Steve Stricker maintained his five-shot lead in the third round of the Tournament of Champions in Hawaii after a blistering four-birdie finish.
He started the round with the same lead but struggled early on and his competitors were able to make in roads into his lead. At one stage his advantage had been trimmed to just one shot before he regained control with his strong finish.
Stricker, the highest-ranked player in the elite field, is on 19-under par after three rounds of the event.
"It was a struggle today," Stricker said after recording five birdies and a bogey on the hilly Plantation Course. "Not a lot of good things happened but I stayed patient.
"I felt like things were going to turn my way coming in, and they did. It was a good finish and put me in a good position heading into tomorrow."
Defending champion Jonathan Byrd also struggled early on with two bogeys but recovered to shoot a 67 for a share of second place with fellow American Webb Simpson (69) and Scotland's Martin Laird (67).
Two more Americans, Bryce Molder (67) and Kevin Na (71), were tied for fifth at 11 under in the limited-field tournament.
Keep an eye out as well for Rory Sabbatini, whose third round 68 saw him jump into the top 10.
