ATLANTA — The Yankees are underwater, and sinking lower each day.

How many rock bottoms can one team hit in a season?

For the second straight game, the Yankees were shut out by the Braves, this time in a 2-0 loss on Wednesday night that plunged them under .500 for the first time this season and completed a three-game sweep at Truist Park.

Capping off a miserable 2-7 road trip in fitting fashion — they were outscored 18-3 by the Braves (78-42) in this series — the Yankees (60-61) headed back home as a sub .500 team for the first time since May 1, 2021.

With their playoff chances continuing to dwindle, the Yankees’ biggest fight over their final 41 games may be trying to avoid their first losing season since 1992.

It marked the first time the Yankees have been shut out in back-to-back games since Aug. 14-15 of last season against the Red Sox and Rays.

After they were one-hit by Bryce Elder on Tuesday, the Yankees mustered four singles against Charlie Morton and the Braves’ bullpen on Wednesday.

Morton cruised through six innings while striking out 10 and walking only one before three relievers combined for three perfect innings and added three more strikeouts.

The final 12 Yankees were retired in order to end the night without any kind of a fight.

The Yankees gave Randy Vasquez the opportunity to start Wednesday instead of pitching behind an opener, as he did on Friday against the Marlins. Vasquez was fine in another abbreviated outing, giving up two runs over 3 ¹/₃ innings.

After he struck out Ronald Acuña Jr. and Matt Olson in a scoreless first inning, Vasquez got into trouble in the second. He was ahead 1-2 in the count when Marcell Ozuna roped a double over the head of Giancarlo Stanton in right field. Eddie Rosario came up next and crushed the first pitch the other way for a two-run home run.

Vasquez settled down from there and retired seven straight before walking back-to-back hitters with one out in the fourth inning.

Manager Aaron Boone then pulled Vasquez for Michael King — who had been in consideration to open the game — and the reliever quickly put out the fire. King went on to throw 3 ²/₃ dominant innings while continuing to stretch out to 44 pitches.

But the fact King kept the deficit at two runs hardly mattered because the Yankees could not muster any kind of offense for the second straight night.
