I couldn't put my hands on Inherited Runners with a quick search. But situational numbers exist. Baseball-reference.com has splits for everyone, and you can see Pressly's here: https://www.baseball-reference.com/players/split.fcgi?id=pressry01&year=2017&t=p I like opponents' OPS for relievers more than things like ERA. Pressly's for the season is .721, which would seem OK - league-average or thereabout. However, his baserunner splits are astounding. Bases empty, opponents manage only .490 against him, built on a .165 batting average. However if anyone is on base, opponents OPS a Ruthian 1.017 against him. You are definitely onto something there, this year. Still, splitting the stats for relievers mean dealing with small sample sizes. In years past, this pattern hasn't been in evidence for Pressly. Indeed in 2014, it was exactly the opposite - every batter became Mike Trout when the bases were empty, batters turned into Stuart Turner once someone else got on base. So I don't really know for sure what to make of it all. Baseball's a funny game. But I sure wouldn't put Pressly at the top of my list of options when the bases are occupied, until he gave me new reason to trust him better.
