Reed, with eagles on the par-5 13th and 15th holes, shot 67 and stayed in first place for a second day.
He curled in a 14-foot eagle putt at the 13th, then saw his chip at 15 hit the green and race toward the hole, striking the pin and dropping in. Spieth missed the opportunity to be part of the contenders for the title after shooting for a 1-under-par Round 3.
Three of the last four winners at Augusta were ahead at the halfway stage and Reed calmly moved clear again with his fifth run of three consecutive birdies this week. McIlroy would be in the lead if he were putting better. He totally fell apart after that, playing the last nine holes at 7 over to finish with an 80.
After his final stroke on a soggy Saturday, he delivered an emphatic pump of the fist.
McIlroy has plenty on him, too.
This is the fourth straight year that he's arrived at Augusta National looking to complete the career Grand Slam - a feat accomplished by only five of the game's greatest players.
It was just after 8 a.m. and all the very best spots to view the holes named Dogwood, Golden Bell and Azalea were gone. Henrik Stenson was in third at 5-under.
Jon Rahm was the only other golfer to finish double digits under par, placing in fourth at 11-under for the tournament. His errant ways left him starting a lot sooner than expected Sunday and finishing shortly after the leaders teed off.
The 40-year-old Englishman has ripped off four birdies and an eagle over five holes on the back side, pushing his score to 9 under for the final day. Woods's final-round red and black became a signature look.
While it hasn't shown this week, the Masters will likely be Woods' best shot at winning another major championship, something he hasn't done since hobbling to a playoff victory at the 2008 U.S. Open.
Masters Tournament 2018Dates: April 5-8. He was 102nd after a tie for 17th at Augusta National in 2015.
Besides, it's stroke play.
And then last summer, Ghim was 2 up on Doc Redman with two holes to play in the final of the U.S. Amateur.
The four-time green jacket victor was on course to reach the level-par target he set himself at the end of round three after reaching four under through 17 on Sunday, with the help of a brilliant eagle at the 15th.
Oh, and yeah by the way - if Spieth is able to pull this off, it'll be the biggest Masters comeback in history. The cut is for the top 50 and ties and anyone within 10 shots of the lead.
After a three week break, Woods will crank it up for the Players Championship in a month. From there, disaster: a wayward drive off the 10 tee, an utter collapse around the corner, and a dejected manner on the 13 tee. With the way the back nine was playing today, the wheels could have come off there. The four-time Masters champion had three birdies in the opening round, two in the second and three in the third.
After three top-12 finishes this year, Woods had climbed to 103rd in the rankings heading into the Masters. He can birdie from distance or set up for the par - either will win him the Masters and that green blazer.
But Reed, 27, has never been rattled by whispers in clubhouses and embraced the roar on a flawless Georgia Sunday to give the 81st Masters yet another member entry to the champions locker room. Exceptions: Zach Johnson (2007), Charl Schwartzel (2011), Bubba Watson (2012), Adam Scott (2013) and Danny Willett (2016).
Four-time Masters victor Tiger Woods was left spinning his wheels on Moving Day. Burke was eight behind Ken Venturi through three rounds.
He came up short of the 63 shared by Nick Price and Greg Norman. He has won five PGA Tour titles, but he's 0 for 16 in majors. Tiger Woods is out of contention at 4 over entering the last round.
