Canada's Felix Auger-Aliassime lost 7-6 (4), 6-1 to Japan's Kei Nishikori in the first round of the ABN AMRO World Tennis Tournament on Monday.

The seventh-seeded Auger-Aliassime, from Montreal, got just 54 per cent of his first serves in, well below Nishikori's 74 per-cent clip.

Nishikori, ranked 45th in the world, hasn't dropped a set in two career matches against Auger-Aliassime.

The 20-year-old Canadian was playing for the first time since blowing a two-set lead in a fourth-round loss to Aslan Karatsev at the Australian Open.

Nishikori will play the winner of a match between Australians John Millman and Alex de Minaur in the second round of the ATP Tour 500 event.

Kerri Einarson won a second straight Canadian women's curling championship with a 9-7 win over Ontario's Rachel Homan on Sunday.

Einarson, third Val Sweeting, second Shannon Birchard and lead Briane Meilleur from Manitoba's Gimli Curling Club defeated Homan in the Scotties Tournament of Hearts final for the second time in as many years.

Einarson's team was the first to repeat since Homan in 2013 and 2014.

Einarson had to make a draw with her final shot in an extra end to claim her first championship in Moose Jaw.

The skip didn't have to throw her final stone Sunday in Calgary.

Einarson lay two counters in the rings when Homan was too deep on an attempted freeze.
