It's not a perfect methodology, but yes, I think 5 IP allowing 1 ER is doing okay to well. The ghost runner ******** is not the pen's fault. Sure, they could have done better, but the starter let bup 3 ER in 5 IP. Are you saying that was better?
I did this study to show that the pen has done okay or better more often than not, even if you add the pen game as "worse" than the starters.
Granted, the starters go longer innings and don't come in with 1-2 outs, like some RP'ers do, but overall the pen has a better OPS against than the starters. This isn't me trying to say our starters are a bigger weakness than our pen, because I don't believe that. My point is to show that maybe the pen has not been as awful as some here seem to think it has been.
If going 5 IP allowing 1 ER, but 2 stupid ghost runners score is bad, then we can agree to disagree. The pen kept us in that game, and they blew it at the end by allowing a man placed on second to score, twice. How many runs would our starters have allowed, if a man was placed on 2B in some of their innings?
