ESPN moutpiece Jay Mariotti was arrested last night in Los Angeles. According to reports, the sportscaster was arrested on “suspicion of felony” apparently stemming from a domestic dispute with his girlfriend.

The dispute must have been pretty serious with Mariotti being held on $50,000 bail.

Mariotti is best known for his role on the popular discussion show Around The Horn and he also provides a column for Fanhouse.com. Mariotti used to write for the Chicago Sun-Times but was fired.

We’ll post more as news from the arrest is made public.
