IRVING, Texas (AP) -- Lydia Ko had a triple bogey after losing a ball in a pine tree and dropped three more strokes on the next two holes Thursday to put her career-long LPGA Tour cuts streak in jeopardy in the North Texas Shootout.
Ko finished with a 4-over 75 at Las Colinas, leaving the top-ranked New Zealander nine strokes behind leaders Juli Inkster, Cristie Kerr and Sydnee Michaels.
Coming off a victory Sunday in California, the 18-year-old Ko had the triple bogey on the par-4 14th, followed with a double bogey on the par-4 15th and a bogey on the par-4 16th. She was tied for 117th in the 144-player field that will be cut to the top 70 and ties after the second round and to the top 50 and ties after the third. Ko has made the 36-hole cuts in all 50 of her LPGA Tour starts.
Ko said Wednesday that she will donate her earnings this week to the earthquake relief effort in Nepal.
The 54-year-old Inkster also shared the first-round lead last week in California and ended up tying for 15th. She won the last of her 31 tour titles in 2006.
Kerr won the Kia Classic in late March for her 17th tour victory.
Michaels is winless on the tour.
