The last time Sindhu was up against Chaliha, at the 83rd Yonex-Sunrise Senior National Championship in 2019, the youngster from Assam had produced a spirited performance.
On Friday, Chaliha took time to get into the groove and put up a good fight in the second game but couldn’t stop Sindhu from walking away with the match.
Sindhu came out all guns blazing in the opening game, jumping to a 11-5 lead at the interval and then reeling off the last 10 points to earn the bragging rights.
Chaliha gave a better account of herself in the second game as she tied 9-9 before Sindhu managed a slender one-point advantage at the break. Sindhu zoomed to 15-11 but Chaliha again clawed her way back to 15-15.
Thereafter, Sindhu switched gears and grabbed four match points. Chaliha saved two match points before Sindhu closed out the match.
