"Just in case he answers," Soriano said.
Zambrano was placed on the restricted list Tuesday. He was scheduled to meet Wednesday in New York with doctors selected by Major League Baseball and the Players Association to help him deal with anger issues. What type of counseling he will receive or program he'll be placed on will then be determined. He will not rejoin the Cubs until after the All-Star break.
"I'm very happy that he has somebody to help him," Soriano said, "and I hope when he comes back, he can be 100 percent and help the team win."
Soriano tried to call Zambrano after the tantrum happened on Friday at U.S. Cellular Field, but had the wrong number. He tried again Sunday, but Zambrano didn't answer.
"Sometimes he can't control his emotions," Soriano said. "That's his problem, but other than that, he's a great guy. I hope everybody gives him support, because he's part of the team."
The Cubs now need to focus on the National League Central. They entered play Tuesday 9 1/2 games back.
"We have a lot of things to do," Soriano said. "We're not playing good right now and we have to find a way to play better."
