Johnson cool in Sony Open

Two-time major winner Zach Johnson rolled in a five-foot birdie putt at 18 on Thursday to seize a share of the firstround lead at the US PGA Tour Sony Open in Hawaii.

Johnson, the 2009 winner at Waialae in Honolulu, had seven birdies in his sevenunder 63, joining early pacesetter Chris Kirk atop the leaderboard in the US PGA Tour’s first full-field event of 2018.

Kirk, a four-time winner on the US tour, nabbed five of his seven birdies on the back nine. He had a look at eagle on the par-five 18th, where he holed a two-footer for birdie.
