Cardinals pitcher Kyle Lohse could miss another start because of a sore arm. St. Louis pitching coach Dave Duncan said after a bullpen session on Friday that Lohse is "about 75 percent." Duncan added that there is "a 90 percent chance" that he'll miss his scheduled start against the Reds on Tuesday. Lohse continues to suffer from stiffness in the area where he was struck by a pitch against the Royals on May 23. "It's become frustrating because it's not getting better," he said.
