“Listen, here’s the thing. If you can’t spot the sucker in the first half hour at the table, then you ARE the sucker.”

— Mike McDermott (Matt Damon), “Rounders.”

The week concluded with the Mets as the suckers.

Because this was supposed to be the week that the Mets got healthy (literally with Justin Verlander) and schedule-wise by playing among the sport’s weakest opponents in the Tigers and Rockies. Except the feeble club right now is not in the other dugout.

The Mets lost a series in Detroit and then one at home to Colorado, concluding with a 13-6 eyesore Sunday. After the Mets were beaten for the 11th time in 14 games, Francisco Lindor described a Mets conundrum of not hitting well when they receive good pitching, and not pitching well to complement strong hitting.

That is generally the formula for an also-ran, by the way. And through 35 games, the 17-18 Mets hardly appear the $370 million-ish goliath anticipated.

“Our pitching staff is really, really good,” Lindor said. “And our offense is really, really good, as well. We’ve got to put it together. Hopefully, sooner than later.”

They receive yet another favorable chance to make it “sooner” again this week by following an off-day Monday with seven games against the dreadful Reds and Nationals. They have, in theory, their best three available starters to begin the stretch in Max Scherzer, Verlander and Kodai Senga. But those three are metaphorical for the whole team, right now — looks great on paper, but is more worrisome in reality.

This would all feel better around the Mets if Scherzer and Verlander, in particular, pitch like the guys that the Mets made the highest per-annum paid players in history. And if the lineup finds upside consistency.

To the offense, Buck Showalter met with his most disappointing hitter, Starling Marte, before Sunday’s game. The Mets internally believe that Marte has hit in bad luck and over the long haul, he will be fine. Still, Showalter decided to give his right fielder a two-day reset — not in the lineup for the finale versus Colorado followed by the off-day. Showalter then moved Lindor up to second, inserted Jeff McNeil third in front of Alonso and hit Brett Baty fifth for the first time in his career.

The Mets manager would not commit to reinserting Marte at second and said he could even envision going Brandon Nimmo/McNeil 1-2 because the lefties do such a good job reaching base against lefties that Showalter is unafraid to bat them consecutively.

This assemblage worked in the first inning Sunday to counter the solo homer Joey Lucchesi surrendered in the top of the inning. Rockies starter Ryan Feltner did not throw a first-pitch strike to any of the eight hitters. He walked three. He gave up three singles, the last of which was by Luis Guillorme on Feltner’s 32nd pitch. That should have left two on with two out and the Mets ahead 3-1.

But Daniel Vogelbach moved off second to try to locate the ball. Kris Bryant threw behind him and Vogelbach was tagged out at second. It was inexcusable and Vogelbach admitted just how wrongheaded it was and that he beat himself up for the rest of the game.

I asked Showalter, especially in the aftermath of Brandon Nimmo’s brain-lock in trying and failing to steal in the ninth inning with the tying run at the plate on Thursday in Detroit, if he thought about pulling Vogelbach from the game as a message to the team. Showalter said Vogelbach was so distraught that it would be the wrong move and that the dugout was plainly aware it was a mistake without a grand gesture.

That play, though, changed the tenor of the game. The chance to knock out Feltner in the first or at least further build his pitch count vanished. Instead, by the time Lucchesi left after four innings it was 3-3. Jimmy Yacacabonis and Tommy Hunter teamed to allow seven fifth-inning runs. So that the Mets scored two more runs Sunday than in their four previous games combined was meaningless.

With so many pitching injuries, Showalter is trying to distribute innings so as to not blow out arms early in the season. But on a day like Sunday that meant four of the five pitchers he used (Lucchesi, Yacabonis, Jeff Brigham and Dominic Leone) were not even on the Opening Day roster and Hunter only was because of injuries to others like Edwin Diaz.

The roster at the moment is beset by fill-ins and the shortcomings of stars. It can turn this week if Marte returns productively to the lineup, Scherzer and Verlander deliver a couple of seven-inning gems and the Mets flex against two foes with a combined 28-40 record.

But we were saying similar stuff as last week began. And the Mets ended it at 17-18. It was a week of again being weak. A week in which the Mets looked around the table and they were the suckers.
