Canada and the United States made it two wins from two in their respective groups on the second day of the International Swimming Federation Women's Water Polo World League Super Final at the Athens Olympic Aquatic Centre in Greece.

Leaders in Group A, Canada defeated Japan 16-10 to give themselves a good seeding for the quarter-finals.

Captain Monika Eggens scored three goals, helping her side stay in front after a strong second quarter gave them a commanding lead.

Emma Wright, Elyse Lemay-Lavoie, Hayley McKelvey and Kyra Christmas all scored two goals each to help Canada win by six.

Japan's star player was Yumi Arima who scored half of the team's goals, while Kako Kawaguchi added another four.

America, the defending champions, decimated Kazakhstan in Group B, laying down a challenge to the rest of the competition by emerging with a 20-2 win.

Stefania Haralabidis scored five, while yesterday's player of the match, Madeline Musselman, added three too.

Every outfield player except captain Margaret Steffens managed to get on the scoresheet during the rout.

Spain also ended the second day with two wins following a 14-8 victory over hosts Greece.

Bea Ortiz and Maica Garcia Godoy scored four and three goals each respectively to held their side to a win.

The hosts always looked on the back foot, chasing the game throughout after Ortiz put the side in front, with Spain later pulling the lead out to six points.

Russia managed to outscore Hungary in the final quarter to snatch victory in a back-and-forth affair, with the score finishing 14-13.

After the first quarter, the teams were level at 2-2 before Hungary took a two-goal lead at half time.

Elvina Karimova scored two to help Russia equalise at 11-11 at the end of the third quarter.

Goals from Maria Bersneva, Anna Timofeeva and Nadezhda Glyzina in the fourth quarter gave Russia three goals to Hungary's two from Greta Gurisatti and Rita Keszthelyi.
