Huh?
They won more games than they were expected to and they also scored more runs than they were expected to(from Baseruns).
How is that using the best of both worlds?
Both statements are true, they both exceeded their pythag, which is based on RS/RA and also scored more runs than their offense would indicate.
Since neither of those have been shown to be sustainable they are not likely to continue into next season.
This article is from Sept 20.
Being lazy I'll extrapolate it over 162.
The 2023 Orioles scored 807 runs, they should have scored 775 runs. (It's off a bit since I'm being lazy and the O's actual runs scored were down from that point in the season).
If you plug 775 RS and 678 RA into the system you get a .556 WP, or 90 wins. That's the same record as the Rangers and one up on the Blue Jays, two up on the Mariners. That may or may not have been a WC team.
No idea why I just wasted five minutes doing that when I know you won't pay any attention to it.
Maybe someone else will appreciate it.
Edit- Now I see Frobby addressed this as I was working on it and had an easier answer. Oh well.
