It's not exactly lights out. They have the 7th best WHIP, 3rd best K/9, 4th best OPS against and 6th best ERA. Their biggest weakness is walks and Williamson has been one of the biggest culprits. He's got a 5+ ERA right now. It's not like he's the most important piece of the puzzle. I think our vision of a "lights out" bullpen may be skewed by the bullpens we've had in the past. This bullpen is much better than previous iterations, and Williamson had a very good ERA until last night's unfortunately unpleasantness. (It was somewhere around 2.00)
