L.A. Dodgers pitcher Josh Ravin broke his arm in a car crash in Arizona on Monday -- and will require surgery ... but the good news, it's NOT his pitching arm.
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.
Ravin says he believes he was only going around 20mph at the time of the crash -- but the impact was hard enough that it snapped his left arm.
