Speaking of the US Open......

An NBC employee who drove the golf cart for on course announcer Roger Maltbie was arrested during Saturday's third round. 

Tommy Lineberry faces four charges after an incident on the course with a North Carolina Highway Patrol officer.

Lineberry was charged with felony assault on a law enforcement officer, felony hit and run, driving while impaired, and resisting, obstructing and delaying a law enforcement officer.

A state trooper said he ignored instructions to stay put, then hit the officer with the golf cart on the 11th hole.

Lineberry who was likely contracted by NBC was released from a  jail after posting bail later Saturday night, officials said. NBC Sports said it was aware of the incident but declined further comment.
