STARTERS: BPV none on/runners on, 2019
Jun 8 2019
Our original research in 2013 confirmed that there are significant skill differences among pitchers when throwing with the bases empty compared to with runners on base.
This trend continues to hold true. Pitchers have produced a near-100 BPV in each of the last five seasons with the bases empty, compared to a mediocre sub-70 BPV when pitching with runners on base.
We can visualize this impact by comparing the skills of pitchers in those two situations over the last seven seasons with the average overall skills posted by starting pitchers during the same period:
Here is an updated analysis with stats and skills for the none on/runners on split over the last seven seasons:
