WSJ’s Carl Bialik, Leverage Index, and A-Rod

Here’s the snippet:

His career OPS in high-leverage situations is .975. In medium-leverage, it’s .960. And in low-leverage, it’s .972. That’s consistent with the American League as a whole during his career, when each year batters in high-leverage situations hit somewhere between 1% worse and 6% better than they did in low-leverage situations....  In 2004, he hit 19% better in high-leverage situations than in low-leverage ones. In 2005 and 2006, he hit 17% worse. Last year, he hit 15% better. And this year, he’d hit 32% worse, through Monday.
