The majority of players in the league end up with Clutch scores between 1 and -1, with zero being neutral, positive scores being “clutch”, and negative scores being “choke”. Only a few players each year are lucky enough (or unlucky enough) to have extreme Clutch scores.

High leverage situations correspond to exciting moments for the baseball fan. Leverage Index (LI) was developed by Tom Tango and measures the amount of swing in the possible change in win probability indexed against an average value of 1.00. So relievers who come into games in various situations create a composite score around 1.00. Leverage Index is essentially a measure of how critical a particular situation is. To calculate it, you are measuring the swing of the possible change in win expectancy. You take the current base-out state, inning, and score and you find the possible changes in Win Expectancy that could occur during this particular plate appearance. Leverage values below one represent situations that are less important than the start of a game (such as mopup innings in a blowout). Leverage values above one represent situations with more importance (such as a closer protecting a one-run lead with bases loaded in the 9th inning).

The highest leverage (boLI = 2.667) situation comes with two outs and the bases loaded. This is a do or die situation with possible run values ranging from 0 (an out) to 4.104 (grand slam + expected runs from future batters in the inning). The lowest leverage (boLI=.407) situation comes with 2 out and the bases empty.
