The 2023 baseball season is just a day old, but the blood is already boiling in southern California.

After his team's 2-1 loss to the Oakland Athletics, the Los Angeles Angels' Anthony Rendon was caught on camera gripping an A's fan by his shirt and swinging an open hand toward the fan's head.

It's unclear exactly what sparked the confrontation, but Rendon claimed the fan called him a b----.

"What'd you say? You called me a b----, huh. Yeah you did. Yeah you did. Yeah motherf----," Rendon told the fan while gripping his shirt.

That's when Rendon let go of his grip and then tried to swipe at the fan's A's hat.

Angels teammate Mike Trout stopped in his tracks to witness the war of words, but everyone walked away before things got worse.

MLB said it is investigating the incident.

"We are aware of the video, and we are now looking into the matter," MLB said in a statement.
