Tiger Woods needed something special on Sunday in Round 4 of the 2018 Memorial Tournament to have a real chance at picking up his sixth win at Muirfield Village.
Among those three off the lead were Hideki Matsuyama (71), who earned his first PGA Tour title at the Memorial three years ago, and Jason Day, a former world No. 1 who is a member at Muirfield Village and has never come close to winning.
South Korea's An Byeong-hun was in fifth at 12-under 204, two strokes ahead of Englishman Justin Rose (69), who is looking for his second straight PGA Tour win after his victory at the Fort Worth Invitational in Texas. He made bogey for a 70 and still got into a playoff, but he was eliminated on the first extra hole when his approach from deep rough and the ball well above his feet squirted to the right, leading to a bogey.
Rory McIlroy was also in the group at 11 under as he followed his superb third-round 64 with a five-birdie 69, while Tiger Woods stumbled home in 38 and endured another frustrating day on the greens as a 72 saw him slide 16 places down the leaderboard on nine-under par.
And then he sat out a weather delay that lasted just under 90 minutes, and he missed four putts under 7 feet the rest of the way. DeChambeau pulled within one shot with a birdie on the par-5 11, and he took the lead with a two-shot swing on the next hole with a birdie as Cantlay made bogey from the bunker.
Woods will attempt to equal the tournament's largest 54-hole comeback at five shots off the pace, but will no doubt draw from starting the final round four shots back during his 2012 Memorial victory.More news: Kim Jong-un sends right-hand man to USA for pre-summit talks

"I can't believe I did it", DeChambeau said. "I've got a good feel for what I'm doing".
The five-time Memorial victor missed a short birdie on 14 but gained a share of the lead at 11-under with a birdie at 15.
This is the third time this year Woods has gone into the final round within five shots of the lead. "This is probably the highest score I could have shot". I just didn't really play well. What if, by the time the putter cooperates, the short-range makes are for bogeys instead of birdies? DeChambeau rolled in a 20-foot birdie on the par-3 16th, and he hit 9-iron to 5 feet on the toughest hole, the 18th.
Rose, four adrift going into the final round, had two birdies in his first three holes before dropping two shots on the back nine.
"It's a strong field on the leader-board and I think everybody's going to go out there and try to make the most birdies possible", Niemann said.
