China's Peng Shuai shattered 40-year-old Kimiko Date Krumm's dream of a second Asian Games title on Sunday to keep her triple gold bid on course. Peng clinched a 7-6 (8/6), 3-6, 6-2 win over the veteran Japanese, who won her first singles gold at the Hiroshima Asiad in 1994, and now faces Uzbekistan's Akgul Amanmuradova, who put out Indian golden girl Sania Mirza.
Peng, 16 years Date Krumm's junior, made the most of her opponent's inconsistency where an impressive 59 winners were cancelled out by 73 unforced errors and a morale-sapping six double faults.
World number 72 Peng has already helped China to team gold in Guangzhou and is also in the women's double semi-finals with Yan Zi. Mirza needed six set points to wrap up the opener after more than an hour on court against the big-hitting Amanmuradova who she had defeated in all three of their previous meetings.
But the Indian's game unravelled in the second set and the world 69 levelled the tie. As the clock ticked towards the three-hour mark, Amanmuradova's greater stamina paid dividends as she took victory on the first of three match points for a 6-7 (7/9), 6-3, 6-4 win.
Defending men's champion Danai Udomchoke was knocked out in the quarter-finals, losing to Japan's Tatsuma Ito 6-4, 6-1.
Top seed Denis Istomin of Uzbekistan reached the semi-finals after a 6-2, 4-6, 7-5 win over Karan Rastogi with the vanquished Indian praising his opponent's sportsmanship.
