Here's how the AL playoff teams rank by Pythagorean W-L, and how many games they have over or underplayed that mark.
Astros 104-50 -7
Red Sox 99-56 +6
Yankees 93-61 +2
Guardians 93-61 -7
As 91-64 +3
Not that it means much at this point, but the Red Sox have been a bit lucky, while the Astros and the Guardians a bit unlucky.
