Group 1: Dustin Johnson (1) def. Jimmy Walker (18), 5 and 3: The world's best is playing like it. He still has yet to trail after a single hole this week and was 6 up through seven holes today. He went 3-0-0. Walker went 1-2-0.
Group 1: Martin Kaymer (41) def. Webb Simpson (58), 3 and 2: Simpson double bogeyed the first hole and never recovered. He went 0-3-0 this week. Kaymer was a respectable 2-1-0. But no one in the group could match DJ.
Group 2: Soren Kjeldsen (62) def. Gary Woodland (33), conceded: Woodland withdrew prior to the start of Day 2, citing a family emergency. The victory moved Kjledsen to 3-0-0 in pool play and also moved him into Round of 16 match play.
Group 2: Rory McIlroy (2) vs. Emiliano Grillo (26), halved: No one won in a match in which neither could advance. McIlroy went 2-1-0. Grillo was 0-2-1.
Group 3: Marc Leishman (28) def. Jason Day (3), conceded: Day withdrew from the event on Wednesday to be with his mother, who is battling lung cancer and underwent surgery on Friday. Leishman moved to 2-1-0.
Group 3: Lee Westwood (43) def. Pat Perez (56), 2 and 1: All square though 11 holes, Westwood won Nos. 12 and 13, and then held on for the win. Both men finished at 2-1-0 and joined Leishman in a stroke-play, sudden-death playoff.
Playoff: After a trio of pars at the first, Leishman birdied the second hole from 12 feet to advance.
Group 4: Louis Oosthuizen (23) def. Hideki Matsuyama (4), 6 and 4: It was an awful week for Matsuyama, who went 0-2-1. Oosthuizen went 2-1-0.
Group 4: Ross Fisher (47) def. Jim Furyk (51), 4 and 2: Despite a Furyk fairway hole out, Fisher got the better of the U.S. Ryder Cup captain. Fisher went 2-1-0 to advance to a playoff with Oosthuizen.
Playoff: Fisher birdied the second extra hole to knock out last year's runner-up.
Group 5: Hideto Tanihara (54) def. Yuta Ikeda (37), 3 and 1: Tanihara defeated his countryman and advanced to the Round of 16, having defeated Jordan Spieth on Day 1.
Group 5: Jordan Spieth (5) vs. Ryan Moore (32), halved: Once Tanihara finished out ahead of him, this match was meaningless for Spieth. He finished 1-1-1, while Moore halved all three of his matches.
Group 6: Matthew Fitzpatrick (27) def. Justin Thomas (6), 2 and 1: Fitzpatrick was in trouble through 13 holes, but birdied Nos. 14-17 to turn a 2-down deficit into a 2-and-1 win. Thomas needed to win to have a chance to advance, but he's now out. Fitzpatrick finished 2-1-0.
Group 6: Chris Wood (49) def. Kevin Na (46), 2 and 1: Na was in great shape to advance, leading 4 up through seven holes. But he then fell apart, losing seven of his next eight. He finished at 2-1-0. Wood at 1-2-0.
Playoff: Na nearly holed his approach shot on the first hole of sudden death. His birdie won the playoff and pushed him through to pool play.
Group 7: Jon Rahm (21) def. Sergio Garcia (7), 6 and 4: The score says it all as Rahm ran roughshod over his Spanish compatriot. Rahm won the group with a perfect 3-0-0 record.
Group 7: Kevin Chappell (38) def. Shane Lowry (53), 1 up: Chappell won No. 16 with a birdie and No. 18 with a par to get his first win of the week. He finished 1-2-0. Lowry was 0-2-1.
Group 8: Alex Noren (8) def. Francesco Molinari (25), conceded: Molinari lost, 5 and 3, to Thongchai Jaidee on Thursday and then withdrew from the tournament, citing a wrist injury. At 0-2-0, he was already elimated from match play. Noren, at 3-0-0, advances to the weekend.
Group 8: Bernd Wiesberger (36) def. Thongchai Jaidee (57), 1 up: Strong showing for Wiesberger, who birdied his final two holes to turn a 1-down deficit into a victory. He went 2-1-0 on the week. Jaidee was 1-2-0.
