Louis Oosthuizen and Charl Schwartzel lead the Zurich Classic after third round

Louis Oosthuizen and Charl Schwartzel combined forces to shoot 9-under-par in the third round of the Zurich Classic of New Orleans to lead on 19-under-par heading into Sunday. 

The South African team made three birdies on the front nine, but charged on the back nine with six birdies to post their second 63 of the week in the fourball better-ball discipline.

The pair, with two major titles between them, only managed a 1-under-par 71 on Friday at TPC Louisiana and began the third round three shots behind the leaders. 

Cameron Smith and Marc Leishman sit in tied second place alongside Tony Finau and Cameron Champ as both teams finished on 18-under-par on Saturday.

The Australian pair both finished in the top 10 at The Masters and much like the leaders, they shot their second 63 of the week in the fourball better-ball format to stay in the hunt.

Finau and Champ shared the lead with Viktor Hovland and Kris Ventura on 13-under-par after two rounds, but the American team didn't quite match their form of the first round.

Although they had opportunities to go lower, the big-hitting pair scored 5-under-par on Saturday to fall to one shot behind Oosthuizen and Schwartzel in tied second place.

Bubba Watson and Scottie Scheffler may not have planned to be together this week, but they shot their third successive round in the 60's to finish on 17-under-par for the tournament.

They shot a 6-under-par 66 to join overnight co-leaders Hovland and Ventura in tied fourth place. The Norwegian pair made a frustrating bogey on the par-3 9th hole and shot 4-under-par to remain within two of the leaders.

There were some superb scores on Saturday in the fourball better-ball format, as 11 out of the top 14 teams on the leaderboard shot 8-under-par or better in their third round.
