Zach Johnson holds off Adam Scott's charge to win Tournament of Champions in Hawaii Zach Johnson drives off the first tee at the Tournament of Champions. ADAM Scott's last hole bogey proved expensive as Zach Johnson claimed an impressive victory at the Tournament of Champions in Hawaii. Johnson, the 2007 Masters champion, fired a bogey-free seven-under-par 66 to win by one stroke from fellow American Jordan Spieth (69) at 19-under 273 on the Plantation Course at Kapalua. Australia's world No.2 Scott started the final round four off the pace but surged within one shot of the lead with three birdies then an eagle on the par 5 15th. However the Masters champion made bogey on the par 5 18th to finish with a 69 and slip into a share of sixth place on 278. Johnson confirmed his status as one of the hottest players in world golf as he claimed his 11th US PGA Tour title. Adam Scott finished in a tie for sixth. It was Johnson's third win in his past six starts, and his eighth top-10 finish in his past 11 official US tour events dating back to July's John Deere Classic. Since his rookie year in 2004, only Tiger Woods, Phil Mickelson and Vijay Singh have won more.
