Not even Colorado’s Austin Gomber and his 7.57 ERA could get the Mets going, as their struggles continued in a 5-2 loss at Citi Field on Saturday.

It was the Mets’ fourth loss in five games and they’ve also lost 10 of 13 to drop back to .500.

And unlike on Friday, when Kodai Senga and the bullpen held the Rockies scoreless, the Mets’ lack of pitching depth was on display, as Tylor Megill and Stephen Nogosek weren’t as nearly as good.

But the reality is, the Mets had scored two runs in their previous three games and as Buck Showalter noted following Friday’s win, teams won’t win much with that formula — regardless of how good their pitching is.

One of the main issues is a lack of clutch hitting, with the Mets going hitless again with runners in scoring position on Saturday. They’re 0-for-19 in those situations over the last four games — three of them losses.

“We haven’t done it collectively and haven’t been as consistent,’’ Francisco Lindor said. “We will be consistent. We’ll fight the fight.”

Gomber entered with an ugly ERA, but had allowed just one run over 11 innings in his previous two starts and he proved to be more effective than Megill, who remains in the rotation with Carlos Carrasco and Jose Quintana on the IL.

With a chance to get back in the game in the bottom of the eighth after a two-out single by Lindor was followed by a Pete Alonso walk, Jeff McNeil — pinch-hitting for Tommy Pham — struck out to keep it a three-run game.

And in the ninth, they resorted to pinch-hitting Luis Guillorme for Eduardo Escobar, which also didn’t work out.

With no margin for error, Megill couldn’t overcome the lack of help from the offense. His first seven pitches were balls until a 3-0 strike to Randal Grichuk was greeted with mock cheers.

He also hit Kris Bryant with a pitch in the top of the first before Elias Diaz singled in Charlie Blackmon with the game’s first run.

The Mets tied the game in the bottom of the inning thanks to a soft infield hit by Brandon Nimmo, a double by Lindor that sent Nimmo to third and a run-scoring groundout by Alonso.

Lindor’s double was the Mets’ only extra-base hit of the day.

Colorado went ahead again with a sacrifice fly to left by Blackmon that made it 2-1.

Singles by Francisco Alvarez and Nimmo set up the Mets in the third and they tied the game on a Lindor groundout.

Alonso sent one to the track to end the inning.

The Rockies took the lead for good in the fifth, with Diaz’s two-out hit scoring Grichuk from second to end Megill’s afternoon.

Nogosek allowed a two-run homer to Tovar in the sixth to make it 5-2.

These days, that’s a virtually insurmountable lead with this Mets lineup in which nearly everyone is slumping.

Starling Marte isn’t doing anything in the two-hole — and even tried to bunt twice when the Mets were in need of more base runners — and the reliable Alonso has picked a bad time to cool off.

Alonso entered Saturday hitless in his previous eight at-bats and slumping over his last 12 games.

“The toughest part [of this stretch] has to be staying within yourself and not trying to be something else,’’ Lindor said of an offense that was so solid a year ago looking punchless. “It’s baseball. I still believe we have one of the best teams out there. We just haven’t put it together collectively. I still believe in what we have. We are good. We’re gonna be great toward the end of the year.”

For now, they’ve got one more chance to get going against Colorado at home before heading back on the road to face Cincinnati and Washington.

And while both of those teams aren’t playing well, the Mets have now won just one of five games against the Tigers and Rockies, both also under .500.
