If the first five games of the month represented hope for the future, the Yankees delivered a reminder of the immediate past Thursday night.

A reminder that Carlos Rodon has been one of the biggest disappointments in a season in which he has had plenty of competition.

A reminder that the team’s offense, for much of this year, has lacked punch and made any kind of deficit feel insurmountable. A reminder that this season, barring a miracle, is over.

Rodon was booed off the mound and took any momentum with him as the Yankees’ five-game winning streak was halted in a 10-3 loss to the Tigers in front of 32,722 in The Bronx.

“We were on a roll there with five straight wins,” said Rodon, whose Yankees dropped just their second game in their past 10. “Just trying to put the next one up. Showed up and kind of pissed the bed.”

The Yankees (70-70) fell seven games back in the wild-card chase.

Strong efforts primarily from the kids and the rotation have brought a remote aspiration of the postseason into play, but another clunker from Rodon reminded of the realities surrounding that pipe dream.

The big lefty was signed as the one clear upgrade from last season, a starter the Yankees brought in to put them over the top.

He, along with a lackluster offensive attack, instead has helped bury the club. Rodon was hit hard and often by Detroit during 3 ²/₃ innings in which he allowed seven runs on eight hits.

“Stuff was a little down, a little all over the place,” said Rodon, whose ERA sits at 6.60 after 10 starts. “They barrelled a lot of balls. Just got my ass whooped.”

Rodon has never lacked accountability but has lacked results.

After forearm and back issues kept Rodon from pitching until July, he returned without the stuff that made him an All-Star the past two seasons.

His season has been filled with starts and stops and included another IL stint in August due to a hamstring strain.

He had put together three solid efforts in a row (in which he allowed five runs in 15 ²/₃ innings) entering play, but again a step forward was met with a step back.

The Yankees are still waiting to see the often unhittable pitcher Rodon has been in the past.

After another dud, his manager subtly lowered the expectations: Aaron Boone did not pine for a quick bounce-back and a long-shot run at the postseason behind Rodon’s arm, but instead wished for a solid final few weeks that would bode well for next season.

“We just got to hopefully finish strong this month,” Boone said of Rodon, “and put ourselves in a position to really springboard strongly into next year with his stuff.”

His stuff, notably his velocity, was down a tick Thursday.

Even several outs were crushed, a few deep fly outs falling a few feet short of home runs.

Spencer Torkelson ensured several of his swings had the distance.

The young slugger put the Tigers up 2-0 two batters into the game with a tone-setting and hope-evaporating home run.

Detroit added two more runs in the third, then prompted the first round of boos in the fourth inning, when Tyler Nevin drilled an RBI double. Matt Vierling’s single scored a sixth run and chased Rodon from the game.

The second pitch Randy Vasquez threw in relief became Torkelson’s second home run of the game, putting the Yankees in an 8-1 ditch they would not climb out of.

“It’s obviously not ideal, but I thought we put together good at-bats the rest of the night,” Anthony Volpe said.

Gleyber Torres drilled a second-inning home run, and Everson Pereira’s fourth-inning double drove in two.

But the Yankees’ offense managed just six hits against Eduardo Rodriguez and three Tigers relievers.

The lineup, which has been boosted by the energy of the youth and a few signs of life from the veterans, reminded of the year-long struggles.

Rodon reminded of the expectations he and the Yankees had entering this season that have not been met.

“I haven’t performed very well,” Rodon said, “and haven’t performed very much.”
