Malaysia kicked off their 2018 Asian Champions Trophy campaign with a winning start by edging Japan 3-0 in their opening match at the Sultan Qaboos Sports Complex in Muscat, Oman, on Thursday.

National forward Faizal Saari put Malaysia in front via a penalty corner in the third minute before Tengku Ahmad Tajuddin Tengku Abdul Jalil increased the lead via another penalty corner.

Faizal bagged his second goal of the match after converting a penalty stroke in the 51st minute.

National head coach Roelant Oltmans said he was delighted with the "perfect start" but noted that there was room for improvement in several aspects.

"No weakness, but there is always room for improvement, especially in possession.

"Most importantly for us is to improve ourselves. If we do so, we have a good chance to finish off with six points after two matches," he said.

Malaysia will meet hosts Oman in the second match on Saturday.
