I'm not sure exactly what info you are referring to, but if you mean the leverage index for each base/out state in the game, I have provided a link to the data.
This link comes with the caveat that this table was first published in 2006. Since run expectancy changes as the scoring environment changes, so does the leverage index. However, the leverage index should not be that much different than it is in the chart, and the relative importance of each situation remains the same.
If you're the away team and you're up by one run, with 0 outs and runners on 1st and 2nd in the 8th inning, the LI is 4.1. In the 9th inning with 0 outs and no runners on, the LI index is 2.9.
If you're the home team with the same situations, the LIs are 4.4 and 3.6, respectively.
Your best reliever should be pitching in that 8th inning situation, not being saved until the 9th inning.
