San Francisco Giants CEO Larry Baer was captured on video roughing up his wife in a public plaza on Friday — knocking her to the ground as she screamed for help in an incident that’s now being investigated by police.

Baer is seen violently grabbing for his cellphone, which was in Pamela Baer’s hand, as she’s sitting in a chair in the city’s Hayes Valley neighborhood around 11:30 a.m. local time, according to video published by TMZ and witness accounts to the San Francisco Chronicle.

Pamela Baer falls over and spills to the ground while screaming, “Oh my God, no, help!” the video shows.

In another clip, Larry Baer is heard telling his wife, who is off camera, “Stop, Pam, stop” while a witness says “Get the f–k away from him.”

The witness who took the video told cops the couple were having a “very emotional conversation” that went on for about 20 minutes before Pamela Baer grabbed her husband’s cellphone and the row got physical, according to the Chronicle.

Another witness who heard the argument as it escalated told the paper Pamela Baer could be heard saying, “Larry, sit down, sit down.”

The videotaping witness said it then turned violent.

“He knocks her down off her chair and gets on top of her and puts his hands on her,” the witness said. “She was screaming for help. She seemed pretty terrified.”

The witness then stopped recording and ran to help with some other guys in the plaza.

“As soon as he felt someone else grab him, he relaxed and got off,” the witness said.

The CEO, who’s been with the Giants for decades and was named to his current post in 2012, provided a statement to the outlet calling the incident “embarrassing.”

“My wife and I had an unfortunate public argument related to a family member & she had an injured foot and she fell off her chair in the course of the argument,” the statement says.

“The matter is resolved. It was a squabble over a cell phone. Obviously, it’s embarrassing.”

Pamela Baer told TMZ, “We were having a family fight about someone in my family and that’s it.”

Major League Baseball put out a statement shortly after the scuffle saying it is aware of the incident and will be investigating the situation.

The video emerged amid MLB’s spring training and hours before the team was set to play the Cincinnati Reds in Scottsdale, Arizona.

According to a 2008 profile of the couple published by the outlet, the couple met at a 1988 birthday party in New York and have four grown children.
