The positive sentiments expressed by Francisco Lindor before Wednesday’s game were believable. The explanations offered by James McCann afterward were sensible.

And the in-between disconnect was all too familiar for the new-look Mets, who continued conjuring up the ghosts of the franchise’s past in a 1-0 loss to the Red Sox.

The most recognizable ghoulish spirit presented itself in the Mets wasting another outstanding effort from Jacob deGrom, who has been so stupendously good that allowing one run on three hits and a walk and recording nine strikeouts over six innings qualifies as a subpar start.

DeGrom looked as if he might be feeling the effects of his most recent start — a 15-strikeout shutout of the Nationals last Friday — as he atypically battled his mechanics and was battled deep into counts by the Red Sox, who fouled off 27 pitches.

Of course, when a guy has an off-day and his ERA rises to 0.51 and he still has more hits as a batter (six) than walks as a pitcher (four)…

“You didn’t know, quote unquote, he didn’t have his best stuff tonight,” McCann said. “But if Jake deGrom doesn’t have good stuff and goes six innings, one run, nine ‘punchies,’ he must be pretty darn good.”

Another pretty darn good effort yielded yet another bagel in the win department. The loss marked the 33rd time since 2014 — when he debuted by allowing one run over seven innings and taking the loss against the Yankees, talk about foreshadowing — that deGrom has gone at least six innings, given up one run or less and not earned the win.

Such efforts were supposed to be regularly rewarded following a transformative off-season by the Mets under new owner Steve Cohen. Instead of trying to buy legitimacy by acquiring former superstars long past their peak, the Mets are now augmenting their promising young core with fellow ascending talents.

But while it’s still early, nights like Wednesday are far too reminiscent of early-season nights the Mets endured on so many early-season nights the last three decades, when the calendar and the track records of the slumping players warranted extending them the benefit of the doubt.

Except, of course, the likes of Roberto Alomar, Bobby Bonilla, Jeromy Burnitz, Mike Cameron, Roger Cedeno, Vince Coleman, Eddie Murray and Mo Vaughn either never met expectations or only did so long past the point where seasons and tenures could have been saved. The strangely supportive boos from the Shea Stadium crowds eventually turned more sinister, ruining the relationship before it could even really begin.

And the boos sounded more impatient Wednesday night, when Lindor, who signed a 10-year extension before playing a regular season game with the Mets, and impending free agent Michael Conforto each heard it from the pandemic-era sellout crowd of 8,051 after they sandwiched strikeouts around Pete Alonso’s single. The hitless efforts by Lindor and Conforto dropped their batting averages to .203 and .217 and their respective OPS+ of 67 and 90 — well below the league average.

Lindor and Conforto should be all right, which means the Mets will probably be all right despite ranking last in the majors with 57 runs — 18 fewer than the Nationals and Tigers. Conforto’s already well-established as a middle-of-the-order presence mature enough to handle some boos and catcalls. Lindor is new to the Big Apple, but he’s far younger than any of his big-name predecessors and already further down a Hall of Fame path upon his arrival in Queens than everyone except Alomar and Murray.

And if every (admittedly distant) press conference interaction with Lindor is any indication, he’s much better equipped to handle the New York fishbowl than any of his predecessors except Vaughn. He was quick with smiles Wednesday, when he made a point to refer to every questioner by his or her name, and said he understood the impatient nature of Mets fans.

“I get it,” Lindor said. “It’s part of the job. People expect results and they’re booing because there aren’t results. I just hope they cheer and jump on the field when I start hitting home runs and start helping the team on a daily basis lot more than I’m doing right now.”

While it’d probably be a bad idea to jump on the field, the Mets should begin providing catharsis to impatient fans sooner than later. Eventually, Lindor and Conforto will hit like they are capable and the Mets will look something like they envisioned in the winter. Alonso already has five homers. The universal designated hitter can’t arrive fast enough for J.D. Davis, but he’s not going anywhere as long as he’s posting an OPS north of 1.000. Imagine how bleak things would look if the Mets replaced All-Star caliber leadoff hitter Brandon Nimmo with George Springer, who didn’t debut for the Blue Jays until Wednesday due to oblique and quad injuries. Dominic Smith is the unluckiest hitter in baseball, per StatCast.

“Not the start that you’re looking for,” McCann said. “But at the end of the day, it’s still very early in the season. The thing that I’m trying to preach to each and every guy in the locker room is if you go through a stretch like we’re going through in the middle of July and August, you don’t look up at that Jumbotron and look at the numbers and say that’s not where we want to be. But (when) it happens at the beginning of the season when there’s not a lot of numbers, it looks worse than it what may look like in July or August.”

Until, as the Mets of many years prior can confirm, it becomes July or August.
