Leona Maguire kept herself within one shot of the lead at the LPGA Mediheal Championship after a tough second day in California.
The world number 92, who led by a stroke after a first round of seven-under 65, struggled at the start of the second round in Daly City with bogeys on the first three holes before she picked up some momentum as she birdied the seventh and ninth.
The Cavan golfer then mixed in bogeys on the 11th and 16th with birdies on the 12th and 15th to card a one-over 73, finishing in a share of second with American Lauren Kim, whose compatriot Danielle Kang led the field at seven-under after a 66.
"I got off to a rough start and bogeyed my first three holes," said Maguire after her round.
"But I'm really proud of how I sort of hung in there and battled back and holed some really nice putts and got some really nice up and downs and keep the round going. Kept myself in the tournament."
Min Lee is one shot behind Maguire in fourth, while the quartet of Alison Lee, Jane Park, Jennifer Coleman and Matilda Castren round out the tie for fifth on four under.
Antrim's Stephanie Meadow missed the cut by seven shots after carding a 75 that left her on 11 over for the tournament.
