"We're taking it one day at a time," Hurdle said of Harrison's status. "We'll see. I might have some different information for you tomorrow."
In Harrison's absence, Brent Morel got his third consecutive start at third base.
• Hurdle did not have any new information on Pedro Alvarez, who has not started since Aug. 26 due to a left foot sprain. The manager said the team is likely going to send medical info regarding the infielder to Pittsburgh to have it further examined.
Alvarez has appeared once since injuring the foot, as he pinch-hit against the Cubs on Friday.
