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.
