The Opsera is a statistic RealGM's Chris Reina created in order to objectively rank teams by how well they hit (OPS) and pitch (ERA). In order to determine a team's Opsera, we 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. Below are the final rankings through Wednesday, June 22nd’s games: Last week’s ranking is in parenthesizes 1. (1) New York Yankees – 4.31 The Yankees have lost eight of nine to the Red Sox this season, but they were briefly in first place (by percentage points) on Wednesday afternoon following Boston’s loss and prior to their loss in Cincinnati. T2. (2) Philadelphia Phillies – 4.03 The Phillies are still in the middle of the pack in most offensive categories, but they have the third-best run differential in baseball. Thank you, pitching. -- (3) Boston Red Sox – 4.03 Boston is 8-1 against New York, but just 36-29 against the rest of baseball. Can they schedule the Yankees more often in 2012? 4. (4) Atlanta Braves – 3.90 5. (8) Texas Rangers – 3.59 The Rangers have lost six of their last 10 games. It’s a good thing that the Mariners, Angels and Athletics haven’t been consistent this season. T6. (6) St. Louis Cardinals – 3.51 -- (7) Arizona Diamondbacks – 3.51 How much of a shock would it be if the Diamondbacks edged the Giants and Rockies in the National League West? 8. (5) Milwaukee Brewers – 3.50 The Brewers need Shaun Marcum’s hip to be a non-issue and it’s just not cooperating. 9. (9) Los Angeles Angels – 3.46 10. (13) Tampa Bay Rays – 3.37 11. (T10) Colorado Rockies – 3.36 T12. (T10) San Francisco Giants – 3.30 -- (12) Detroit Tigers – 3.30 14. (19) Oakland Athletics – 3.29 T15. (T15) Washington Nationals – 3.25 -- (22) Cleveland Indians – 3.25 17. (14) Cincinnati Reds – 3.24 Chris Heisley hit three home runs against the Yankees on Wednesday night. He entered the game with 11 homers in his previous 161 major league games. 18. (18) Chicago White Sox – 3.19 19. (T15) Toronto Blue Jays – 3.13 20. (20) New York Mets – 3.11 Am I the only one that doesn’t buy the belief that the Mets can contend for the Wild Card? They entered Thursday’s action six games back of the Braves with a number of better teams in-between. 21. (24) Seattle Mariners – 3.10 22. (T15) Pittsburgh Pirates – 3.07 23. (21) San Diego Padres – 3.03 24. (23) Florida Marlins – 2.99 It’s almost July and Hanley Ramirez is still playing like a below-average shortstop. It’s just about to the point that it’s no longer just a slump. 25. (25) Baltimore Orioles – 2.88 26. (26) Los Angeles Dodgers – 2.84 What could Mark Cuban do for this franchise? At the very least he’d be able to pay the bills without help. 27. (27) Kansas City Royals – 2.62 28. (29) Houston Astros – 2.45 29. (30) Minnesota Twins – 2.44 A recent tear has the Twins out of the last spot in our rankings for the first time this season. Next week? Jumping ahead of the Astros is a very real possibility. 30. (28) Chicago Cubs – 2.38

Below are the final rankings through Thursday, June 16th’s games: Last week’s ranking is in parenthesizes 1. (2) New York Yankees – 4.42 The Yankees have baseball's third-best record, but they hold a significant lead in our rankings thanks to their supreme hitting and surprising pitching. 2. (5) Philadelphia Phillies – 3.97 Philadelphia has won seven straight as their hitting as started to come around. 3. (7) Boston Red Sox – 3.92 The Red Sox are hunting for the top spot in our rankings after occupying the 21st spot a little more than a month ago. 4. (4) Atlanta Braves – 3.84 5. (6) Milwaukee Brewers – 3.74 6. (1) St. Louis Cardinals – 3.64 A six-game losing streak has the Cardinals sliding down five spots to sixth, the lowest they've been in our rankings all season. 7. (10) Arizona Diamondbacks – 3.55 8. (3) Texas Rangers – 3.48 9. (9) Los Angeles Angels – 3.46 T10. (11) San Francisco Giants – 3.45 -- (15) Colorado Rockies – 3.45 12. (17) Detroit Tigers – 3.41 The Tigers are in first place in the AL Central, having survived Cleveland's early surge. Their hitting is better than their pitching, but both have been strong as of late. 13. (T13) Tampa Bay Rays – 3.29 14. (21) Cincinnati Reds – 3.22 The Reds have won four of five, but have a rough interleague slate coming up with the Blue Jays, Yankees, Orioles, Rays and Indians on the schedule. T15. (8) Toronto Blue Jays – 3.20 With the Yankees and Red Sox on the upswing, the Rays are falling behind in the AL East. A four-game series against New York right before the All-Star break could make-or-break their season. -- (16) Pittsburgh Pirates – 3.20 -- (23) Washington Nationals – 3.20 18. (T18) Chicago White Sox – 3.18 19. (T18) Oakland Athletics – 3.15 20. (24) New York Mets – 3.12 21. (20) San Diego Padres – 3.11 22. (12) Cleveland Indians – 3.10 As expected, the Indians have officially returned to Earth. They have lost eleven of their last fourteen games and they have tough NL opponents coming up. 23. (T13) Florida Marlins – 3.04 24. (22) Seattle Mariners – 2.98 25. (26) Baltimore Orioles – 2.83 26. (25) Los Angeles Dodgers – 2.80 27. (27) Kansas City Royals – 2.65 28. (28) Chicago Cubs – 2.38 29. (29) Houston Astros – 2.37 30. (30) Minnesota Twins – 2.31 The Twins still have one of baseball's worst records and they haven't gotten out of our last spot all season, but they are showing signs. They have won eleven of thirteen, Joe Mauer will be in the lineup on Friday and they added 25 points to their Opsera total this past week.

