Aaron Boone has used a position player twice on the mound to finish lopsided losses this year.

That is the biggest sign of surrender in baseball and the Yankees’ manager would be open to establishing a point in a blowout game where it ends instead of risking injury to a player doing something not natural.

“I think there would be a benefit to that,’’ Boone said Friday afternoon after moving Mike Ford from the DH spot to the mound for the final two innings of Thursday night’s 19-5 loss to the Indians at Yankee Stadium. “You would probably eliminate a lot of the unwritten rules, people running or swinging. It would be like, if you get to this point after seven innings or whatever, there might be something to that and worth exploring.’’

While Ford used the word “fun’’ to describe his two innings on the mound, when he gave up five runs and two homers in the eighth and worked a perfect ninth that ended with a strikeout, Boone said putting a position player on the mound isn’t funny.

“It is not fun to obviously put a position player in that situation,’’ said Boone, who used Austin Romine for an inning against the Red Sox on July 25 when the hosts hung a 19-3 loss on the Yankees. Romine gave up three runs and four hits, two of which were homers. “For Ford and some of the guys it is fun, but sitting in my chair, you worry about hurting someone, and sitting there getting kicked in the teeth is no fun. I am sure there is something to that question.’’

One hurdle to implementing a “mercy rule’’ is that advertisers pay for nine-inning games and some fans enjoy the rare games when a position players take the mound.

And with some of the changes coming to rosters for the 2020 season, teams might be able to avoid using a position player to pitch.

From Opening Day through Aug. 31 next year and in the postseason, the active roster will increase from 25 to 26 and the minimum number of active players increases from 24 to 25. There will also be a 27th man for doubleheaders.
