Geoff Hartlieb’s second chance with the Yankees went as poorly as the first.

And it prompted the Yankees to designate the right-handed reliever for assignment on Wednesday for the second time in a week.

The 31-year-old journeyman gave up three runs on three hits and a walk in just ⅓ of an inning in the Yankees’ 10-3 win over the Mariners Tuesday night in The Bronx. That included a two-run home run by Cal Raleigh in the eighth, the stud catcher’s MLB-best 36th homer of the season.

That followed a rough outing against the Blue Jays on July 1, when Hartlieb surrendered three runs on two hits and three walks in one inning.

The Yankees first DFA’d Hartlieb last Wednesday, and on Friday he elected free agency instead of accepting an outright assignment to Triple-A Scranton/Wilkes-Barre.

But the Yankees re-signed Hartlieb to a major league deal before Sunday’s Subway Series finale against the Mets while optioning lefty Jayvien Sandridge to Triple-A.

Hartlieb, who spent last season with the Rockies and made three MLB appearances with the Mets in 2021, has a 3.34 ERA with 38 strikeouts in 35 innings with Scranton/Wilkes-Barre this season.

Wednesday’s move creates a roster spot for right-handed pitching prospect Cam Schlittler, who will start and make his MLB debut Wednesday night.
