The Rocket Mortgage Classic evokes special memories for Cam Davis, who is three strokes off the pace and right in the mix midway through this year's edition.
The tournament is close to the heart for the 29-year-old Australian, whose only victory on the PGA Tour came at the event three years ago.
Davis gave himself another chance at victory on Friday, calmly posting a six-under 66 to go with his opening 68 to be 10 under.
