Cincinnati Reds manager Dusty Baker left Wrigley Field on Wednesday to have chest X-rays performed in an attempt rule out pneumonia, a team spokesman said.

Baker left the stadium in street clothes just hours before the NL-Central leading Reds were to face the Chicago Cubs. He showed no signs of illness and was examined by a member of the Cubs medical staff before departing for the hospital.

Cincinnati bench coach Chris Speier will manage the team, should Baker not return before game time.

Baker managed the 3,000th game of his career on Tuesday.
