This is the shocking moment San Francisco Giants CEO Larry Baer is seen pulling his wife off a chair and dragging her to the ground as she screams 'oh my god, help'.
The distressing footage was captured on Friday by an onlooker in a public park who said he heard the pair arguing before the altercation.
In the clip, a suited Larry, 61, can be seen standing over his wife's chair. He appears to be trying to pull a cell phone from her hand and the two tussle.
As Pam's chair falls to the ground Larry, who is said to make $5 million a year, continues to try and pry the phone from her hand as she lays on the floor, screaming.
The video then cuts as eyewitness say they then stepped in to help. It resumes with Larry seen shaking his head before walking away, telling her 'stop, Pam, stop'.
The man who shot the footage wishes to remain anonymous but said: 'I know this guy from somewhere and another guy said: 'That's Larry Baer'.
'He knocks her down off her chair and gets on top of her and puts his hands on her. She was screaming for help. She seemed pretty terrified.'
The incident, filmed in San Francisco's Hayes Valley, is now under police investigation. A spokesman told the DailyMail.com: 'We are aware of the incident at that location and we are investigating.'
Larry has since tried to play down their fight, telling The San Francisco Chronicle 'the matter is resolved'.
He added: 'My wife and I had an unfortunate public argument related to a family member and she had an injured foot and she fell off her chair in the course of the argument.
'The matter is resolved. It was a squabble over a cell phone. Obviously it's embarrassing.'
In a statement issued later through the team Baer said: 'I am truly sorry for the pain that I have brought to my wife, children and to the organization.
'It is not reflective of the kind of a person that I aspire to be, but it happened and I will do whatever it takes to make sure that I never behave in such an inappropriate manner again.'
One onlooker said he heard the couple, who have four children together, arguing for around 20 minutes. The row got so heated the witness said he heard Larry tell his wife: 'Let's go to counseling today.'
Pam, who married Larry in 1990, said in a statement to TMZ: 'We were having a family fight about someone in my family and that's it.'
Baer was named as chief operating officer of the Giants in May 1996, team president in October 2008 and CEO in 2012.
The couple also issued a joint statement through the Giants, saying: 'Regrettably, today we had a heated argument in public over a family matter. We are deeply embarrassed by the situation and have resolved the issue.'
A spokesman for Major League Baseball told DailyMail.com the league 'is aware of the incident and, just like any other situation like this, will immediately begin to gather the facts'.
They added: 'We will have no further comment until this process is completed.'
Baer was part of the ownership group that bought the Giants in 1992 to keep them in San Francisco, where the club won the World Series in 2010, '12 and '14. He took over as CEO on Jan. 1, 2012.
He earlier this week traveled to Las Vegas for a second time to meet with Bryce Harper, who wound up agreeing on a $330 million, 13-year contract with the Phillies.
