It wasn’t too long ago that the offense was picking up the slack for the bullpen. This is how things tend to work over the course of the season. For some stretches the offense picks up the slack for the pitching and sometimes it’s the other way around.
At the end of the season, if they’re 3rd in offensive fWar, 11th in bullpen fWar, 10th in fielding fWar, and are able to improve upon their current position of 18th in SP fWar by virtue of Shota returning and/or a trade or two, they’ll be just fine.
