The New York Mets have the best record in baseball. The Mets, whose biggest free-agent signing was a player from last year’s 70-win team, are 10-1 on the season. The Mets, whose two biggest pitching acquisitions have compiled 2.1 totals innings so far this season, are 3.5 games up in their division and have already swept presumptive favorite Washington Nationals.
As Jeff Sullivan detailed earlier this week, no team has improved its playoff odds since the season began as much as the Mets. Winning 10 out of 11 games is certainly a surprising way to start. It would be surprising for any team — even the Astros have around just a 3% chance of winning 10 out of 11 games — but it isn’t all that surprising that the Mets are good right now. They should expect life to get tougher as the season goes on.
To provide a sense of how unlikely the Mets were to start 10-1, the graph below shows the odds of each win total from zero to 11 based on the assumption of the Mets as an 85-win team.

Eighty-seven times out of 100, the Mets end up with four to eight wins — with a one-in-120 shot at winning 10 games. I should also note that their schedule has been roughly neutral thus far, with the series against the Nationals balanced out by games against the Marlins. As for this version of the Mets, it might seem improbable after last year’s difficulties, but the Mets probably weren’t as bad in 2017 as their record ultimately suggested.
Consider a brief list of the factors that contributed to the Mets’ woes last year:
- A mere 30.1 innings from ace Noah Syndergaard, who was projected for 5.6 WAR.
- A mere 81 games from Yoenis Cespedes, who was projected for around three wins.
- Combined replacement-level production from the bottom of the rotation. Chris Flexen, Robert Gsellman, Matt Harvey, Steven Matz, Tommy Milone, Tyler Pill, Zack Wheeler, and Adam Wilk made 88 starts, put up a 6.12 ERA, and recorded -0.2 WAR.
- Despite good performances from Addison Reed and Jerry Blevins, one of the worst bullpens in baseball.
- Almost no production from the third-base position, which produced a 93 wRC+ and 0.6 WAR.
There are other factors, but those appear to be the main issues that caused the Mets to lose more than 90 games. We will look at what has changed or not changed in a bit, but first let’s consider that the Mets’ 70 wins might not have been a good representation of their talent level even with the issues above. The graph below shows team WAR in 2017 along with team wins from last year.

Notice first the very clear linear relationship. The more WAR a team accumulates, the more wins they get. If someone doesn’t believe in WAR, they are ignoring a very close relationship between WAR and wins. The relationship isn’t perfect, of course. Some teams (the ones above the trend line) outperformed their WAR totals, while others (below the line) underperformed them. Looking at the distance from the line can provide a sense of how much a team over- or under-achieved. The Mets show up as one of the biggest underachievers. The five teams with the closest WAR totals to the Mets — the Angels, Mariners, Marlins, Rockies, and Twins — won an average of 81 games last year, with the Marlins’ 77 wins representing the lowest figure. Even with the poor performances in the rotation and the bullpen, the Mets should have been better last season.
