Both of Hong Kong's 4x100m medley relay teams made it to the final of the National Games on Monday, on the last day of the swimming competition.

The men's time of a little more than 3 minutes and 43 seconds was good for sixth overall.

George Chan, Adam Mak, Ralph Koo and Lau Ping-chi were racing in the heats that saw two faster teams, from Ningxia and Zhejiang, disqualified.

They're due to compete in the final at 8.18pm on Monday night.

Meanwhile, the women's team of Cindy Cheung, Eunis Man, Kassy Yeung and Li Sum-yiu clocked a little more than 4 minutes and seven seconds.

That's the seventh fastest time entering the final.

But before their races take place, all eyes will be on Hong Kong sensation Siobhan Haughey, who already has two gold medals at the Games.

She'll look to add to her haul in both the 50m freestyle and breaststroke finals in back-to-back races, starting from around 7.05pm.
