Late 2018 about .500
I think people vastly under-estimate how easy it is to 1-2 months with a .500 or worse record. A 10-game road trip, then a 6-game homestand against tough teams, followed by a 9-game road trip. Add in a few one-runs losses, and you can almost expect some negative (and positive) variance. There are formulas for this which I won't bore you with (since I don't know them), but if you flipped a coin 162 times, there is a decent chance it will come out with the same result 6-7 times in a row.
Just for fun, the LAD, from 7/4-9/6, went 22-32.
