Dealing with vertigo, Cooper doesn't make trip to Seattle

CHICAGO -- White Sox manager Robin Ventura confirmed Wednesday that pitching coach Don Cooper will not make the trip to Seattle because of his ongoing battle with vertigo.

Cooper is the leader of the White Sox staff, although as John Danks pointed out Tuesday night, bullpen coach Bobby Thigpen is a knowledgeable pitching mind and in on all the meetings. So the team's recent struggles can't be directly tied to Cooper's absence.

"You would like to have him back," said Ventura of the effect caused by Cooper's absence over 13 games, non-consecutively. "I don't know if it's 16 runs worth, but we'd like to have him back and be here working. I'd like to have him here. He would like to be here. Pitchers would like him to be here. But I don't think it's 16 runs worth.

"He's just not feeling any better. It wouldn't do him any good to get him on a plane. The doctors have basically said 'Don't fly. That would be the worst thing you could do right now.' Just be here, get some treatment and figure out what's going on."
