MARANA, Ariz. -- Shane Lowry found it difficult to come down from the high of knocking off top overall seed Rory McIlroy in Thursday's first round. Lots of phone calls, lots of text messages and finding it difficult to sleep.
But once Friday morning arrived, Lowry refocused, eventually knocking off Carl Pettersson 6 and 5 in the second round.
Lowry has now advanced farther than any previous 64th seed has in this tournament. The previous three times that the last seed knocked off the top seed were followed by second-round losses.
"To lose in the second round is not what I want coming here this week," the Irishman said. "I wanted to go on. I feel like I could potentially do very well in this tournament."
He certainly played very well Friday, a bogey-free 5 under through his 13 holes.
Pettersson, who earlier in the day finished the completion of his first-round win over Rickie Fowler, didn't play poorly but couldn't keep up. He parred his first eight holes and found himself 3 down at that point. He dropped the ninth hole with a bogey and suffered another bogey at the 12th. He never won a hole.
SCORECARD STATS: Lowry carded five birdies and no bogeys. Pettersson carded one birdie and two bogeys.
HOLES WON: Lowry won six holes. Pettersson did not win a hole.
NEXT OPPONENT: Lowry plays the Alexander Noren-Graeme McDowell winner in the third round of the Jones bracket.
MARANA, Ariz. -- Fredrik Jacobson spent Thursday night practicing his putting in his hotel room. It lasted two hours. Maybe three.
The practice is paying off.
The 12th-seeded Jacobson posted another solid round to knock off 13th-seeded Marcus Fraser of Australia, 4 and 3, in the second round.
Jacobson reached the third round for the second time in four starts here. The last time he advanced this far, he lost to Tiger Woods. But now Woods is out and Jacobson is still alive and riding momentum of some good play recently.
"Every match is tough out there," Jacobson said. "You're just happy to sneak by and try to get through one at a time. But really excited to be in the third round."
Jacobson won the first two holes, including a birdie at the par-5 second. He stumbled with a bogey at the fourth, but won the next hole when Fraser bogeyed.
The Swede went 3 up with a birdie at the par-5 eighth. He bogeyed the 13th but posted consecutive birdies on the final two holes to close out the match.
Fraser failed to birdie a single hole Friday.
SCORECARD STATS: Jacobson carded four birdies and two bogeys. Fraser carded no birdies and two bogeys.
HOLES WON: Jacobson won six holes. Fraser won two holes.
NEXT OPPONENT: Jacobson plays Robert Garrigus in the third round of the Hogan bracket.
MARANA, Ariz. -- This match was a tight one with Jason Day getting to 2 up for just one hole. Otherwise, the Aussie was 1 up for eight holes and Russell Henley, who was making his Accenture Match Play Championship debut, held the same advantage for six.
Day got the edge early when he birdied the second hole. But two of his three bogeys, which came at the fifth and sixth holes, put Henley, who birdied No. 6, on top.
The two halved the eighth hole with birdies so Henley was 1 up at the turn. Day quickly turned the tide, though, when he won three straight -- starting with a birdie at the 12th, followed by a par at No. 11 and another birdie at the 13th.
That 2-up lead was short-lived, though, as Henley made a 7-footer for birdie at the 14th. The rookie, who won the Sony Open in Hawaii early this year, then made a 14-footer at the 18th hole to extend the match only to lose to Day's 9-footer on the first extra hole after missing one from 13 feet of his own.
"I think Russell only missed one green today, which was very, very frustrating on my side, because he hit it great, so that means you have to make birdie," Day said. "I just did enough today to win. He was very clutch on 18 to actually hole the putt and get it back to all square. And fortunately I hit a nice tight one into the 19th hole, and he missed his birdie putt and I holed one, which was nice.
SCORECARD STATS: Day made five birdies and three bogeys in 19 holes. Henley made four birdies and two bogeys.
HOLES WON: Day won five holes. Henley won four holes.
NEXT OPPONENT: Bubba Watson, who beat Jim Furyk on the 22nd hole.
MARANA, Ariz. -- Big-hitting American Robert Garrigus, a No. 9 seed, upset Louis Oosthuizen, the top seed in the Hogan bracket, 3 and 2 in the second round.
With the earlier loss of Luke Donald to Scott Piercy, all four No. 1 seeds have now been eliminated. Rory McIlroy and Tiger Woods lost in the first round.
