Worried about the Mets’ rotation after the first turn through? Does Noah Syndergaard’s blister have you ready to burst? Are you concerned Zack (Wheeler) might not be back? Are you not Gsold yet on Robert Gsellman?

Two words: Jeremy Guthrie.

Jeremy Guthrie is a dime-store righthander the Washington Nationals started against the Phillies on Saturday night. The good news is he got two outs. The bad news is he was charged with 10 runs as the Phillies scored 12 in the first inning.

Sooooo Mets fans . . . you think you’ve got problems? Welcome to the club. Everybody has starting pitching problems and the Mets have fewer than most.

The Nationals, the Mets’ chief competition in the NL East, had to dip into the minors for a 38-year-old guy who didn’t pitch in the majors last year to start the fifth game of the season.

The Mets already have suffered setbacks in their rotation depth. Steven Matz and Seth Lugo are on the disabled list with arm injuries and no one is sure when they will be back.

Syndergaard will test his blistered middle finger against the Marlins on Sunday night. Wheeler underwhelmed on Friday in his first start since 2014.

Gsellman was a little shaky in the Mets’ 8-1 loss to the Marlins on Saturday night at Citi Field. He allowed three runs — one in each of the first three innings — and only went five innings.

Still, the most important thing that has happened to the Mets in the season’s first five games are the performances of Syndergaard, Jacob deGrom and Matt Harvey.

Syndergaard on Opening Day: six innings, no runs, seven strikeouts, one blister.

DeGrom the next game: six innings, no runs, six strikeouts.

Harvey: 6 2⁄3 innings, two runs, four strikeouts, multiple “Dark Knight is back” references.

The Mets’ fortunes this season will not rest on the fourth and fifth starters. If Syndergaard, deGrom and Harvey are as good as they each can be, and as healthy as you hope they will be, the Mets can afford OK-to-good performances from the back of the rotation, at least until they re-acquire Bartolo Colon from the Braves in July.

Yes, that is going to happen. Big Sexy will be back. Bet on it.

Gsellman was OK-to-good on Saturday night. The Marlins squared up his pitches with regularity, especially in the first three innings, and the righthander seemed to be teetering on the edge of disaster most of the night.

“He certainly didn’t have his sinker early in the game at all,” manager Terry Collins said. “I think he settled in later and made some better pitches. Some of the balls that were struck . . . He made a lot of mistakes.”

In the first, Miguel Rojas ripped a double with one out and Giancarlo Stanton drove him home with a hard two-out single (How hard? See below).

In the second, Marcel Ozuna walloped a 3-and-2 pitch into the second deck in leftfield for a leadoff home run.

Since it’s a Statcast world and we just live in it, please know that Ozuna’s home run traveled at 111 mph. That wasn’t as fast as Stanton’s single to left, which went 111.7 mph.

J.T. Realmuto opened the third with a liner that sailed over Curtis Granderson’s head in centerfield and went for a gift triple. Rojas hit a long sacrifice fly to center to give Miami a 3-0 lead.

Gsellman kept it there and finished having allowed six hits and two walks with seven strikeouts. It was 3-1 when he departed. It’s not his fault the Mets’ bats are like wet noodles right now. Gsellman (cliché alert) kept his team in the game.

Sure, if you’re a Mets fan you started spring training dreaming of five aces.

So did Nationals fans.
