Schenk, however, put up a tough fight in the second game which witnessed long rallies between the two as they did not let any opportunity to score a point go by.
Saina had an edge of 7-6 by the first break and she succeeded in taking it to 14-8 by the second interval. Schenk, however, staged a remarkable comeback and leveled the score at 18-18, before taking the game at 21-19.
