India’s HS Prannoy went down fighting in three games to China’s Lu Guang Zu in his second Group A match to bow out of the semi-final race at the BWF World Tour Finals here on Thursday.

The 30-year-old from Kerala, who had lost to the same opponent in his only meeting at the French Open this year, put up a brave effort but couldn’t go the distance, losing 21-23, 21-17, 19-21 in a gruelling 84-minute contest.