Group 9: Brooks Koepka (20) def. Patrick Reed (9), 1 up: Koepka had not been playing well. Reed was a Ryder Cup hero. But it's the former who goes 3-0-0 and the latter who fails to win a match, going 0-2-1.
Group 9: Kevin Kisner (34) def. Jason Dufner (59), 2 and 1: With nothing to play for but pride (and FedEx Cup points!), Kisner prevailed. He went 2-1-0 this week. Dufner, 0-2-1.
Group 10: Rafa Cabrera Bello (22) def. Tyrrell Hatton (10), 2 and 1: The two were all square through 12 holes, before the Spaniard won Nos. 13 and 15. They both finished at 2-1-0.
Group 10: Charles Howell III (61) def. Jeung-Hun Wang (40), 2 and 1: Howell was in control throughout this match, never trailing. By finishing 2-1-0, he made it a three-man, stroke-play playoff.
Playoff: Howell won on the fourth extra hole. Hatton was eliminated on the first hole when he accidentally caused his ball to move and did not replace it before tapping it in. He was assessed a two-stroke penalty.
Group 11: Danny Willett (11) def. Russell Knox (17), 4 and 2: The top two seeds in the group had no chance of advancing. The Masters champ salvaged his week, sort of, with an easy win over the Scot. Both men finished 1-2-0.
Group 11: Bill Haas (42) def. K.T. Kim (64), 4 and 2: Kim just needed to halve this match in order to advance, but Haas pulled away on the back nine, making birdie on three of his final five holes. They both finished pool play 2-1-0 and headed to a sudden-death playoff.
Playoff: Haas chipped in on the second hole to stay alive and surived a couple of Kim misses, thereafter, to win. Haas eventually prevailed with a birdie on the sixth hole.
Group 12: Paul Casey (12) def. Charl Schwartzel (24), 4 and 3: Casey continued to show he's a match-play stalwart beating previously undefeated Schwartzel. Casey finished 3-0-0 and is off to single elimination.
Group 12: Joost Luiten (60) def. B.H. An (45), 1 up: In a battle of winless players, Luiten birdied the last to avoid the shutout.
Group 13: Bubba Watson (13) vs. Thomas Pieters (30), halved: Watson needed at least a half-point to advance and that's what he got. He was the only player in his group to get two wins.
Group 13: Jhonattan Vegas (55) vs. Scott Piercy (39), 3 and 1: Vegas had a good week, going 2-1-0. But it wasn't enough to top Bubba. Piercy, meanwhile, took the bagel, going 0-3-0.
Group 14: Phil Mickelson (14) def. J.B. Holmes (31), 6 and 5: Mickelson easily advanced through pool play, going 3-0-0. He only made two birdies on Friday, but throttled an off-form Holmes, who never won a hole and finished 0-2-1.
Group 14: Si-Woo Kim (63) def. Daniel Berger (35), 1 up: No one led by more than 1 up in this match, but it was Kim who finished with that advantage. Kim went 1-1-1 and Berger finished 1-2-0.
Group 15: Brandt Snedeker (19) def. Branden Grace (15), 5 and 4: The easy victory bumped Snedeker's record to 2-1-0, but he was still eliminated because of his loss to William McGirt on Day 1.
Group 15: William McGirt (48) def. Andy Sullivan (52), 1 up: McGirt capped off a perfect pool-play session, going 3-0-0. He advanced, while Sullivan lost all three of his matches this week.
Group 16: Matt Kuchar (16) def. Tommy Fleetwood (29), 4 and 2: The top seed in this group was only 1 up through 13 holes, but won Nos. 14-16 with birdies. He finished 1-1-1. Fleetwood went 0-2-1.
Group 16: Zach Johnson (44) def. Brendan Steele (50), 1 up: In the final match of the day, Johnson lost a 2-up lead with three to play, only to win the 18th with a par. He advanced to the Round of 16 with a 2-1-0 record. Steele went 1-1-1.
