In-form Prajnesh Gunneswaran inched closer to his maiden Grand Slam appearance with another straight-set win but Ankita Raina and Ramkumar Ramanathan were ousted from the Australian Open Qualifiers after suffering narrow defeats, here on Thursday.
Prajnesh, seeded sixth, got the better of Spain's Enrique Lopez Perez 6-3, 6-3 in the men's singles second round.
"I played a better match than yesterday and remained solid throughout. I did the right things, attacked when I got chances. Looking forward to the final round tomorrow," he added.
The world number 112 will next take on Japan's Yosuke Watanaki, ranked 192 in the world.
If Prajnesh wins Friday's match, it will be his first main draw competition at a Grand Slam. Injured Yuki Bhambri had played in all four Grand Slam main draws in 2018.
Placed 132 in the world rankings, Ramkumar played a very close match before losing 7-5 5-7 6-7(6) to Germany's Rudolf Molleker, ranked 207.
In the women's singles, Asian Games Bronze medallist Ankita also had a one-set advantage but went down 6-4 2-6 4-6 to Spain's 29th seed Paula Badosa Gibert, world number 142.
Meanwhile in the practice match, Novak Djokovic exposed Andy Murray's frailties in a practice match with the Scot calling it a day while losing 6-1, 4-1.
