Nick Watney and Kevin Na share the 54-hole lead at the Justin Timberlake Shriners Hospitals for Children Open. The duo, tied at 17 under, will be joined by Robert Garrigus (-16) in the final grouping Sunday at 2 p.m. ET (11 a.m. local time). Watney, a Vegas-area resident, birdied five of his last six holes Saturday as he made a late surge to the top of the leaderboard. Na did most of his damage on the more difficult front nine, managing just one birdie on the back nine as he shot a 5-under 66. Joining Garrigus one shot off the pace will be Kris Blanks. Two back are Tommy Gainey, Paul Goydos and Tim Herron. The six players tied with, or within two shots of Watney entering the final round, have a combined total of six PGA TOUR victories -- four belonging to Herron and two for Goydos. Watney has four, including two this year, as he rebounds from missed opportunities in the PGA TOUR Playoffs for the FedExCup. The Regular Season points leader posted just one top-10 finish in the four Playoffs events, but has wasted no time coming back into form.
