Turnesa still leading

American Marc Turnesa regained the lead in the Justin Timberlake Shriners Hospitals for Children Open but compatriot Chris DiMarco moved into contention on Saturday.

DiMarco carded a round of 63 to leap to 20-under, one behind Turnesa who shot 69 in his third round at TPC Summerlin in Las Vegas.

Former Masters champion Zach Johnson, who won the Valero Open last week, is just two off the lead after a round of 70, with Matt Kuchar and Chris Stroud also on 19 under.

Mark Hensby remains the best placed Australian in a tie for 21st place, after his four-under par round took him to 14-under overall.

Nick Flanagan recovered from his disappointing second round to also post a four-under to take him back up to 10-under, while Jason Day also shot a 68 to be in a tie for 56th.

Matthew Goggin is equal with Flanagan in a tie for 36th at 10-under, while Peter Lonard (nine-under) and Matt Jones (eight-under) are languishing at the bottom of the leaderboard.
