Zhang was rock-solid thereafter, parring the next nine holes before a two-putt birdie on 17 lifted her into red figures for the Championship.
A bogey at 18 represented a slightly disappointing finish, but Zhang still made the cut with ease and will now hope to further improve her position over the weekend.
Mizuki Hashimoto, the winner of the Women’s Amateur Asia-Pacific Championship, and Valery Plata, champion at the inaugural Women's Amateur Latin America presented by The R&A and ANNIKA Foundation, each finished on seven-over-par, with the latter shooting 72 on Friday to improve on her previous score by five.
They were narrowly ahead of Ingrid Lindblad, second in the World Amateur Golf Ranking® behind Zhang, who was eight-over for 36 holes after rounds of 74 and 76.
Caley McGinty deserves huge credit for bouncing back from Thursday’s 82 with an excellent 69. At nine-over, she finished on the same total as Anna Davis and one ahead of Savannah De Bock, while Women’s Amateur Champion Jess Baker shot 79 and 76 to be 13-over.
