Baseball Base Runs Calculator

Calculate Base Runs (BsR) - an advanced run estimator that models the run-scoring process

About Base Runs

Base Runs (BsR) was developed by David Smyth as an improvement over Runs Created. The formula models how runs are actually scored: BsR = (Baserunners x Advancement) / (Advancement + Outs) + Home Runs. This approach better handles extreme cases and is more theoretically sound than simpler run estimators.