Below are the final rankings through Thursday, June 9th's games: Last week's ranking is in parenthesizes 1. (2) St. Louis Cardinals - 4.08 The Cardinals won five of six to surpass the Yankees and retake the top spot in our rankings. They outscored opponents by a score of 31-17 with their lone loss coming against the Astros. 2. (1) New York Yankees - 4.06 Yet another three-game sweep at the hands of the Red Sox at Yankee Stadium dropped New York from first. Upcoming series against the Indians and Rangers are rather vital to the Bombers. 3. (4) Texas Rangers - 3.93 4. (3) Atlanta Braves - 3.90 5. (5) Philadelphia Phillies - 3.70 6. (6) Milwaukee Brewers - 3.68 7. (T11) Boston Red Sox - 3.66 Winners of six-straight, including those three against the rival Yankees, have the Red Sox higher than ever in our rankings. The poor start they endured officially seems like ancient news. 8. (9) Toronto Blue Jays - 3.59 9. (7) Los Angeles Angels - 3.58 10. (13) Arizona Diamondbacks - 3.51 11. (15) San Francisco Giants - 3.48 12. (8) Cleveland Indians - 3.42 Losers of six of seven, the Indians are playing like the team we thought they'd be heading into the 2011 season. They can stick their foot back in the American League door if they can defeat the Yankees in New York this weekend. T13. (T11) Florida Marlins - 3.34 -- (14) Tampa Bay Rays - 3.34 15. (16) Colorado Rockies - 3.28 16. (17) Pittsburgh Pirates - 3.24 17. (23) Detroit Tigers - 3.20 The Tigers are surging thanks in large part of the bat of Miguel Cabrera. The first baseman is hitting .317/.435/.573 with 13 home runs and 45 RBI. The slugger is hitting .355/.459/.677 with three home runs and eight RBI this month. T18. (10) Oakland Athletics - 3.18 Injuries to the starting rotation have lowered Oakland's pitching numbers. The once elite ERA (3.33) has dropped to fifth and opposing pitchers are hitting .251, which ranks 16th. That's not hard to believe with Brett Anderson, Brandon McCarthy, Tyson Ross and Dallas Braden hurting. -- (T20) Chicago White Sox - 3.18 20. (22) San Diego Padres - 3.14 21. (19) Cincinnati Reds - 3.10 22. (18) Seattle Mariners - 2.98 23. (T20) Washington Nationals - 2.93 24. (25) New York Mets - 2.92 25. (24) Los Angeles Dodgers - 2.85 26. (27) Baltimore Orioles - 2.71 27. (26) Kansas City Royals - 2.48 The Royals have recalled their top-two hitting prospects in Eric Hosmer and Mike Moustakas, but their issue has been pitching. They rank next-to-last in ERA, quality starts and WHIP and last in batting average against. 28. (28) Chicago Cubs - 2.42 29. (29) Houston Astros - 2.41 30. (30) Minnesota Twins - 2.06

(1) St. Louis Cardinals – 4.01 St. Louis has allowed 47 runs in their last six games (four losses). 3. (T3) Atlanta Braves – 3.96 4. (8) Texas Rangers – 3.88 5. (5) Philadelphia Phillies – 3.76 6. (11) Milwaukee Brewers – 3.71 Milwaukee’s pitching staff has surrendered four or fewer runs in fourteen of their last seventeen games. 7. (7) Los Angeles Angels – 3.69 8. (T3) Cleveland Indians – 3.64 The Indians have hit a rough patch, losing six of their last nine games. Still, they hold a 4 ½ game lead over the Tigers heading into Friday night’s action. 9. (12) Toronto Blue Jays – 3.63 10. (10) Oakland Athletics – 3.58 T11. (6) Florida Marlins – 3.51 -- (9) Boston Red Sox – 3.51 After peaking last week, the Red Sox have lost four straight.

(18) Pittsburgh Pirates – 3.18 18. (19) Seattle Mariners – 3.04 19. (21) Cincinnati Reds – 3.03 Dusty Baker’s pitching staff has been banged up, but better production would launch the Reds up this list. Only the Cardinals and Yankees have scored more runs this season, but only four teams have higher team ERAs. T20. (17) Chicago White Sox – 3.01 -- (26) Washington Nationals – 3.01 22.
