New Zealand golfer Danny Lee remains firmly in title contention at the latest PGA tour event in Texas despite slipping off the top of the leaderboard.
Lee shot a birdie on the last hole at the Dean and Deluca Invitational in Fort Worth, leaving him seven under, two shots off the leader Web Simpson.
Lee started the third round in a tie for first but carded a one under par 69 to drop to a share of second alongside Englishman Paul Casey.
Americans Stewart Cink and Kevin Kisner were three off the pace, while defending champion Jordan Spieth and Masters champion Sergio Garcia were five behind.
Spieth played the final seven-plus holes with a stand-in caddie after his regular looper Michael Greller fell ill in the oppressive heat and humidity. Trainer Damon Goddard carried the bag the rest of the way.
"Michael went down with heat exhaustion, when we were walking down the 11th he said 'this is my last hole.' I thought he was acting a little strange, a little quiet." Spieth said.
