Rory McIlroy and Dustin Johnson kept themselves well within a shout of second respective US Open successes with excellent third rounds on Saturday.
Johnson put in his best performance of this year's event at Torrey Pines, carding a 68 which moved the world number one to one under par, and he would surely have been even closer to the leaders if not for a dismal loss of form on the back nine on Friday.
"I feel like I'm swinging really well. I didn't drive it on the fairway enough but I felt like I managed the game pretty well. I rolled the putter really nicely today and made a lot of clutch par putts, which is what you've got to do in the US Open," Johnson told Sky Sports.
"When I was on the fairway I felt like I played pretty well, my irons were good and I'm controlling my distance – I'm just not getting enough shots from the fairway.
"I felt like they did a really good job of setting the course up - if you drive it on the fairway, you can attack the golf course and it's been like that all week. There's a few holes obviously where you will take a four and run but for the most part the way they set it up today, you can attack it."
McIlroy, meanwhile, went one better, finishing on 67 for the round to keep his chances firmly alive. The 2011 champion's birdie on the 18th ensured he was the clubhouse leader at three under.
Russell Henley, meanwhile, reached the turn with a two-shot lead over Richard Bland.
The overnight leader reached the front of the ninth in two shots, yet missed his eagle attempt and subsequently had to settle for a three-out par, whereas Henley snatched a birdie.
However, Henley then dropped a shot on the 10th, immediately cancelling out his own advantage.
Bryson DeChambeau is also in the hunt, with the defending champion T3 with McIlroy, Jon Rahm and Matthew Wolff.
Paul Casey had looked sharp earlier in the day, yet bogeys on the 16th and 17th meant he had to settle for 67, and heads into round four on par.
