The shocking setback for McIlroy extended a disappointing start to the year for a player expected to become one of the sport's dominant figures. He missed the cut in his only other appearance of the season.
The opening round began on Wednesday, but was suspended due to a heavy snowfall. The second round will be played Thursday and the third round will get underway.
Among Thursday's surprises were a 1-up victory for PGA Tour rookie Russell Henley over former Masters champion Charl Schwartzel, Alexander Noren's 6-and-4 demolition of Dustin Johnson and the 1-up win for Richard Sterne over Jason Dufner.
Lowry chipped in for birdies at both the 11th and 12th holes of his match with McIlroy and then took a 2-up lead at the par-5 13th with an eagle. McIlroy also suffered three bogeys and a double bogey during the match.
The Woods-Howell confrontation was all square with four holes to play, but Howell birdied both the 15th and 16th to seize the advantage.
Devils rally to defeat Washington
WASHINGTON, Feb. 21 (UPI) -- Third-period goals by Andrei Loktionov and Ilya Kovalchuk Thursday rallied New Jersey to a 3-2 victory over Washington.
The Devils, who had lost their previous two games, moved two points in front of Pittsburgh for the lead in the Atlantic Division.
Martin Brodeur needed to make just 17 saves to get the victory, the 664th of his career. He has an 8-4 record this year with two of those losses coming in overtime.
New Jersey faced a 2-1 deficit heading into the final period, but Loktionov tied it 9:19 into the stanza with a slap shot that produced his first goal of the season.
Kovalchuk scored the game-winner on the power play with 8:20 to play.
Patrik Elias delivered the other New Jersey goal shorthanded midway through the second period that forged a 1-1 tie. Mike Ribeiro temporarily put Washington in front at 2-1 with 7:20 to go in the first.
Braden Holtby stopped 34-of-37 shots in taking the loss.
