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. The Cardinals are first this week and since their OPS is .840 and their ERA is 2.86, 8.40-2.86 equals 5.54. 1. St. Louis Cardinals: 5.54 There has been no letup from Ryan Ludwick, who is hitting for an OPS of 1.228, which goes well with Albert Pujols and their starters who are putting up a collective 2.20 ERA. 2. Chicago White Sox: 5.45 While Carlos Quentin has looked like his 2008 self (1.055 OPS), Alexei Ramirez has started slow with a .377 OPS. 3. Atlanta Braves: 4.90 Six members of the Braves with at lest 14 at bats (Kelly Johnson, Jordan Schafer, Brian McCann, Chipper Jones, Matt Diaz and Yunel Escobar) have an OPS of 1.084 or better. 4. San Diego Padres: 4.80 Chris Young is back with a 1.38 ERA and 12 strikeouts in his first 13 innings of work. 5. Tampa Bay Rays: 4.67 Evan Longoria has five homers in his first 27 at bats of 2009. 6. Florida Marlins: 4.53 Emilio Bonifacio has been a true difference maker in Florida's first week, hitting for an OPS of 1.231 with four steals and nine runs scored. 7. Detroit Tigers: 4.35 Miguel Cabrera and Brandon Inge have been monsters, combining for seven homers and have a 1.546 and 1.318 OPS respectively. 8. Chicago Cubs: 4.28 Can Kosuke Fukudome keep this up? The much-maligned second year outfielder is hitting .409/.480/.818 with two homers. 9. Los Angeles Angels: 4.11 The Angels completed an impossible week with a 3-3 record. 10. Toronto Blue Jays: 3.98 Roy Halladay has a relatively modest 3.86 ERA and 5.79 K/9 rate, but he is 2-0 already. 11. New York Mets: 3.78 Mets' pitchers have combined to strike out 55 batters in 51.2 innings of work. 12. Seattle Mariners: 3.77 Even with ERAs over 10.00 for Brandon Morrow and Carlos Silva, the Mariners have a team ERA of 2.92. 13. Pittsburgh Pirates: 3.55 Nyjer Morgan has been a promising surprise, with an OPS of 1.003. 14. Los Angeles Dodgers: 3.54 Hiroki Kuroda, Eric Stults and Clayton Kershaw each have an ERA under 2.00. 15. New York Yankees: 3.48 Nick Swisher might be the Yankees' best offseason acquisition thus far, as he's hitting .471/.550/1.118 with two homers, three doubles and one triple. 16. Colorado Rockies: 3.45 Ubaldo Jimenez, Franklin Morales and Jason Marquis have been excellent, with ERAs of 0.00, 1.50 and 2.57 respectively. 17. Kansas City Royals: 2.69 The Royals are looking a little like the 2008 Reds in terms of excellent strikeout rates, especially with the way bullpen arms Joakim Soria, Juan Cruz, Kyle Farnsworth and Robinson Tejada are capable of mowing batters down. 18. Oakland Athletics: 2.61 Matt Holliday is just 4-for-17 with one extra base hit. 19. Boston Red Sox: 2.51 While Jason Bay, Kevin Youkilis and Jason Varitek are starting fast, each with an OPS over 1.000, Dustin Pedroia, Mike Lowell, J.D. Drew, David Ortiz, Jacoby Ellsbury and especially Jed Lowrie have struggled. 20. Baltimore Orioles: 2.44 Despite the low strikeout rate (3.75), Jeremy Guthrie has a 2.25 ERA and two wins. 21. Texas Rangers: 2.03 After sweeping Cleveland to start the season, the Rangers were swept by the Tigers in which they were outscored 25-9. 22. San Francisco Giants: 1.95 Even with Tim Lincecum's ERA at 7.56, Barry Zito still comes in behind him with a mark of 9.00, but at least Jonathan Sanchez is even worst with a mark of 9.64. 23. Cincinnati Reds: 1.52 After a rough Spring Training, Aaron Harang has a 0.64 ERA in his first 14 innings. 24. Minnesota Twins: 1.35 Offense has been problematic for the Twins, who don't have a single hitter with an OPS over .830. 25. Philadelphia Phillies: 1.31 WBC fatigue? Jimmy Rollins is hitting for an OPS of .274. 26. Milwaukee Brewers: 0.85 With his performance on the mound and at the plate, Yovani Gallardo is Milwaukee's early CC Sabathia for 2009. 27. Houston Astros: 0.83 While Hunter Pence is off to a 1.012 OPS start, Lance Berkman, Carlos Lee and Miguel Tejada have struggled. 28. Arizona Diamondbacks: 0.67 The D-Backs have been outscored by 2.5 runs per game. 29. Cleveland Indians: -0.73 If you would have said the Indians would have Travis Hafner and Victor Martinez both hitting an OPS over 1.000, along with Shin-Soo Choo continuing his 2008, you would expect them to be 5-1 instead of 1-5. 30. Washington Nationals: -0.96 The Nationals still hare horrible, but at least Adam Dunn has been a productive pickup, as he's hitting 1.127.
