2:50 PM PT -- The MLB has confirmed Urias has been placed on administrative leave while the league conducts an investigation into the matter.
An MLB rep says the administrative leave is effective today and can last up to 7 days.
Sources tell TMZ Sports the administrative leave can be extended -- potentially multiple times -- while the investigation is active.
Bottom line -- it could be a while before Urias takes the mound again.
8:55 AM PT -- The Dodgers are commenting on the Urias arrest ... telling TMZ Sports, "We learned about the alleged incident this morning and are in the process of gathering information."
"As a result, we have no comment at this time regarding the incident. However, every allegation of domestic violence must be taken seriously and addressed promptly, and we will cooperate fully with the authorities and Major League Baseball to ensure that that happens in this case."
L.A. Dodgers pitcher Julio Urias -- a rising star in the organization -- was arrested for domestic violence Monday night ... TMZ Sports has learned.
The 22-year-old was arrested at 9:30 PM in Los Angeles after an incident at the Beverly Center, an upscale shopping area.
We're told a witness called cops claiming Urias was in the parking lot arguing with a female companion and shoved her to the ground.
Cops responded and spoke with the woman, who denied anything physical took place ... and insisted it was nothing more than a heated verbal argument.
However, sources connected to the situation tell us ... witnesses were adamant they saw Urias push the woman and video from the scene appeared to back up the witness accounts.
Urias was arrested and transported to a nearby station where he was booked for misdemeanor domestic battery.
He spent the night behind bars and bailed out early Tuesday morning after posting $20,000 bail.
The left-hander made his MLB debut in 2016 when he was 19 years old. He missed a lot of time over the last couple of years due to injuries but he's been on fire in 2019, winning 2 games and saving 2 games for the 1st place Dodgers so far this season.
