It was another wild day along the Calibogue Sound, as the leaders faltered and the tournament winner came from the chase pack. Here's how things ended up at the RBC Heritage, where C.T. Pan rallied to claim his first career PGA Tour victory:
Leaderboard: C.T. Pan (-12), Matt Kuchar (-11), Patrick Cantlay (-10), Scott Piercy (-10), Shane Lowry (-10)
What it means: It was a crowded leaderboard once world No. 1 Dustin Johnson began to falter, with as many as five players sharing the lead at one point on the front nine. But on a day when birdies were hard to come by, Pan edged out the field with a 4-under 67 that included three back-nine birdies and a horseshoe lip-out on the final green.
