Defending champion P V Sindhu marched into the final of the women's singles at the US $120,000 Macau Open Grand Prix Gold on Saturday.

World No 11 Sindhu displayed a dominating game as she beat Busanan Ongbumrungpan of Thailand 21-14, 21- 15 in a 42-minute match, at the Tap Seac Multisport Pavilion.

The two-time World Championship bronze-medallist, Sindhu, held an all-win 4-0 record against Busanan Ongbumrungpan of Thailand before coming into the match and the Indian kept her record intact by registering her fifth win.

In the quarter-finals, Sindhu went through some anxious moments before beating fifth seed Han Li of China 21-17, 19-21, 21-16 in a little over an hour.

But young shuttler H S Prannoy lost despite a valiant fight in the men's singles semifinals.

Prannoy waged a fierce battle but still failed to breach the defence of Wing Ki Wong of Hong Kong, who prevailed 21-16, 16-21, 21-12 in the match that lasted an hour.
