After losing to Indonesia a day before, the win came as a morale boost ahead of the tough tie against South Korea on the last day. It was a stroll in the park for the Indians as they drubbed Mongolia. For the first time, they played on Court No.1, which is quicker and suits the Indians better than the slow, low bouncing centre court. Zeel Desai, playing his first match in the tournament, defeated Anu-Vjin Gantor 6-0, 6-0. Sahaja Yamalapalli also breezed past Jargal Altansarnai with the same scoreline. In doubles, Rutuja Bhosale combined with Vaishnavi Adkar, with Ankita Raina given a breather, and they hardly faced any resistance against Khongurzul Aldarkhishig and Jargal Altansarnai, winning 6-1, 6-0. Mongolia was the weakest team in the tournament, and India took full advantage. Though India's chances of qualifying for the playoffs are slim, the last tie against South Korea on Friday will be crucial, provided other results go their way. On Friday, the Indian camp kept an eye on the match between Indonesia and South Korea, with Indonesia winning 2-1.
