Juncheng Shang blunted Sumit Nagal's challenge at Australian Open in Melbourne to halt Indian star's impressive run at the first major of the season here on Thursday. Coming into the match after an inspiring win over a top-30 player, Nagal began in the same dominating fashion but the 18-year-old wild card entrant got better as the game progressed to walk out a winner with a 2-6 6-3 7-5 6-4 scoreline.
