The Astros just ended a memorable run, a couple series before the ultimate prize. They snuck into the playoffs by winning the 2nd Wild Card by one game, finishing 86-76, the worst record for 2nd Wild Card since the new format was introduced. Almost no one saw this coming, and it would be easy to say they overachieved, and will need to get significantly better to maintain success.
Is this true though? Looking deeper at the underlying stats paints a much different picture, and bodes well for the future.
Just looking at Pythagorean Record, which takes basic runs scored and runs allowed to determine expected won loss records, the Astros should have finished 93-69.
