In the last 7 years the Astros lost to eventual World Series champions 4/5 times.

2017 – Won

2018 – Lost to Red Sox -> won World series

2019 – Lost to Nationals -> won World Series

2020 – Lost to Rays -> lost World Series

2021 – Lost to Braves -> won World Series

2022 – Won

2023 – Lost to Rangers -> won World Series

​

This pretty much means, we're literally the best team in the league because we only lost to the eventual WS champion.
