L.A. Dodgers pitcher Josh Ravin SNAPPED his non-pitching arm in a car crash in Arizona on Monday -- and will require surgery ... and TMZ Sports has photos of the nasty injury.
We spoke with Ravin who tells us ... he was behind the wheel in his car when traffic suddenly came to a stop and his first instinct was to swerve to avoid hitting the car in front of him.
Problem is ... he went into oncoming traffic and collided with another vehicle.
