The PGA Tour’s hottest player at the close of 2013 didn’t miss a beat in opening the new year, as Zach Johnson recovered from a disappointing third-round 74 by firing a closing 66 to win the season-opening Hyundai Tournment of Champions in Hawaii.  After taking a strong three-shot lead at the halfway mark, Johnson struggled to get anything going in the third round, posting two late bogeys en route to the 74 which left him two in arrears of Dustin Johnson, Jordan Spieth and Webb Simpson.  But in the scheduled Monday finale, the 37-year-old from Cedar Rapids, Iowa methodically took apart the par-73 Plantation Course, eventually pulling away from a crowded list of pursuers first by birdieing the 12th, then by adding three straight birdies at holes 14-16.  Among the overnight leaders, only Spieth remained in serious contention, holding the lead prior to Johnson’s back nine explosion, then carding late birdies at the 17th and 18th to make the final margin of victory only one.  Third place was shared by Kevin Streelman (who closed with 67) and the 2012 U.S. Open champion Simpson, who carded early Monday bogeys at the 3rd and 4th to blow himself from contention before adding five subsequent birdies to close with 70.  Defending champion Dustin Johnson, meanwhile, opened with bogeys at the 1st and 2nd, then largely buried his hopes with one more bogey at the par-4 6th before ultimately tying for sixth with a closing 73.
