After snapping their longest losing streak in 41 years, the Yankees proceeded to extend a different skid that has been quieter, if just as devastating.

The Yankees won Wednesday, ending a run of nine straight losses that had consumed them, their worst losing streak since 1982.

They returned to The Bronx the next afternoon and completed a ninth straight series without a series victory.

The Yankees lost yet another set, this time crumpling late in a 6-5 loss to the Nationals in front of 39,681 unhappy fans on Thursday, thanks to a disastrous seventh inning.

The Yankees have not won a series since taking three games from the Royals from July 21-23.

After that sweep, Aaron Boone’s club was two games removed from the final AL wild card.

Just over a month and what has felt like a lifetime later, the Yankees (61-66) are 10 games back of the third wild card.

The Yankees, 0-7-2 in series since sweeping Kansas City, already have waved a white flag and will continue playing a pair of prospects (Everson Pereira and Oswald Peraza) during a 10-game trip through Tampa, Detroit and Houston.

Whenever hope has appeared — as it did with Aaron Judge’s fourth home run in two games, a first-inning blast; Gleyber Torres’ third-inning, two-run shot; and a late rally — frustration has followed.

Tommy Kahnle wore the face of frustration this time.

Kahnle entered in the seventh inning of a game the Yankees led, 3-1, and flushed it.

The righty inherited a runner on second (Carter Kieboom), who scored on a two-out single from Jake Alu.

Alex Call got a down-the-middle changeup from Kahnle and hammered it for the go-ahead, two-run home run to left-center.

The next batter, CJ Abrams, jumped on a full-count changeup and smacked it over the right-field wall.

Abrams admired his work for several seconds from the batter’s box, but the Yankees have bigger issues than violations of unwritten rules.

Kahnle had allowed two home runs in his first 31 games (28 ⅓ innings) and now has allowed three in his past two games, his ERA rising from 1.91 to 3.00 in a pair of games.

The Yankees could not come all the way back.

Giancarlo Stanton’s eighth-inning home run made it a one-run game, though the Nationals reclaimed the two-run edge by finding holes against Clay Holmes — the RBI single a tapper from Joey Menese — in the ninth.

In the bottom of the ninth, three singles (from Oswald Peraza, Torres and Stanton) brought the Yankees to within one again.

But with two out, Harrison Bader completed a rough, four-strikeout day with a deep fly out to center.

Wasted was a solid and short start from Michael King, who is being stretched out as a possible rotation solution for the rest of this season and perhaps next.

King’s stuff was solid for 2 ⅔ innings in which he allowed a hit, two walks and one run that should not have scored.

With Alu on third base with two out in the third inning, King induced a ground ball from Meneses, but Anthony Volpe booted it, allowing what was a tying run to score.

The tie did not last long, as Torres’ two-run shot — his 20th of the year — gave the Yankees a third-inning lead they would hold until Kahnle let it go.

The Yankees finished a six-game homestand against Boston and Washington with one win.

As has been the case all season, the breath of fresh air that was Wednesday’s victory was followed with a scent much fouler.
