Ryan Palmer and Tony Finau are tied for the lead at the halfway stage of the Memorial Tournament, where 15-time major champion Tiger Woods narrowly made the cut.
Palmer carded a four-under-par 68 to join fellow American Finau in a share of the one-stroke lead following Friday's second round in Dublin, Ohio.
Finau was the outright leader when day two started, but a second-round 69 saw him head into the weekend with company at nine under through 36 holes at Muirfield Village.
Spanish star Jon Rahm is a shot off the pace after a five-under-par 67, while Gary Woodland (70), Chez Reavie (67) and Luke List (68) are tied for fourth at six under.
After opening with a 73, former world number one Jason Day posted a 66 to catapult himself into outright seventh position – four shots behind Palmer and Finau.
Back-to-back 70s has Jordan Spieth four under at the halfway point, one stroke ahead of another American star – Justin Thomas, who used a five-under-par 67 to climb 43 positions into a tie for 16th.
World number one Rory McIlroy's struggles continued after an even-par 72 saw him slip seven shots off the pace.
McIlroy is yet to finish in the top 10 of a PGA Tour tournament since golf resumed in June amid the coronavirus pandemic, and a double bogey and four bogeys left the Northern Irishman tied for 21st.
As for Woods, the American superstar barely survived to prolong his PGA comeback into the weekend on Friday.

He has never missed the cut at the @MemorialGolf and needs a birdie at the last for a chance.

Woods – in action for the first time since February – made a decent start but his second round was far more concerning amid back problems.
The 44-year-old, who opened the event with a 71, signed for a four-over-par 76 to close the day three over, just one stroke above the cut line.
Three bogeys from his first nine holes left Woods in trouble, but the five-time Memorial Tournament winner rallied after the turn by birdieing two of his final three holes.
While the likes of Brooks Koepka (75), Patrick Reed (76) and Phil Mickelson (74) managed to make the cut, Rickie Fowler (68), Justin Rose (76) and Bryson DeChambeau (76) failed to qualify for the weekend.
