The Indian pair had dropped to world No 27 after skipping a host of tournaments this year due to injury, but showed signs of their old form today as they swept aside the Malaysians 21-17, 21-15 in just 38 minutes in their quarter-final match.

The Indians have now beaten Sze Fei-Izzuddin four times in their seven encounters so far.

The Malaysian pair were also knocked out of the Malaysia Masters in the quarter-finals last week.

Malaysia suffered another blow in the quarter-finals as men’s singles shuttler Leong Jun Hao saw his Singapore Open run come to an end at the hands of reigning world champion Kunlavut Vitidsarn from Thailand.

The world No 25 shuttler tried very hard to match his Thai opponent but Kunlavut proved to be too strong, winning 21-13, 21-11 in 47 minutes.

Both players have met twice so far with the Thai winning on both occasions.

Despite the loss, Jun Hao’s performance in this competition was a marked contrast from being knocked out in the first round of his last five consecutive tournaments.

After receiving a first-round walkover, Jun Hao recorded a major upset in the last 16 yesterday when he defeated Indonesia’s Jonatan Christie, who is world No 5, in straight games.
