Indian shuttler PV Sindhu crashed out of the Japan Open in Tokyo on Friday after losing in the quarter-finals on Friday.

Sindhu battled hard before going down to Akane Yamaguchi 18-21, 15-21.

Earlier, B Sai Praneeth continued with his good form as he advanced to the semi-finals after an easy win over Indonesia's Tommy Sugiarto.

Sai Praneeth recorded a straight game 21-12, 21-15 win over Sugiarto in the men's singles quarter-final match. He next faces top seeded Japanese Kento Momota for a place in the final.

Sai Praneeth hardly broke a sweat in his 36-minute win.

The unseeded Indian led almost all through the first set after 1-1 and the former World Championships bronze medallist Indonesian was playing a catch-up game.

The second game was a bit closer but Sai Praneeth led from the start to the end though not more than four points separated the two before the Indian reeled off three consecutive points from 18-15 to win the match.
