I'm a Met fan, which creates an asymmetric skew in memory: the bad seems to stand out more than the good. As of 6/8/2021, they are in first place and I wanted to know, when was the last time this happened? More generically, for a given date, when was the last time they were in first? This notebook leverages baseball-reference.com to find the last time the Mets were in first place by date.
