HILTON HEAD ISLAND, S.C. (AP) - Jordan Spieth had a post-Masters letdown Thursday, shooting a 3-over 74 at the RBC Heritage to end his run of 16 straight rounds under par.
Spieth vowed his whirlwind, two-day celebration tour of New York after winning the green jacket Sunday wouldn't affect his focus. But it was apparent early on at Harbour Town that Spieth was not at his best.
The 21-year-old Texan was eight shots behind leaders Graeme McDowell and Matt Every, who were at 5-under 66. Spieth will need significant improvement Friday to make his eighth consecutive cut.
He got into Sea Pines Resort late Tuesday night after some 25 appearances and interviews in New York, including an appearance with David Letterman and seeing the view atop the Empire State Building. He acknowledged his preparation this week had suffered, but vowed not to have the major hangover several champions have when playing so soon after such success.
Spieth entered the week with four straight top-two finishes, also winning the Valspar Championship in a playoff at Innisbrock, finishing second in the Texas Open and losing in a playoff in the Houston Open.
Sangmoon Bae was third at 67, and defending champion Matt Kuchar topped the group at 68.
LOTTE CHAMPIONSHIP
KAPOLEI, Hawaii (AP) - Sei Young Kim shot her second straight 5-under 67 for a share of the second-round lead with fellow South Korean player I.K. Kim in the breezy Lotte Championship.
Sei Young Kim, the Pure Silk Bahamas LPGA Classic winner in February in her second start as an LPGA Tour member, had seven birdies and two bogeys at Ko Olina.
I.K. Kim fell back with bogey at the ninth, but charged into a share of the lead with birdies at Nos. 14 and 15. The three-time LPGA Tour champion had a 69.
South Korean players held six of the top seven spots. Third-ranked Inbee Park (70) was three shots back, and American Paula Creamer bogeyed the final hole for a 69 to match Chella Choi (68), Mirim Lee (69) and Jenny Shin (70) at 6 under.
Defending champion Michelle Wie was tied for eighth at 5 under after a 69 in her home event. She holed out for eagle from 117 yards out on the par-4 15th hole.
SHENZHEN INTERNATIONAL
SHENZHEN, China (AP) - Huang Wenyi, a former laborer from China who didn't start playing golf until he was 22, shot a 6-under 66 to take a one-stroke lead in the Shenzhen International.
The 34-year-old Huang had eight birdies and two bogeys at Genzon Golf Club. American Peter Uihlein was tied for second with Chile's Felipe Aguilar, Thailand's Kiradech Aphibarnrat and South Korea's Byeong Hun An. Two-time Masters champion Bubba Watson opened with a 70.
