Johnson, Kirk share Sony Open lead after Spieth stumbles late
HONOLULU, HI - JANUARY 11: Zach Johnson of the United States prepares to play his shot from the 17th tee during round one of the Sony Open In Hawaii at Waialae Country Club on January 11, 2018 in Honolulu, Hawaii.

Zach Johnson birdied three of his final six holes Thursday to fire a 7-under-par 63, giving him a share of the opening-round lead with Chris Kirk at the Sony Open in Hawaii.

Vaughn Taylor, Kyle Stanley, Talor Gooch, and Brian Harman sit one back of the co-leaders at 6-under par, while Peter Malnati, Daisuke Kataoka, and Matt Every are tied for seventh at 5-under.

Jordan Spieth was cruising through 16 holes at 4-under par on his round, but made a mess of the par-4 eighth - his 17th hole - with a quadruple-bogey eight. Spieth, however, rebounded with a birdie on the final hole to post a 1-under-par 69.

Defending champion Justin Thomas was steady all day, carding three birdies and no bogeys for a 3-under-par 67.
