PITTSBURGH -- The D-backs on Saturday removed Alberto Callaspo from the restricted list, and the infielder was in uniform for Saturday night's game against the Pirates.

Callaspo was placed on the restricted list May 10, one day after police were called to his residence following an alleged altercation between Callaspo and his wife, Marianny Paola.

"I look forward to putting this unfortunate matter behind us, and focusing on helping my teammates win on the field again," Callaspo said in a written statement issued by the club. "I apologize to the players, the organization and our fans for any distraction that this may have caused."

Callaspo had not contributed much to the D-backs prior to the incident. The switch-hitter was batting just .215 with no home runs and three RBIs.

The D-backs said that Callaspo was placed on the restricted list because he did not report for the team charter flight to Houston on May 10. At that time, he was being questioned by police. Players who are on the restricted list do not get paid, and the players' union had filed a grievance earlier this week on Callaspo's behalf that challenged the D-backs' decision to put him on the restricted list, claiming that he was indeed ready to play.

The D-backs, the union and Callaspo all agreed that the infielder would be examined by an independent certified Employee Assistance Program expert, and that all parties would abide by the counselor's recommendation.

On Friday, the counselor reported to the parties that it was her recommendation that Callaspo be allowed to return back to work.

"We collected the pertinent information and offered Alberto the services of a counselor," Diamondbacks president Derrick Hall said in a statement. "The expert met with Alberto yesterday and found the player fit for work, but recommended he undergo counseling. Alberto and the club have agreed to the recommended counseling. I am proud of the manner in which our entire staff has handled this sensitive situation."

Had the D-backs elected to send Callaspo to the Minor Leagues or suspend him after the counselor made her recommendation, the union would have most certainly filed a grievance, and the club felt it would have been forced to put him back on the active roster.

Callaspo has yet to be formally charged by police.

Hall said he stood by an early statement which said the club did not "condone" the behavior Callaspo has been accused of.

"But as we've been saying all along, we also believe in second chances," Hall said. "We're glad that Alberto can get help."

Callaspo flew to Pittsburgh on Saturday and joined his teammates while they stretched prior to batting practice.

"More than him coming back, and more than him being physically able to play, my concerns always have been and always will be for he and his family," said D-backs veteran Tony Clark, a high-ranking member of the union. "We're happy to have him back and what he does for our ballclub."

D-backs manager Bob Melvin met briefly with Callaspo when he arrived, but said that he didn't expect Callaspo would address his teammates as a group.

"He's been in contact with some of our guys," Melvin said. "I've talked individually and in small groups with our guys, and they're aware of the situation, and I don't think he really needs to say anything to the team. He probably will individually talk to guys. His statement speaks for itself, and I don't think he needs to get up and say anything to his teammates right now."
