It's been nine years since Christina Kim last won on the LPGA Tour, but after a sizzling 65 she is in position to end that drought in Mexico. Here's how things look after the first round of the Lorena Ochoa Invitational, where Kim leads by a shot:
Leaderboard: Christina Kim (-7), Azahara Munoz (-6), Lydia Ko (-4), Pornanong Phatlum (-3), Gerina Piller (-3), Lizette Salas (-3)
What it means: Only 36 players are teeing it up this week in Mexico City, but there were still plenty of low scores to go around - none lower than Kim's. She sits in front by a shot, but newly-named Rookie of the Year Ko lurks just three off the pace. Paula Creamer, Inbee Park and Lexi Thompson are among those at 2 under.
Round of the day: Kim scorched the par 5s, playing them in 4 under after eagles on Nos. 2 and 17. She added a trio of birdies and made it around without a bogey, hitting 16 of 18 greens in regulation while taking just 27 putts.
Best of the rest: Munoz was a part of the winning team at the inaugural International Crown this summer, and she is in contention for her second individual title on the LPGA after a 6-under 66. The Spaniard cancelled a pair of bogeys with an eagle on the par-5 17th, then added six birdies including three in a five-hole stretch from Nos. 12-16. She found only five fairways, but like Kim reached 16 of 18 greens in regulation.
Biggest disappointment: Stacy Lewis is in a tight race for Player of the Year honors, and she did herself no favors with a 4-over 76. Lewis failed to make a single birdie and stumbled to bogey-double bogey on Nos. 8 and 9. As a result, she's already 11 shots off the pace.
Main storyline heading into Friday: Kim has shown signs of a resurgence this season, but it remains to be seen how she can play from the front of the pack. After an opener that put her well in front of nearly the entire field, she'll look to remain in position for her first top-10 finish since a runner-up at the ShopRite LPGA Classic in May.
