a higher OPS than Alfonso Soriano (.711), who hasn't hit at all since April. 14. Texas Rangers: 3.38 Thanks to the consistency throughout the Texas lineup, the Rangers have remained in the AL West hunt without Josh Hamilton. 15. Minnesota Twins: 3.32 Predictably, Joe Mauer's power numbers have dipped significantly, with just four homers after the blazing 11. 16. Philadelphia Phillies: 3.32 The Phillies have four sluggers (Raul Ibanez, Ryan Howard, Chase Utley and Jayson Werth) with 20 or more homers already. 17. Houston Astros: 3.14 Former Atlanta starters Russ Ortiz and Mike Hampton have made somewhat surprising comebacks in 2009 with the Astros. 18. Los Angeles Angels: 3.08 The Angels have leaned heavily on Torii Hunter and Juan Rivera due to the Vladimir Guerrero injury, but Kendry Morales and Bobby Abreu have filled in nicely as well. 19. Milwaukee Brewers: 3.03 Yovani Gallardo has made Milwaukee's front end pitching serviceable without CC and Sheets, but it has been thin behind him and they have a starting ERA of 5.03. 20. New York Mets: 3.02 The lack of organizational depth has been highlighted by the run of injuries. 21. Arizona Diamondbacks: 2.97 Dan Haren has an outstanding 2.05 ERA, but cam he shake that 2nd half career split of 4.12 compared to 3.08 for the first half? 22. Florida Marlins: 2.96 Josh Johnson continues to post an ERA below 3.00, but Chris Volstad and Ricky Nolasco haven't been able to find consistency behind him. 23. Pittsburgh Pirates: 2.89 It looks like the Pirates will finally trade Freddy Sanchez, but it is difficult to imagine a team giving up too much for a 31-year-old with a career .763 OPS. 24. Cincinnati Reds: 2.83 Not consistently having Joey Votto's .351/.433/.594 bat in the lineup has hurt Cincinnati's chances of competing. 25. Kansas City Royals: 2.69 Alberto Callaspo is a few outs away from giving the Royals a lineup without any .800 or better OPS hitters. 26. Oakland Athletics: 2.63 Speaking of lineups without any .800 or better OPS hitters, the Oakland A's have one. 27. Baltimore Orioles: 2.52 Matt Wieters has an .863 OPS through his first 23 at bats in July after his slow start in May and June. 28. Washington Nationals: 2.32 John Lannan has a workmanlike 3.70 ERA despite a 4.02 K/9 rate. 29. Cleveland Indians: 2.25 When healthy, Travis Hafner has had a comeback season with a .944 OPS and nine homers in 135 at bats. 30. San Diego Padres: 2.11 The Padres have a 5.77 ERA on the road, 27th in baseball.
