BERNARD Tomic knows first-hand what Victor Estrella Burgos can do and that's why he will not be taking the man from the Dominican Republic lightly when they meet at the Australian Open today.
Tomic, who is seeded 27 at Melbourne Park, might be ranked 74 places above his opponent but after defeating him in a match that included three tiebreakers on his way to a second Bogota Open title three years ago, the Australian knows what to expect.
"He's a competitor and a fighter,” Tomic said.
"This match is going to be tough.”
Tomic was in good serving form as he sent down 12 aces in his straight-sets success over Brazilian Thomaz Bellucci in the first round and knows he must serve well if he is to beat the central American.
"I was serving at a high percentage,” he said.
"Once I do that, I'm feeling pretty well on court and playing good tennis and having fun.
"That's important for anyone, really, that's got a good serve, to serve well on their day and you get a lot of free points easy.
"Last year I was fourth on percentage.
"I think Rafa (Nadal) was one, (John) Isner was (two), Nick (Kyrgios) was three and I was four on percentage first serves.
"That's my game. If my first serve is working, then everything comes smoothly.”
A Tomic victory would set up a possible fourth-round clash with seventh seed Marin Cilic or resurgent Brit Dan Evans on Friday for a place in the fourth round.
Four other Australians are in action today.
Nick Kyrgios takes on Italian Andreas Seppi and is expected to advance, while teenage wildcard Alex De Minaur will find it tough against big-serving American Sam Querrey.
"Everybody here is a tough match. Obviously (he has a) great serve, great forehand,” said 17-year-old Alex De Minaur, who defeated Austrian Gerald Melzer in five sets in round one.
"(I'll) probably just try to get the return back and then we'll see what happens. Try and focus and play my game.”
Fellow 17-year-old Jaimee Fourlis will also find her next opponent, two-time grand slam champion Svetlana Kuznetsova, hard to beat, but she is keen to have a crack against the women's eight seed.
"I can go in with an open mind and just have a bit of fun with it,” she said after getting her maiden grand slam win on Monday against Anna Tatishvili 6-4 6-3.
"It's not every day a 17-year-old gets to play in the second round of a slam.”
Ashleigh Barty will fancy her chances against American Shelby Rogers, who upset fourth seed Simona Halep in round one.
If the Queenslander wins she could line up a third-round clash with Olympic champion Monica Puig.
