Jordan Spieth makes robust defence when questioned about possible rules violation

Spieth had a 10-minute discussion with a rules official before taking a drop.

World number three Jordan Spieth was surprised to face questions about a possible rules violation after a second round of 67 in the US PGA Championship.

Spieth carded five birdies and two bogeys at Baltusrol, the last of which came after a wild drive which finished in casual water on a cart path and resulted in a 10-minute discussion with rules official Brad Gregory before taking a drop.
