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. New York Yankees: 4.05 The Yankees have the 4th best ERA in baseball since the All-Star break, with 14 saves as they've created a ton of separation in the AL East. 2. Los Angeles Dodgers: 4.04 Andre Ethier and Matt Kemp have become the monster young outfielders we expected this season, with OPS' of .872 and .900 respectively. 3. Tampa Bay Rays: 3.75 Who had Jason Bartlett in their preseason poll to lead the Rays in OPS? Or Ben Zobrist for that matter? Those two have OPS' of .934 and .929, ahead of their big three of Evan Longoria, Carl Crawford and Carlos Pena. 4. St. Louis Cardinals: 3.73 Matt Holliday is hitting .430/.462/.720 in his first 93 at bats with Cards. 5. Atlanta Braves: 3.72 The Braves have the best fielding independent ERA in baseball with a mark of 3.69, slightly ahead of San Francisco's 3.74. 6. Boston Red Sox: 3.70 Daniel Bard has a 5.56 ERA since the break. 7. Colorado Rockies: 3.63 Ubaldo Jimenez, Jorge De La Rosa and Jason Marquis have all been excellent since the All-Star break, with ERAs of 2.49, 3.00 and 3.18 respectively. 8. Texas Rangers: 3.58 The Rangers are second in isolated power with a mark of .196; the highest last season was from the White Sox with just .185. 9. Philadelphia Phillies: 3.57 Philadelphia pitchers have an excellent LOB% of 75.2%. 10. Chicago Cubs: 3.50 The Cubs have finally demoted Kevin Gregg and the club is 8th in blown saves with 17. 11. San Francisco Giants: 3.48 The Giants have the best UZR in all of baseball, barely edging out the Mariners; last season they were ranked 9th. 12. Toronto Blue Jays: 3.46 Aaron Hill and Adam Lind have 28 and 24 homers apiece, which is what they needed from Alex Rios and Vernon Wells. 13. Chicago White Sox: 3.44 Alex Rios has hit safely in five of his first six games with the White Sox, but he has an OPS of just .588. 14. Detroit Tigers: 3.32 The Tigers have a very human OPS of .734 since the break. 15. Arizona Diamondbacks: 3.27 Mark Reynolds has 14 homers since the All-Star break. 16. Los Angeles Angels: 3.24 The Angels have an outstanding .864 OPS since the All-Star break, while scoring 218 runs. 17. Florida Marlins: 3.24 The Marlins have recorded 10 or more hits in 14 consecutive games. 18. Seattle Mariners: 3.20 Checking in on Ken Griffey, he has a .819 OPS in August and .723 for the season. 19. New York Mets: 3.00 The Mets have hit just one homer for every 56.2 at bats, while the Yankees have been twice as effective with one for every 23.0 at bats. 20. Minnesota Twins: 2.98 The Joe Mauer for MVP campaign is now in full swing and he truly doesn't have a peer in the category. As much as I'd like to see him become Broadway Joe in the Bronx, I sincerely hope he remains St. Paul Joe at the new Target Field for the remainder of his career. This is the winter that they need to sign him before the Yankees (or Red Sox for that matter) make him an offer he can't refuse and the Twins can't match. 21. Milwaukee Brewers: 2.81 The Brewers have given up 1.39 homers per nine innings, which is the worst ratio in the MLB. 22. Houston Astros: 2.76 The Astros have grounded into an MLB-worst 112 double plays. 23. Cleveland Indians: 2.66 The Indians have the best road OPS in baseball with a mark of .820, but they only have a 26-34 record. 24. Oakland Athletics: 2.65 The Oakland lineup I saw on Tuesday against CC Sabathia and Yankees was one of the worst on paper that I've ever seen, so I was shocked to learn that the A's are second in runs scored since the break. 25. Washington Nationals: 2.62 The Nationals are one of seven teams with walks in at least 10% of their at bats. 26. Pittsburgh Pirates: 2.55 Take Garrett Jones. Multiply by eight and then the Pirates might have something. 27. Cincinnati Reds: 2.47 The Reds have the lowest team OPS in baseball and also are lowest in BABIP with a mark of .275. 28. Baltimore Orioles: 2.39 Matt Wieters came into the 2009 season as baseball's next great catcher, but Joe Mauer has put his spikes to the O's catcher and delayed that launch. Wieters is hitting better from the left (.736) than the right (.617), but he clearly has a long ways to go. 29. Kansas City Royals: 2.38 Billy Butler has quietly put up nice numbers, with an .841 OPS. 30. San Diego Padres: 2.36 Despite their cavernous ballpark, the Padres have thrown just two shutouts this season.
