This is correct.
A review of Mets no hitters suggests a couple of things:
As much as any dog may be able to have his day, better pitchers are going to get these things more frequently, and the Hall of Famers more frequently than that.
These things tend to happen more frequently in mid-summer, perhaps when a lineup is fatigued from the grind.
They also tend to happen the last week of the season, perhaps when a lineup has one foot in the offseason.
They also tend to happen in doubleheaders, perhaps when the line-up is checkered with subs and perhaps conserving their bullets.
