LOS ANGELES, California (CNN) -- Los Angeles Angels pitcher Nick Adenhart was among three people killed in a crash in Fullerton, California, early Thursday, according to media reports.

CNN affiliates KTLA and the Los Angeles Times as well as TMZ.com identified the victim as Adenhart, 22, from Silver Spring, Maryland.

A top prospect in the Angels organization, Adenhart had pitched six scoreless innings in Wednesday night's game against the Oakland A's for his fourth major-league start.

One person was arrested in connection with the three-vehicle accident that occurred about 12:23 a.m. Thursday in Fullerton, south of Los Angeles. Witnesses say a red minivan ran a red light and struck two vehicles at a Fullerton intersection, police Lt. Craig Brower said.

One of the vehicles, a gray Mitsubishi, slammed into a power pole, Brower said. Two of its passengers were dead at the scene, he said. The other two were transported to a hospital, where a third later died. The remaining passenger was in critical condition, Brower said.

A passenger in the minivan was taken to a hospital with minor injuries, Brower said. The third vehicle sustained minor damage, and its driver was unhurt, he said.

The minivan's driver fled the scene and was later arrested, Brower said. Andrew Thomas Gallo, 22, of Riverside will face charges of manslaughter, felony driving under the influence and hit-and-run, he said.

Footage from the scene showed the minivan with a smashed front end and the Mitsubishi, which was heavily damaged. Debris littered the intersection where the crash took place, and it was cordoned off with yellow police tape.
