OK, it's not a certainty, but Ort pitched well for Woo, they brought him up and he has done well in his small MLB sample. That's not usually the guy you DFA.
No one has ever relied completely on the eye test. Even old schoolers looked at batting averages, earned run averages, fielding percentages, whatever. We just have more refined (and in some cases trickier) stats now.
I guess I would need to see some meaningful statistical comparisons to other bullpens to really judge.
The "Team Relief Pitching" stats on B-R make our pen look terrible, but they're pretty wonky-looking stats.
The pen has the potential to be good by the end of the season, with additions like Schreiber and now Whitlock.
At the same time, so far it has ranged between adequate and awful.
