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 final rankings through the Thursday, July 14th games: The rankings from last week are in parenthesizes 1. (1) New York Yankees - 4.32 New York is starting to struggle on the mound, but CC Sabathia is still their ace and a Cy Young contender. 2. (2) Boston Red Sox - 4.18 Adrian Gonzalez may have lost to Robinson Cano in the Home Run Derby, but he is still the best hitter in the AL. He leads the league with a .354 average and 77 RBIs. 3. (4) Philadelphia Phillies - 4.03 The Phillies could finish the season with three 20-game winners (Roy Halladay, Cole Hamels and Cliff Lee). 4. (5) Texas Rangers - 3.90 Texas has won eight straight, allowing them to take a 1.5 game lead over Los Angeles in the AL West heading into this weekend. 5.
