Tommy Armour and Bob Estes share the clubhouse lead in the opening round of a PGA event in Port St. Lucie, Florida.
Estes birdied six straight holes for a 9-under-par 64 that gave him a piece of the lead. He had no bogeys and capped his round with a 40-foot birdie putt on the par-4 ninth hole.
Armour caught Estes by closing his round with three straight birdies. Armour completed his final hole after play was suspended by darkness.
Craig Kanada and Daniel Chopra are tied for third at minus-6.
Greenville native Will Mackenzie withdrew after shooting a six over par 79.
Twenty-two players will try to complete their opening round on Friday.
