Stating that "I have nobody to blame but myself," Mark Grace said Monday that he understands why the Arizona Diamondbacks fired him last season from his job in the broadcast booth.

Grace, a former Diamondbacks and Chicago Cubs first baseman, faces a March19 trial on four felony counts of aggravated DUI following an August arrest in Scottsdale.

"I did this," he said. "The Diamondbacks didn't do anything. I think it's important to own this. I own this."

Grace's remarks came at the team's spring-training site, Salt River Fields at Talking Stick, where the Diamondbacks held their eighth annual fantasy camp, an interactive program for fans.

Grace participated in the seven previous camps but didn't think he would have the opportunity this year after the team announced on Oct.4 that he wouldn't return to the booth.

Several weeks ago, however, the team reached out to Grace about participating, and "I was happy to grab that olive branch," he said.

"Mark has always been an important part of our family, so we would naturally be here to support him," Diamondbacks President Derrick Hall said. "While he still has some legal issues to overcome, we look forward to his future involvement in the organization."
