Suzann Pettersen missed multiple starts earlier this season because of a bad back, but she had no such issues Thursday in the Lone Star state. Here's how things look after the first round of the North Texas LPGA Shootout, where Pettersen leads by one:
What it means: The leaderboard remains crowded in Dallas, with 19 players within three shots of the lead. Pettersen leads after a bogey-free effort, though, and after ceding the No. 2 spot in the Rolex Rankings to Lydia Ko last week, she appears eager to respond to Ko's victory with a win of her own.
Round of the day: In her second start back from the disabled list, Pettersen began with three birdies across the first eight holes, then capped her afternoon with birdies on Nos. 16 and 18. The Norwegian hit 17 of 18 greens in regulation and needed just 30 putts at Las Colinas Country Club.
Best of the rest: Wie continued her recent stretch of strong play with an opening 68. A winner last month in her native Hawaii, Wie tallied four birdies in addition to an eagle at the par-5 10th. Though she hit only six fairways, she reached 15 of 18 greens in regulation and is in line for her fourth straight top-10 finish.
Biggest disappointment: While many big names broke par Thursday, Inbee Park remained in idle after an even-par 71. Park made four birdies but also carded two bogeys and a double bogey on the par-4 15th. She reached 14 greens in regulation but still trails Pettersen by five shots.
Main storyline heading into Friday: Pettersen emerged from a logjam late in the afternoon, and she'll be the player to watch in the second round. There are plenty of top players among the chase pack, though, including Wie, Kerr and Lexi Thompson, who shot a 1-under 71 in her first start since winning her maiden major title at the Kraft Nabisco Championship.
