St. Louis Cardinals outfielder Oscar Taveras, a 22-year-old slugger who was regarded as one of the majors' top prospects, died Sunday in a car accident in his native Dominican Republic.

Taveras was driving a 2014 Chevrolet Camaro at the time of the crash on a highway between the beaches of Sosua and Cabarete in Puerto Plata, about 215 miles north of the capital of Santo Domingo, said Col. Diego Pesqueira of the Metropolitan Transportation Agency.

"He wasn't carrying documents at the time of the accident, but his body was identified by family members," Pesqueira said. National police spokesman Jacobo Mateo Moquete said he was told by the mayor of Sosua that Taveras lost control of his vehicle and went off the road.

Taveras' girlfriend, Edilia Arvelo, 18, who was in the car with Taveras, also died in the accident.
