One day after failing to make a bogey, Jeeno Thitikul made only one birdie at the AIG Women's Open. The overnight leader after Round 1 of the season's final major shot 2-over 73 Friday to fall to 5 under, two back of leader Haeran Ryu. She dropped shots at the third, 11 th and 14 th holes to drop off the pace, but not out of contention. Hull holed a bunker shot for birdie at the par-4 17th on her way to an even-par 71. Playing alongside Thitikul, Yamashita made a quadruple bogey at the last when her greenside bunker shot failed to clear the face and rolled back into her footprint.
