CHICAGO -- White Sox pitching coach Don Cooper missed his second straight game on Monday due to a bout with vertigo.
"So it's possible he won't be here for a few days," manager Robin Ventura said on Monday. "He had it yesterday. Not feeling too good. I talked to him today. I've never had it, but by listening to him it doesn't sound very good. Yesterday, he just thought he felt bad and felt dizzy."
Bullpen coach Bobby Thigpen will serve as the club's pitching coach in Cooper's absence. Bullpen catcher Mark Salas fills in for Thigpen in the interim. Cooper missed 10 games from April 9-18 and three from Sept. 6-8 last year with diverticulitis.
