Zurich Classic leaders Blixt and Smith move clear

Updated: 

Jonas Blixt and Cameron Smith closed in on the Zurich Classic of New Orleans title after extending their lead to four strokes.

Overnight leaders in the team-play format at this year's event, Blixt and Smith widened their advantage over two other duos thanks to Saturday's alternate-shot third-round 68.

After hitting the front during Friday's four-ball (best ball) play, the PGA Tour tournament returned to foursomes on the weekend and the leading pair starred in blustery conditions at TPC of Louisiana.

Swede Blixt and Australian team-mate Smith posted two birdies on the front nine and as many following the turn to be 19 under through 54 holes.

Kevin Kisner/Scott Brown and Charley Hoffman/Nick Watney are the pair's nearest challengers.

Kisner and Brown carded a five-under-par 67, while Hoffman and Watney scored a 69.

Former world number one Jordan Spieth and Ryan Palmer are five shots off the pace heading into Sunday's final round, which will be four-ball.

After consecutive 66s, two-time major champion Spieth and fellow American Palmer could only manage a two-under 70 having recorded four birdies and two bogeys.

Brian Stuard/Chris Stroud (71) are 13 under, while Kelly Kraft/Kevin Tway (70) and Angel Cabrera/Julian Etulain (71) are a shot behind.
