So as I write this, the Mets will end the so-called first half of the year either 14 games under .500 or 16 games deep (and maybe if we get rained out, 15). Any one is a farce and speaks to a truly dreadful year in which we learned that young players don’t always perform well and older guys don’t stay healthy, first-year managers make lots of mistakes, and the destabilizing effect of a meddlesome and accountability-free front office in the throes of crisis, completely unprepared for a succession.

Actually we learned every one of those things before, but thanks for the reminder, Mets.

Now here’s the punchline: I’d been slow to catch up to this week’s comings and goings in part because I was too busy going to Mets games.

Last Sunday’s nice weather tempted us to head out as a family only to see a near no-hitter. My regular Tuesday night game with my brother was nearly a repeat but notable because I did to recognize the day’s starting pitcher when I saw it listed and I’m a guy who makes it his business to be on top of that kind of stuff. Then on Friday it was the annual outing with scattered former work colleagues. That one turned out nice, with a big assist from an exceedingly sloppy Washington club.

So meet Drew Gagnon. He nearly got five innings in, had a little bit of bad luck, but when it was over took an 11.57 ERA back to Las Vegas where he’s got to be wondering whether he’ll ever a shot at big-leaguedom again. Gagnon was issued No. 47, which we last saw on Hansel Robles.

Matt den Dekker is also back in action. I liked seeing this addition as the guy could always go and get in center field, and that’s what he’s been doing. He’s wearing 23 now, and not the 6 he used to in his first go-round, since 6 remains tragically bogarted by hitting coach Pat Roessler, and the No. 16 he was wearing in Spring Training had been relegated to since-demoted outfielder Kevin Kaczmarski. 23 belonged last to Adrian Gonzalez.

The Mets are racing toward a record number of players on the roster in a single year — an active trade deadline could nearly assure it — but thus far have only re-issued numbers three times (23, 47 and 62), believe it or not. That’s in part because of their willingness to just keep going higher. That’s one thing to watch as the SHaMs (Second-HAlf Mets) get underway.
