Trio tied for the lead in Mexico

Ryu So-Yeon, Anna Nordqvist and Pornanong Phatlum are tied for the lead after the second round of the LPGA Lorena Ochoa Invitational.

South Korea’s Ryu and Sweden’s Nordqvist both carded five-under par rounds of 67 on Friday, while overnight leader Phatlum had to settle for a 69 as the trio ended Friday’s second round at the Guadalajara Country Club on nine-under.

The 18-year-old American Lexi Thompson was tied for four place, one shot behind the leaders, after carding a 64 – the lowest round of the day.

Joining the teenager on eight-under is world number one Inbee Park and another American Gerina Piller, who carded a 68 and a 65 respectively.

The 2011 US Women’s Open champion Ruy was level par over the front nine, but made five birdies on the back nine to move to the front of the leaderboard.

Her playing partner Nordqvist had a far more eventful round, opening with a birdie but then dropped a shot at the third. She then made birdies at seven, 11, 12, 15 and 18.

“It’s just a fun atmosphere,” Nordqvist said after her round.

“You just try to keep up and you know feed off of each other and give yourself a lot of chances for birdies.”

The 23-year-old Pornanong, who won the unofficial LPGA Brasil Cup last year and was runner-up this year at Mobile Bay, made back-to-back birdies at six and seven, but followed that with the only bogey of her round at eight.

She then made another birdie at nine and 16.

“Today, I’m very happy with my score, but the putting was not very good today. I just missed a few short putts,” Pornanong said.
