A week after eliminating Anthony Ginting, Leong Jun Hao dished out an even bigger upset after he sent Indonesia’s Jonatan Christie packing in front of his home crowd at the Indonesia Open on Wednesday.

Leong has surely delivered one of the upsets of this Super 1000 men's singles event after he defeated the third seed 21-13, 16-21, 21-12 to check into the second round.

This has to be one of the biggest career wins for the world number 32, who has upset one of the in-form men’s singles shuttlers on his home turf.

Leong turned in a fine attacking performance to take the lead against a jittery looking Christie who also contrived to send many shuttles wide.

The Malaysian could have closed out the match in straight games with a 15-11 lead in the second game, but Christie valiantly fought back to win that and force a decider.

Armed with the momentum, the world number three looked favourite to win the third game, but it was Leong who instead came out all guns blazing.

Picking the right moments to attack, the KL-born’s smashes was simply too powerful for Christie, while his net-play also left the Indonesian struggling to retrieve.

As a result, the deserved victory was secured after 62-minutes, as Leong left the court all smiles while carving a priceless moment of his career.

The 24-year-old will meet the champion of Chinese Taipei duo Chou Tien-chen or Lin Chun-yi.

Two other doubles pairs, Vivian Hoo-Lim Chiew Sien and Yap Roy King-Valeree Siow both crashed out after losing their matches.
