Spieth went round in a three-under 68, with four birdies and a bogey, with a third American, Derek Ernst, on seven under following a 69.

Sean O'Hair was three shots off the pace in fourth place after shooting 69 ahead of a group of three on five under, Patrick Reed, Matt Kuchar and Henrik Stenson.

Scotland's Russell Knox is in a tie for 10th on three under after a 70 while Ian Poulter crashed completely out of contention, carding a four-over 75 to slip back to level par.
