It starts with 'modern baseball" - pull your 3-time Cy Young award winner who has shut out the other team for 7 innings because, well, you wouldn't want to leave him in one inning too long. Then the guy you bring in to pitch the 8th inning gives up three hits, a walk and two earned runs.
We get down to our last strike in the ninth. Canha works an 0-2 count to 3-2, then hits what should have bene a game-ending grounder to the greatest fielding third basemen of our time who can't get the ball out of his glove in time and airmails the throw to first, allowing Escobar to score from second. McNeill doubles, putting runners on second and third. Then Dom Smith, who's been on the interstate, hits a line drive down the right field line that Goldschmidt makes what should have been a game-ending play on. But the pitcher gets there late and Dom dives for the plate, (which works for once). The pitcher then makes goof #2, not seeing until it was too late that McNeill was sliding across home plate with the go-ahead run. They bring in another guy whose first pitch winds up in the right field stands, courtesy of Brandon Nimmo. Suddenly the Mets have a 5-2 lead. In the 9th, Diaz continues to look like the guy we traded for four years ago and shuts the Cardinals down.
Another game of the sort we used to lose that we are winning this year. It's fine to have sayings like "It ain't over under it's over" and "You gotta believe". But when you have a comeback like this, you actually do believe. This team will expect to win every game this season. Sometimes they'll be wrong, but they will continue to expect it anyway. That's half the battle.
13-5, baby!
(Note: the '86 Mets were 13-3 after April and had 20 wins when they got their 5th loss. the 1988 Mets were 15-6 after April and had 11 wins when they had 5 losses. Those are the gold standards for Mets starts.)
