I decided to look into subject of Mets starts and what they told us -or did not tell us - about how the season would go.

I debated what a ‘good’ start was. I finally decided to designate any time the Mets played .600, (supposedly pennant-winning) ball in the first month, it was a good start and if they won 2/3 of their games it was a ‘hot’ start. I designated the hot starts in bold and the good starts in italics.
There have been six ‘hot’ starts: 1972, 1985, 1986, 1988, 2006 and 2016. The first five of those started with wins in the opener and wound up with a better record than the previous year, (all winning years at least 10 games over .500). 2016 was the outlier: starting with a loss and ending up with a worse record, but 12 games over .500.
There have been twelve other ‘good’ starts: 1971, 1973, 1976, 1984, 1991, 1992, 1999, 2002, 2007, 2010, 2015 and 2018. Ten of them opened with wins. Six resulted in improved records. Seven resulted in winning records.
I think what we’re looking for is a ‘hot’ start.
