Kim Young was unable to take advantage of a booming drive at the ninth, hitting her second shot over the green and behind a pair of signs next to the 15th tee.
She took a drop, then chipped 5m past the hole.
She missed the putt coming back to fall into a tie with Creamer at 18 under.
Bader wasn't out of it, either. After making bogey on two of her first three holes, she rallied with two birdies before the turn and trailed by one.
A birdie at No. 12 moved her to 18 under.
Kim Mi-hyun, playing in the threesome ahead, started the day a shot behind and moved into contention at the turn.
She birdied both par 5s on the front side and took a brief one-shot lead with birdies at Nos. 10 and 12 before bogeying No. 14.
