Phoenix ? A man was arrested on a homicide charge Thursday night in the death of Cincinnati Reds outfielder Dernell Stenson, and police said they were seeking a second suspect.

Reginald Riddle also was charged with armed robbery and kidnapping, Chandler, Ariz., police said.

Early Wednesday, Stenson’s body was found in a street in a residential neighborhood in the Phoenix suburb. He had been shot, then run over and apparently dragged some distance by his own SUV.

Riddle, originally from Illinois, is the half brother of Kevin Riddle, 43, who was found driving Stenson’s SUV about two hours after the body was found.

Kevin Riddle was charged earlier with possession of stolen property, police said. Authorities are seeking a third man, David Griffith, who police said should be considered armed and dangerous.

Stenson, 25, made his major-league debut with the Reds this year, batting .247 with three home runs and 13 RBIs in 37 games. His last home run accounted for Cincinnati’s final run of the season.

Stenson was having a big season in the Arizona Fall League, where up-and-coming players are sent to hone their skills. He was batting .394 — third-best in the league — through 18 games.

The Arizona Fall League canceled games Wednesday and Thursday. Play was to resume today.

Stenson was claimed by the Reds off waivers from Boston Feb. 25 after seven seasons in the Red Sox minor-league organization.