Garrigus said he never felt like an underdog to Oosthuizen, despite the seeding.
"I felt like I was playing better than anybody coming in here, so whatever seed it was didn't matter," Garrigus said.
Garrigus indeed has been putting well this week, having needed just 47 puttsin the first two rounds. On Friday, he had eight birdies on his round, with four birdies putts coming between 7 and 11 feet. He now has 14 birdies through the first two rounds.
"I looked at all the guys in my bracket and I was like, 'I can beat him, I can beat him and I can beat him,' " Garrigus said. "If I'm putting well, I'm going to be hard to beat."
Garrigus won the first two hole but the match was all square through eight, as Oosthuizen played a bogey-free 2 under for the first eight holes.
But from there, Garrigus was a bogey-free 4 under in the final eight holes and Oosthuizen could not keep pace.
SCORECARD STATS: Garrigus carded eight birdies and two bogeys. Oosthuizen carded four birdies and one bogey.
HOLES WON: Garrigus won five holes. Oosthuizen won two holes.
NEXT OPPONENT: Garrigus plays Fredrik Jacobson in the third round of the Hogan bracket.
MARANA, Ariz. -- Defending champion Hunter Mahan, a No. 6 seed, beat Richard Sterne of South Africa, 4 and 3, in the second round.
Mahan has now won 10 of his last 11 matches at Dove Mountain dating back to 2011.
"Confidence is high," Mahan said. "I know I can play this place well, and I know I can beat anybody on any given day."
Mahan got off to a quick start Friday with birdies on his first two holes. But he lost the fifth and sixth holes. The match was all square after Mahan's second bogey of the day at the ninth hole.
But then Sterne, a 14th seed, suffered bogeys at the 10th and 11th holes, and Mahan followed that with a birdie at the par-3 12th when his tee shot landed inside of 7 feet.
Mahan then won his fourth consecutive hole at the par-5 13th when Sterne conceded a 10-1/2 foot eagle putt. That put Mahan 4 up.
"I was able to put the pressure kind of on my opponent once I got going on the back nine with the first four holes there," Mahan said. "That was obviously key and important."
SCORECARD STATS: Mahan carded four birdies, two bogeys and a had a conceded eagle. Sterne carded three birdies and three bogeys.
HOLES WON: Mahan won six holes. Sterne won two holes.
NEXT OPPONENT: Mahan plays Martin Kaymer in the third round of the Player bracket.
MARANA, Ariz. -- Martin Kaymer, who made the clinching putt in the Ryder Cup, never trailed in his match with Rafael Cabrera Bello, who had beaten him in the Volvo World Matchplay.
"It was a tough match," Kaymer said. "It's never easy against him. But he was very unfortunate with some putts today. He had a few chances to go back to all square, especially on the back nine, but I played very solidly. Hit a lot of fairways, hit a lot of greens, hit good putts. Very similar to yesterday."
He took the early lead with a two-putt birdie at the par-5 second hole but gave that back with a bogey at the fourth. The German managed to head to the back nine 2 up, though, after a birdie at the seventh and a par to the Spaniard's bogey at No. 9.
Kaymer made an 8-footer for his final birdie of the day at the 11th hole to go 3 up. Cabrera Bello did cut into Kaymer's lead at the next par 5 but the two halved the next four holes with pars to send the German to the third round for the third straight year.
Kaymer reached the championship match in 2010, losing to Luke Donald 3 and 2, and was eliminated in the third round a year ago. He has a home in Scottsdale, which is about 90 minutes away, and is very familiar with desert golf.
"So this is golf that I play very often," said Kaymer, who joined the PGA TOUR for the first time this year. "I don't mind playing here. I like it, it's just really nice. That's why I always play very well in the Middle East, very similar conditions to here."
SCORECARD STATS: Kaymer made three birdies and two bogeys. Cabrera Bello made two birdies and two bogeys.
HOLES WON: Kaymer won four holes. Cabrera Bello won two holes.
NEXT OPPONENT: Hunter Mahan, the defending champion, who beat Richard Sterne 4 and 3.
MARANA, Ariz. -- England's Ian Poulter, who won the World Golf Championships-Accenture Match Play Championship in 2010, looks in terrific form again at Dove Mountain after dispatching American Bo Van Pelt, 3 and 1, in the second round.
