AVONDALE, La. (AP) _ Kevin Kisner and Scott Brown teamed to shoot an 8-under 64 in better ball on Saturday to take a one-shot lead heading into the final round of the Zurich Classic.

The duo lost on the fourth hole of a playoff to Cameron Smith and Jonas Blixt last year, the first for the Zurich as a team event. They're in contention once again atop a crowded leaderboard at 20-under 196.

Tony Finau and Daniel Summerhays shot a bogey-free 63, and Michael Kim and Andrew Putnam teamed for a 66 to finish one shot behind Kisner and Brown. There were 13 teams within four shots of the lead.

Several teams went low in the easier better-ball format. The teams of Brice Garnett-Chesson Hadley, Billy Horschel-Scott Piercy and Jason Dufner-Pat Perez all shot 61s to jump into contention.

The format switches to alternate shot for the final round.
