Ian Poulter lost his grip on the top of the leaderboard and Webb Simpson promptly claimed it during the second round of play at the RBC Heritage in Hilton Head, South Carolina.
Simpson (-12) entered the day tied for third at six under and duplicated his Thursday feat to take sole position of first place heading into the weekend.
The biggest story of the day was who didn't make it onto the course for their tee time.
Nick Watney was forced to withdraw after testing positive for the coronavirus Friday morning after he began showing symptoms consistent with COVID-19.
