Well I would assume that the offense is also going to trend back towards their career numbers. I don't know if that will end up evening out but a couple things are not right with this team:
1) The starting pitching is mostly way overperforming expectations
2) The hitting has been atrocious for the last 5-6 weeks, performing way below their abilities based on career numbers
3) The bullpen is blowing games at a historic rate. They may be a bad bullpen, but as others have pointed out statistically they are not even a bottom 5 bullpen in the league. They are probably getting quite a bit unlucky there. If we only lost 4 games while having the lead in the 8th inning or later instead of 7, this team is 30-22 and 0.5 games out of first. That's Marte's HR being hit 1 foot shorter plus the Cubs not blowing an 8-0 lead vs SD plus Amaya getting a tag down correctly tonight. That's the difference between 27-25 and 30-22 right now.
While I'm extremely frustrated I still think this team is more likely than not to end up in the playoffs.
