Very well played by Udomchoke. His flat groundstrokes and slice BH were causing JC all sorts of problems. Defensively, he was also superb with some incredible court coverage. Also, for such a short guy, his serve was very effective. All round a very good performance.
JC has got to go back to the drawing board and do some serious thinking. His attitude, after the 2nd set, was terrible. He only won the 3rd set because of Udomchoke's UEs. To make matters even more embarrassing, Danai was cramping in the 4th set but JCF he still couldn't take advantage.
