Like the rest of the field, Australian Karis Davidson is playing catch-up after Ina Yoon established a commanding five-shot halfway lead at the Women's PGA Championship in Minnesota.
Yoon's second-round 69 vaulted the South Korean to 12 under for the $13 million ($A18.2 million) championship, as Davidson lost touch with a two-over 74 on Friday (Saturday AEST).
"This is actually my first time being in the lead going into the weekend. It's actually really nice experience for me," Yoon said.
