Cluster Luck

These cluster luck numbers started updating daily again on June 17th, 2016.

In baseball, teams have little control over the clustering of hits. Hence, we can use run creation formulas to estimate a team’s luck in clustering hits.

This table (updated daily) shows cluster luck for MLB teams in units of runs. A positive number implies good luck in all cases, e.g. positive cluster luck on defense implies a team allowed fewer runs than expected.
