The second seeded Indian won with a 5-7 6-2 7-5 scoreline in the final against her formidable rival, who happened to be her doubles partner in the event.
It was double delight for the 16-year-old Pranjala as she had won the doubles trophy yesterday.
Coached by former Davis Cup player Ilyas Ghouse, Pranjala trains at GVK Tennis Academy in Hyderabad.
"This competition is next to junior Grand Slams. The competition was intense. My opponent in the final is higher-ranked player and I had lost to her in the second round of ITF Grade I event in January. I am glad I could beat her this time," the Class XII student said.
