I think that in the modern game, and particularly on this team, pinch-running would be the smallest part of the role, by definition. The Twins only pinch-ran 43 times combined over 2019-2020, and they're generally not attempting steals either, so the relative difference between Cave and Broxton as pinch running options is minimal. The difference between their career batting lines, on the other hand, is worth about 7.9 Rbat prorated to 228 PA (which was the 2019 PA total for both of them). On defense, the career gap between Broxton and Cave, prorated to Broxton's 2019 innings, would be about 2.3 UZR or 6.6 DRS. Broxton turns 31 soon, though, which could be a negative factor in his defensive projection going forward? Cave's advantage in ZiPS projections, including defense, is about 8.2 runs (or 0.8 WAR) prorated to 228 PA.
