BERNARD Tomic admitted he could have gone the same way as Nick Kyrgios if he had allowed his match with Victor Estrella Burgos to go into a final set decider.
Kyrgios let slip a two-set lead to lose in round two to Italy's Andreas Seppi.
Tomic also went two sets ahead against his Dominican Republic opponent before scraping home 7-5 7-6 (7-4) 4-6 7-6 (7-5).
The 27th seed said he was relieved to have got through to round three, where he will face Britain's Daniel Evans who upset seventh seed Marin Cilic.
"I don't know how he lost that match, he was up two sets to love and it was a similar situation here,” Tomic said of Kyrgios.
"It almost happened to me, if we get to a fifth set who knows.”
Tomic is now Australia's best chance of getting through to week two.
He expected a tight clash against his mate from Central America, who he faced in Bogota on his way to the ATP title there three years ago.
"I was in control, up two-love and then everything changed which was a pity,” 24 -year-old Tomic said.
"He started going for more in the third and credit to him, his third and fourth sets were amazing.”
Tomic said he was happy with his form, particularly his serve.
"I was working on my serve basically the last two weeks, in the exhibitions, regardless of the scores where I won or lost, it didn't matter to me, I was just focusing on my serve and my percentage,” he said.
"I think I was fourth last year on percentage of first serves. That's the key to my tennis.
"When I'm doing that, I'm a different player. ”
