Park sits two-strokes ahead of So Yeon Ryu, Ally McDonald and Mel Reid.Local favorite Stacy Lewis and 56-year-old Juli Inkster were at 66 along with Felicity Johnson, Moriya Jutanugarn, and Katherine Kirk. But yeah, I mean, a hole-in-one, I hit a good shot into there. “It just pitched a little longer than we thought”.Speaking after her record-breaking feat, Ryu said: “When I hit a really low score, one thing I learn is that I never look at the big picture”.A day after opening with a 65 in gusty afternoon conditions, Ryu preyed on the Pinnacle Country Club course on a calm Saturday morning.Reid’s round was highlighted at the 11th where she made a hole-in-one that pushed her to 8 under.Former world No. 1 Ai Miyazato shot a 72 in her first round in the USA after announcing last month that she plans to retire at the end of the season. “So I try not to just not think about the draw too much”. “Even past year, she played a few LPGA tournaments as a non-member, but she would finish top-five, top-10″.She also has top-10 finishes in the past two El Dorado Shootouts on the Symetra Tour, 10th in 2016 and 2nd as an amateur in 2015.Ryu, the world’s third-ranked player, led the afternoon wave with four birdies on the back nine to get to 65. “Also, I played with Nick Price, which it was really a pleasure to play with him”. “It feels great to be back and hopefully I can have a really great bogey-free round again”. Instead, McDonald elected to play a full schedule on the Symetra Tour where finished second on the money list, earning a record $110,359, second only to Madelene Sagstrom who won the money title. “I’ve played great in the past, and I’m trying to gain some confidence before going [to the KPMG Women’s PGA next week]”.
