L.A. Dodger James Loney Crashes Maserati -- Allegedly Spits at Cops

Los Angeles Dodgers star James Loney was arrested while being hospitalized in L.A. last month ... after allegedly smashing his Maserati into THREE other cars ... and then spitting at a cop ... this according to a police report obtained by TMZ.

Loney -- who plays 1st base for the Dodgers -- was arrested on November 14th ... because cops say he appeared to be under the influence of drugs after he swerved into a Toyota around 6pm ... and then careened into a Mercedes and a Mini.

According to the report, when cops first arrived to the scene ... Loney told one of the officers, "The bitch hit me from behind."

Cops say Loney appeared to be "restless, unsteady, aggressive and irritable" ... and he "exhibited eyelid tremors and his shirt was soiled and moist from perspiration, from his armpits down to his waistline."

Cops say when officers asked Loney what day it was ... he replied, "7/15 and Saturday" -- when in fact, it was 11/14 and Monday.

Loney was handcuffed and transported to a nearby hospital -- where an officer attempted to give him a breathalyzer test.

But according to the report, Loney was "uncooperative" -- biting off the mouthpiece and spitting it back at the cop.

Cops say Loney began to get aggressive with police ... so they placed him in arm and leg restraints ... and a member of hospital staff gave him "an injection" to calm him down.

Loney was released to the care of the hospital and was never brought to the police station for formal booking.

Still, cops say they obtained a blood sample to test for drugs and alcohol ... but it came back NEGATIVE. Now the case is in the hands of the L.A. City Attorney's Office.
