The Pythagorean Theorem of Baseball created by the Godfather of sabermetrics, Bill James, is a simple yet useful statistic for baseball teams. If you want the full breakdown of the statistic click here. If you want the TL;DR version (and you trust me) it's taking runs scored and runs allowed and creating an estimated winning percentage. Essentially, it's what a team's record should be based on runs scored and runs allowed.
The Astros are +99 runs prior to Wednesday's night game against he A's (+102 as of writing); the Rangers are -26 runs prior to Wednesday's night game against the Mariners (-31 as of writing).
The math is in the Astros favor (not the Rangers).
