Well, good for Harper, I guess, but the Phillies -- a team so bad that they fired their manager midseason -- are the NL champs, with a whopping 87-75 record, 6th best in the NL.
In an era with teams dominating the regular season, the NL champions for the past 3 seasons have been:
2019: Washington Nationals (93-69), won World Series
2021: Atlanta Braves (88-74), won World Series
2022: Philadelphia Phillies (would have missed playoffs every other year in MLB, 87-75), about to play World Series
The '19 Nationals and '22 Phillies were both failteams in the first half of these years.
