Belisario was with the Dodgers in Denver as they got set to take on the Rockies on Thursday afternoon. His attorney entered the plea at his arraignment and a pretrial hearing was scheduled for October.
Belisario was arrested on suspicion of driving under the influence of alcohol early on June 27, as California Highway Patrol officers initially pulled him over because they said they saw him talking on his cell phone while driving. He was then released on $5,000 bail.
A native of Venezuela, Belisario sports a 2.30 ERA in 51 games during his rookie season. The 26-year-old right-hander was signed as an amateur free agent by the Marlins in 1999 and spent six seasons in the Minors before making his Major League debut earlier this year.
