After a Friday-morning conversation with White Sox chairman Jerry Reinsdorf and general manager Ken Williams, Ozzie Guillen told his son Oney to resign his post as Minor League video coordinator and move on to other ventures. "It's hard when you see your kids and tell them, 'I just told the people you got to resign,'" said Guillen, who walked out of the White Sox complex on Friday without speaking with the media. "I think that's the hardest thing I ever did in my life. "I feel very sick all game because I never thought I was going to be in that situation. I think Oney knows baseball more than a lot of people in the game. When your kid's wrong or right ... I thank God my kid was wrong in that and not doing drugs or stupid stuff out there. You got to be the first to admit it. "He's getting paid by the White Sox, and he has to respect the rules of the White Sox. He has to respect Jerry Reinsdorf. That's the most important person in the organization. If you don't respect Jerry, you don't respect myself. "That's what my kid did, and like I say, people learn by mistakes. He'll find a lot of jobs. They were calling left and right a couple of days ago."
