Golf roundup: Another rough day for top 10

One day after Rory McIlroy and Tiger Woods went home, more top seeds followed Friday in the Match Play Championship until Masters champion Bubba Watson was the only seed from the top 10 remaining at Dove Mountain in Marana, Ariz.

And even that wasn’t easy.

Watson, the No. 8 seed, missed two straight putts from 5 feet that would have won the match before he finally put away Jim Furyk in 22 holes. It was the first time since this World Golf Championship event began in 1999 that only one top-10 seed was left after two rounds.

What does that mean?

‘‘Nothing,’’ Watson said. ‘‘This game . . . it’s a toss-up. You can’t really judge who’s going to win, or bet who’s going to win.’’

Luke Donald, the No. 3 seed who birdied his last two holes on Thursday to win his opening match, didn’t know what hit him Friday. Scott Piercy won the first three holes, then holed out from 221 yards with a 4-iron on the fifth hole and was on his way. He won, 7 and 6, to give Donald his worst loss in this event.

Fourth-seeded Louis Oosthuizen never led against Robert Garrigus, who closed him out on the 16th hole and sounded as though he had penciled himself into the final.

‘‘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.’ If I’m playing well and putting well, I’m going to be hard to beat,’’ he said.

He’ll find out Saturday morning against Jason Day, who overcame a clutch putt on the 18th hole to beat PGA Tour rookie Russell Henley on the 19th.

Justin Rose, the No. 5 seed, couldn’t keep up with Nicolas Colsaerts and lost, 4 and 2.

Shane Lowry earned a footnote in history at this 15-year-old tournament. After knocking out McIlroy on the 18th hole of the first round, the burly Irishman became the first No. 64 seed to advance to the third round. This wasn’t that difficult, as he seized control early and beat Carl Pettersson, 6 and 5.

Two more wins on Saturday and Lowry will qualify for the next WGC event at Doral in two weeks. Next up for Lowry is Graeme McDowell of Northern Ireland, who outlasted Alex Noren of Sweden in 20 holes.

The other giant killer, Charles Howell III, wasn’t so fortunate. Gonzalo Fernandez-Castano, who had to finish his 1-up win over Francesco Molinari in the morning, never lost a hole in a 6-and-5 win. Howell, one day after beating Woods, didn’t make a single birdie.

Defending champion Hunter Mahan had an easy time with Richard Sterne to win his eighth straight match, and next faces the last player to beat him in this event — Martin Kaymer, who defeated Rafael Cabrera Bello of Spain.

LPGA — Stacy Lewis shot a 3-under 69 to hold a three-stroke lead over Ariya Jutanugarn (66) after the second round of the LPGA Thailand in Chonburi.

Lewis had five birdies and two bogeys to follow up her 63 Thursday for a 12-under 132 total at the Siam Country Club Pattaya Old Course, replicating her 2012 form that made her the first American to win the LPGA Player of the Year award since Beth Daniel in 1994.

Beatriz Recari (68), So Yeon Ryu (68), and Catriona Matthew (69) were tied for third at 8 under, a shot ahead of Se Ri Pak (68) and Lizette Salas (69).

Former champion Ai Miyazato (71), Lydia Ko (71), Jessica Korda (67), and Karrie Webb (71) had a share of ninth place at 4 under.
