GUADALAJARA, Mexico (AP) -- Sweden's Anna Nordqvist and South Korea's So Yeon Ryu each birdied the final hole for a share of the second-round lead with Thailand's Pornanong Phatlum on Friday in the Lorena Ochoa Invitational
Nordqvist and Ryu shot 5-under 67 to match Phatlum at 9-under 135 at Guadalajara Country Club.
Nordqvist and Ryu played in the same group.
''I'm always really happy to play with Anna,'' Ryu said. ''We have so much fun always, so I love it. We pretty much played so well, especially on the back-nine. We hit a really great shot and she made every birdie putt. I was really excited to see her, to see how she is playing.''
Nordqvist is winless on the tour since the 2009 LPGA Tour Championship.
''We're only halfway through and, obviously, the best golfers in the world are here so you can't really think about winning or leading the tournament right know,'' Nordqvist said. ''We have two more days, so you have to try to play your game and put low scores out there.''
Phatlum, the first-round leader in the 36-player event, had a 69.
''I'm very happy with my score, but the putting not very good,'' Phatlum said. ''I just missed a few short putts.''
South Korea's Inbee Park was a stroke back along with Americans Lexi Thompson and Gerina Piller. Thompson had a 64 for the best round the first two days. Piller shot 65, and Park had a 68.
The 18-year-old Thompson won the LPGA Malaysia last month for her second tour title.
''I just went into today playing fearless and just committed to my lines,'' Thompson said. ''I dropped a few more putts today, and that always helps.''
The top-ranked Park swept the first three major championships of the season and has three other LPGA Tour wins this season. She's winless in eight starts since the U.S. Women's Open in late June.
Second-ranked Suzann Pettersen and No. 3 Stacy Lewis were tied for ninth at 6 under.
Pettersen had a 68. The Norwegian player is coming off a successful title defense in the LPGA Taiwan, her third victory in her last five starts and fourth of the season.
Lewis shot a 66.
Michelle Wie had a 73 to drop into a tie for 20th at 2 under. She won the 2009 tournament for the first of her two LPGA Tour victories.
Defending champion Cristie Kerr was 27th at 2 over, following a 77 with a 67.
Tournament host Lorena Ochoa won 27 LPGA Tour titles before retiring in 2010.
''It's been great. I love Mexico,'' Piller said. ''Most people don't know this, but my maiden name is Mendoza. I don't speak much Spanish, but I love the food, love the people and it's just a great tournament. I never got to play with Lorena, but she's been a huge inspiration.''
