Hawkins was placed on the 15-day disabled list before the game because of a shingles (that's different) and Wright went to a Chicago hospital after the game with a possible case of appendicitis."To lose [Oswalt] at this point of the year is not a good idea," teammate Miguel Tejada said. "Everybody is crossing their fingers that he will be OK in a couple of days."Oswalt, who is flying back to Houston so team docs can check him out, said he has felt discomfort since his previous start July 22.
