CHICAGO -- Don Cooper, who previously missed 11 games due to vertigo, left Monday's games with the same issue and was not at U.S. Cellular Field on Tuesday. It doesn't seem likely that the White Sox pitching coach will be traveling with the team for four games this weekend in Seattle, followed by two games in San Francisco next week.
"He has a lot of information, so you always like him when he's here," said manager Robin Ventura of Cooper. "He's seen these guys from Spring Training on so just the feeling of having him here and working with the guys.
"But if he's not feeling well, you get a different feel. You feel bad for him. You think he's starting to feel better and he's not. It's our loss that he's not here."
