I happen to have just finished reading the original post on TheAthletic.com and while the report appears fairly definitive and damning, the author didn’t bother to discuss results.
The ‘when’ and ‘where’ parts of this involved home games during 2017... a year in which the Astros were 15 games above .500 at home, but 25 games over .500 when on the road... and this scheme could not be employed during road games.
Additionally, as a team, they hit .279 at home and .284 on the road in 2017. There were also a few road games in which they would have been in National League (non-DH) parks, which might have dragged the team avg. down slightly.
So if this was really happening, it kinda had a reverse impact on Houston... they played better when they didn’t use it!
This year the Astos record was an insane 60–21 at home (possibly a record) and a pedestrian 47–34 away.