Poulter, a No. 3 seed, had a bogey-free round with six birdies and another birdie putt conceded.
"I played the type of golf that's going to be tough to beat," Poulter said. "Very pleased how I took some mistakes from yesterday and kept a very clean round."
Having taken the last six weeks off prior to this week, Poulter said he "couldn't feel any fresher or fitter."
Van Pelt, a No. 6 seed, grabbed the early lead with his second birdie of the day at the par-4 fourth. But he suffered consecutive bogeys at the sixth and seventh holes to fall 1 down.
Poulter pulled away from there. He birdied three of the next four holes to move to 4 up. Van Pelt responded by winning the next two holes, including the par-5 13th when Poulter settled for par after just coming up short of the green in two.
"Only mistake I made was I 3-putted from 100 feet," Poulter said before adding, "Shucks."
Both players birdied the par-4 15th, then Van Pelt conceded the 17th hole and the match after missing his 12-foot birdie putt.
SCORECARD STATS: Poulter carded six birdies, had another birdie putt conceded and no bogeys. Van Pelt carded six birdies and three bogeys.
HOLES WON: Poulter won six holes. Van Pelt won three holes.
NEXT OPPONENT: Poulter plays Tim Clark in the third round of the Snead bracket.
MARANA, Ariz. -- Maybe that double bogey from the desert at the first hole set the tone for what wasn't going to be Luke Donald's day. Scott Piercy was just too strong and too fearless as he took down the top seed in the Sam Snead bracket.
Piercy was 3 up after three holes thanks to Donald's double, his own birdie and another bogey from the Englishman. Piercy holed a shot from 228 yards for an eagle at the fifh hole to go 4 up, then won the eighth and ninth with birdie putts of 25 inches and 5 feet to head to the back nine in complete command.
A final birdie, this one on a 4-foot putt, ended the proceedings at the 12th hole. Piercy's upset win over the 2011 Accenture Match Play Championship winner was the most lopsided result of the week to date.
"I actually feel really relaxed out there," Piercy said. "Me and Luke's game are a lot different, and I feel like if I get things going, I've got a good chance of beating him. I played well, and he was off a little bit. That's why it looked so one-sided."
And make no mistake, Piercy, playing in just his second match at the Accenture Match Play Championship, was hitting on all cylinders. He hit 7 of 9 fairways, 11 of 12 greens in regulation and used just 17 putts.
"Scott played very well, I played just very average," Donald said. " I need to drive it well around this course. There's a few forced carries out there, and probably didn't drive it well enough today to put any pressure on Scott. But he was 7 under through 12 and just playing extremely solid, didn't give me really a look.
"I had a few opportunities on the greens, but for whatever reason I was just not making the putts today, and hence I'm going home."
SCORECARD STATS: Piercy made five birdies and an eagle over 12 holes. Donald made two birdies, two bogeys and one double bogey.
HOLES WON: Piercy won seven holes. Donald did not win any.
NEXT OPPONENT: The winner of the match between Steve Stricker and Nick Watney.
MARANA, Ariz. -- South African Tim Clark, a No. 15 seed, defeated Denmark's Thorbjorn Olesen, a No. 10 seed, in the second round at Dove Mountain.
Clark hit 14 of 16 greens and said after the match, "That's the best I've probably hit the ball all year, to be honest with you."
All square after six holes, Clark pulled away starting at the par-4 seventh when he rolled in a 13-foot birdie putt. He followed with a birdie at the par-5 eighth while Olesen found trouble off the tee. Olesen hit a wayward approach shot at the par-4 10th and eventually conceded the hole, putting him 3 down.
Olesen bounced back, stringing together three straight birdies. But he could only win one hole.
Clark was 2 up going into the 14th and added to his advantage with a great approach shot within 5 feet. Olesen had his own birdie attempt from inside 10 feet but couldn't hole it.
Not pleased with his game in the first round, Clark was happy to improve his performance Friday. "It's nice to have that turnaround this quickly," Clark said
Clark has now reached the third round for his third consecutive start in this event.
SCORECARD STATS: Clark carded five birdies and one bogey, Olesen carded three birdies and one bogey.
HOLES WON: Clark won five holes. Olesen won two holes.
NEXT OPPONENT: Clark plays Ian Poulter in the third round of the Snead bracket.
