The pretrial hearing set ground rules for the case should the former Diamondbacks player and TV analyst appear before a judge and jury.
Former Diamondbacks player and announcer Mark Grace will appear in court on Wednesday. He's having a pretrial conference for his four felony DUI charges.
48-year-old Grace of Paradise Valley was pulled over in Scottsdale in late August for having expired registration tags on his vehicle.
After speaking with Grace and administering standard field sobriety tests, the officer took Grace into custody for DUI.
Scottsdale Police say that Grace was driving without the required interlock device and that his license was suspended for a prior DUI in Scottsdale from May 30, 2011.
His blood was submitted for testing and he was released. Testing showed Grace had a blood alcohol level of .095.
Grace could spend up to 3.75 years in prison if convicted of all 4 counts of aggravated DUI. The charges are aggravated because he was driving without the required interlock device and with a suspended license.
The law requires people with a first time felony DUI offense to spend at least four months in a DUI facility at the Department of Corrections. But anyone with a DUI charge serving a year or less goes to Tent City.
During his career in professional baseball, Grace played first base for the Chicago Cubs, and played for the Diamondbacks during their World Series win.
The Diamondbacks announced in August that Grace was taking leave from broadcasting to "seek personal assistance." He has since been replaced.
Grace is next expected to appear in court on Jan. 31 and will start his trial on March 19.
