CLEVELAND — A lax security detail at Progressive Field failed to keep a female from jumping into the Yankees’ bullpen Friday night and touring the pen shaking relievers’ hands.

During the ninth inning of the Yankees’ 5-2 loss to the Indians, the woman dropped into the bullpen while the security detail was watching the final three outs and didn’t see the dumb move.

Bullpen coach Mike Harkey alerted security to the situation, and the woman, who is from southern Ohio, was arrested. She will remain in jail until Monday.

“She shook all our hands except Chad Green,’’ Zack Britton said of the woman who described herself as a Yankees fan.

None of the relievers were injured, but the possibility that could have happened is why bullpens are supposed to be protected by security, with customers very close in most stadiums.

“It seems funny but in reality, [if you] think about it, if somebody wanted to do something down there they could do it fairly easy,’’ Britton said.

According to Britton, the woman was attempting to get into the pen for a while and finally did it, jumping down 10 feet.

“There were police officers up there, there is team security from the Indians and they didn’t see it happen until she was kind of hanging out in the bullpen,’’ Britton said. “She said she was a Yankee fan and she wanted to meet us. Obviously intoxicated, but impressive jumping. She said she wanted to meet everybody. That’s a weird way to do it.’’

Giancarlo Stanton could begin a minor league rehab assignment Monday or Tuesday, manager Aaron Boone said.

“I think the plan right now is a few games with [Single-A] Tampa, possibly Tuesday, Wednesday and Thursday and transfer him to [Triple-A] Scranton,’’ Boone said of Stanton, who played the first three games of the season and has been on the injured list since, first with a strained left biceps then a strained left calf. “Evaluate where he thinks he is, evaluate how many at-bats in those kind of game situations. He has had a lot of live at-bats, so maybe when he starts the rehab, maybe he won’t take as long as some guys.’’

Asked if Aaron Judge, on the IL with a strained left oblique, could be playing games in two weeks, Boone said, “Not for us, but possible.’’

Luis Severino threw off flat ground from 75 feet Saturday.

“He is still a little ways away from the mound but every step of the way has gone pretty well,’’ Boone said. “He will have to get back to 120 [feet].”

The Yankees placed Masahiro Tanaka on the paternity leave list on Saturday, a day after the right-hander and his wife welcomed a daughter. Tanaka was scheduled to start Sunday, but instead will start Monday night against the Mets in the first Subway Series game of the season.

Tanaka was scheduled to throw a bullpen session Saturday at Yankee Stadium.

The Yankees will use a reliever to start Sunday’s game. Boone said Chad Green (who has done that three times) will “probably” start after not being needed in Saturday’s loss.

Nestor Cortes Jr. was recalled from Triple-A Scranton/Wilkes-Barre to take Tanaka’s roster spot.

Troy Tulowitzki has not returned to the Yankees’ complex in Tampa from his home in Las Vegas, and Boone wasn’t sure where the situation stands.

“I think he is trying to weigh everything that is going on in our organization and where he is at. Obviously it has been a tough time from battling back and getting back and having a setback,’’ Boone said of the shortstop, who played five games and went on the IL with a strained left calf. “[He’s] trying to take some time to go through things with his agent and family, so we respect that.’’
