The 29-year-old Yuki who got a direct entry into the main draw recorded a 6-7 (10), 6-2, 7-5 win in his opener.

Earlier France’s Quentin Halys sent World No. 82 Ricardas Berankis of Lithuania packing with a stunning 6-1, 6-2 win.

In the other round-of-32 match, former World No. 39 Moldovan Radu Albot faced a tough challenge from Federico Gaio of Italy in the second set but managed to sail through with a 6-2, 7-6 (7-3) victory in the end.

Back to Yuki's match, after losing the hard-fought first set, the former junior world number one, started the second with 2-0 lead and looked in good touch. He didn’t let the momentum shift away before bagging the set easily and levelling the scores.

In the decider, the Delhi-born player, who made a comeback into the international circuit recently after a two-year break due to injury, converted a break point to take the scores at 3-3 and then added one more set point to keep himself ahead in the game.

Though the 29-year-old Slovakian tried his best to make a comeback into the contest, Bhambri held his nerves and clinched the decider to advance into the second round.

"Letting the first game slip was a bit yo yo. Sat down, got back but because it is so close and felt so comfortable that gave me confidence to keep attacking which helped me in the second set in the end," the Indian said after the match.

The World No. 141 Halys of France looked quite confident against the higher-ranked opponent as he hardly gave any opportunity to Berankis.

Meanwhile, top-seeded Australian pair of Like Saville and John-Patrick Smith defeated Stefano Travaglia and Bernabe Zapata Miralles 6-1, 6-4.

In the other doubles opening round match, French duo of Sadio Doumbia and Fabien Reboul outclassed the third-seeded pair of Szymon Walkow and Jan Zielinski 6-3, 7-6 (7-5) to move into the Last-8 stage.

In the singles qualifying matches played on Monday, Czech Republic’s Vita Kopriva stunned top-seed Turkish player Altug Celikbilek with a hard-fought 6-7 (7-4), 6-3, 7-5 win and made his way into the main draw.

Swedish player Elias Ymer also secured an entry into the main draw with an easy 6-4, 6-4 win over Australian Marc Polmans.

British Jay Clarke and Gian Marco Moroni of Australia were the other two players, who emerged victorious in the final qualifying round and entered the main draw.
