Bengaluru-based veteran Magimairajan brushed aside compatriot Meenal Thakur 3-1 for her fourth win while 22-year old Kamani from Mumbai chalked up her third win in as many matches by blanking Iran's Akram Mohammadi Amini 3-0 in Group D.
With top four players from each of the six Groups to qualify for the knock-out stage, both Magimairajan and Kamani were assured of their slots in the round of 24.
Meanwhile, one of the most talented Indian cueists Manan Chandra warmed up nicely for the difficult matches ahead by posting a fluent 4-0 win over New Zealand veteran Paul Bason for his third consecutive success in his group.
"I did play a few careless shots today, but otherwise, I am happy for my third win. I decided to play an open game and went for the breaks. I now have some tough matches ahead in the group and I hope to do well," said Chandra whose best break against Bason was an 82 in the third frame.
