Trevor Williams and Stephen Nogosek rest the rest of the Met’s bullpen

Mets manager Buck Showalter credited Trevor Williams — who didn’t even field that day — for part of the team’s recent miracle win.

If the Mets whip up more magic Thursday, Williams and Stephen Nogosek could be in line for more backslaps.

On Wednesday night, the long man and the new man (Nogosek made his season debut) emerged from the bullpen and spared the Mets’ most valuable assists, going 6 ²/₃ together in a scoreless innings in an 8-3 loss to the Nationals in Washington .

Starter Tylor Megill had nothing for the Mets, allowing eight runs and recording just four outs before being pulled with a runner in the second inning. The Mets faced the prospect of a very long bullpen day that could consume Relieve after Relieve, the kind of loss that could result in a loss the next day.

Instead, first Williams and then Nogosek showed up, keeping the Mets close (which didn’t matter because their silent offense never closed the gap) and spared their bullpen pals.

“That was great,” Showalter said of Williams, who hadn’t served in a week, and Nogosek, who hadn’t served in 11 days. “I know there were some people in our bullpen who were quite happy about that and it puts us in a better light [Thursday’s] Game.

“Those are the things that good teams and teams with good depth are capable of. That is not easy.”

Williams allowed a single to Keibert Ruiz before seeding five of the next six Nationals. He went against Nelson Cruz in the fourth inning and then immediately obliterated him with a double-play ball from Yadiel Hernandez.

The right-hander pitched a perfect fifth inning before his pitch count (51) prompted Showalter to call out for Nogosek, who was called out earlier this week after a 1.69 ERA at Triple-A Syracuse.

The mustachioed Nogosek didn’t allow a hit in three innings, and only two Nationals reached on walks. None reached second base.

“I think we proved we have a chance if the game is still on,” said 27-year-old Nogosek, who last served with Syracuse on April 30 can win game.

Because of the work done by Williams and Nogosek, the Mets didn’t have to turn to Drew Smith or Joely Rodriguez, both of whom served Tuesday, and therefore both should be fresher Thursday.

The game recalled Williams’ efforts in a May 4 loss to the Braves, another start from Megill that went sideways when handed off to Adam Ottavino. But with Williams himself long busy cleaning up the mess, the Mets had a mostly filled bullpen for the following night – when Chasen Shreve, Adonis Medina and Edwin Diaz were fresh and combined for a five scoreless innings that allowed the Mets to to avoid a blowout. And that came in handy as they scored seven runs in the ninth to beat the Phillies.

If the Mets have to rely on a fresh bullpen in their Thursday matinee, Showalter will remember the two assists who will be sore.
