The lead is still holding for Davis Love III and Matt McQuillan, each of whom opened with a 64 Thursday. But they’ve got company in Steve Marino, who is 6 under through 13 holes.

Marino has birdied his last four holes and he still has a par-5 to go in No. 17. In all, he has eight birdies and just two bogeys.

The biggest boost to Marino today? His putting. He’s averaging 1.11 putts per green in regulation, and he’s hit just under 70 percent of his greens so far.

If he keeps that up, it won’t be long before he passes Love and McQuillan.
