For the purpose of measuring relative strengths in the bullpen, I have selected four relievers to represent each team, guessing at which four will pitch the highest-leverage innings. Using the same method I used in the post on rotations, here are the respective quartets:
The Tigers' problem is that no lead looks safe with Joe Nathan as the closer. He has been booed in Florida, which is not going to help matters, either. However, taking the Tigers' bullpen as a unit, the righty set-up men, Al Alburquerque and Joakim Soria, look a bit more solid than their equivalents on the Cleveland Indians, the Royals and the Minnesota Twins. It looks as if the Tigers' fate is going to depend a lot on how many left-handed hitters they are going to face in high-leverage situations.
