Yani Tseng missed a chance to tie the record she shares at 8 under for the best nine-hole score in LPGA Tour history. She also missed out on the outright lead in the RR Donnelley LPGA Founders Cup when her short birdie try slid left on the final hole.
The top-ranked Taiwanese star made about everything else on the back nine Thursday at Wildfire Golf Club, playing a seven-hole stretch in 7 under and finishing with a 7-under 65 for a share of the first-round lead with Hee Young Park.
"Yesterday, I was reading the player guide and I look at all the records and I see lowest nine holes was me. I was 8 under," Tseng said. "I didn't pay attention about that until after I missed the putt the last hole."
Tseng birdied the 11th, 13th and 14th holes, eagled the par-5 15th, and birdied the 16th and 17th. On the 18th, she hit a 7-iron from 168 yards to 4 feet, then pulled her birdie putt just wide.
"I tried too hard on the last hole," Tseng said. "I think it's harder at the end because you are trying, you're saying, `Oh, I have three, I have four.' And you want to go five, six, seven, and every hole is harder. You're just trying harder and harder."
Park closed with a bogey on the par-4 ninth for her 65.
"Most of the shots were perfect," the South Korean player said.
Jiyai Shin opened with a 66, and second-ranked Na Yeon Choi was another shot back along with Karen Stupples, Pernilla Lindberg and Hee Kyung Seo in the LPGA Tour's first U.S. event of the year after stops in Australia, Thailand and Singapore.
Tseng successfully defended her Honda LPGA Thailand title in February for her 13th LPGA Tour victory. She led the tour last season with seven victories -- including major victories in the LPGA Championship and Women's British Open -- and finished the year with 12 worldwide titles.
Playing in the late afternoon with the temperature in the low 80s in perfect conditions, Tseng holed a 9-foot putt on the 485-yard 15th after fading her 219-yard approach with a rescue club to the middle pin placement.
"It was a little fade, a little cut there," Tseng said. "It was just a little crowd, so I didn't know if my ball was close or not. But I had a good shot, and it was like 9 feet, and a pretty straight putt."
On the par-4 16th, her short iron shot to the elevated green spun back to 8 feet to set up a birdie. She then hit to 3 feet on the par-3 17th for her final birdie.
"I just hit it one shot at a time, because I don't even know what hole I am on," Tseng said. "I just really focus on one shot at a time, try to hit a good drive, get a good second shot and make good putt."
She played the first 10 holes in even par, countering a bogey on the fourth with a birdie on the par-5 fifth.
"I was missing a few putts," Tseng said. "But I kept telling myself, `Just be patient.'"
Park won the season-ending Titleholders last year for her first LPGA Tour victory. She birdied all four par-5 holes, and holed a 15-foot birdie putt on the par-4 eighth -- her 17th hole -- to get to 8 under.
"I played really good on the fairway," Park said. "I hit the fairway and then green. Lucky thing was most putts, birdie putts, were uphill. So, that's why I just hit it aggressive."
Shin birdied three of her final five holes in her bogey-free round.
"The weather was perfect this morning, no wind, and the greens were soft," Shin said. "I know this course is pretty tough. Desert course is always tough because the bounce, and the rough is pretty tough. I just more focus to the accuracy with my shot."
After winning eight LPGA Tour titles in a three-year stretch, Shin failed to win last season. In a bid to shake things up, she has a new blonde hairdo.
"A lot of Asian players play here. They're black or dark brown, so I wanted to make like fresh," the straight-hitting South Korean said,
Defending champion Karrie Webb was in a group at 68 that included Kraft Nabisco winner Stacy Lewis, U.S. Women's Open champion So Yeon Ryu, Cristie Kerr and Ai Miyazato. Lewis birdied the par-5 fifth -- her 14th -- to top the leaderboard at 6 under late in the morning session, but had a double-bogey 6 on No. 8.
Stupples had surgery last week to remove an ovarian cyst and polyps. She withdrew from the pro-am Wednesday and was worried about being able to play Thursday.
"I went through the warmup," the English player said. "Everything felt great on the warmup and I said, `Let's give it a go.' So, here we are."
She lost 21 pounds before the start of the season.
"It got to the point last year where I was over in Malaysia and really struggling playing in the hot weather and the temperatures," Stupples said. "We play so much overseas and a lot of high temperatures, and I really felt like the weight I was at was holding me back from achieving what I wanted to do. ... If you're not carrying an extra 20 pounds around, it has to make a huge difference."
