Even by his own exacting standards, Roger Federer served stupendously well against Alexander Dolgopolov in their second-round clash at the Australian Open on Wednesday.

The Swiss maestro played some pretty mean defensive tennis as well.

The end result a 6-3 7-5 6-1 victory after Federer crashed 25 aces past the Ukrainian while not having to face a single break point.

Next up is a third-round clash with the talented Grigor Dimitrov, a man often dubbed mini-Fed.

It’s a moniker that doesn’t sit comfortably with the Bulgarian, who saw the unexpectedly stiff challenge of world No.210 Marco Trungelliti from Argentina to win 6-3 4-6 6-2 7-5.

It’s been three-and-a-half years since the 34-year-old Federer won the most recent of his record 17 grand slam titles at Wimbledon.

The key moment came in the 11th game of the second set when Dolgopolov made a hash of an ill-advised drop shot, opening the door for Federer to break for 6-5.

“The conditions are extremely quick so you’re not going to find that much rhythm,” said Federer, who has won four Australian Open crowns.

“I thought I served great.

“As the match went on I felt better and better, but the second set was clearly crucial.”

A host of other leading men’s seeds joined Federer in marching into the round of 32 on Wednesday, including world No.1 Novak Djokovic.

Djokovic defeated Frenchman Quentin Halys in straight sets to continue his assault on a sixth title at Melbourne Park.

For two sets, Djokovic was in relentless form against the teenager, winning 6-1 6-2 7-6 (7-3) in 100 minutes on Rod Laver Arena.

No.6 Tomas Berdych was untroubled in ousting Bosnian qualifier Mirza Basic 6-4 6-0 6-3.

The Czech has reached the semis at Melbourne Park in each of the past two years, but he’ll need to beat Australian firebrand Nick Kyrgios to get there this year.

Kyrgios was largely untroubled in defeating Pablo Cuevas 6-4 7-5 7-6 (7-2).

Kei Nishikori also eased into the round of 32 with a straight-sets win over American Austin Krajicek.

The No.7 seed eclipsed his long-time friend and training partner 6-3 7-6 (7-5) 6-3.

Nishikori’s best result at Melbourne Park is the quarter-finals, which he reached in 2012 and 2015.

Popular Frenchman Jo-Wilfried Tsonga dispatched Melburnian teenager Omar Jasika 7-5 6-1 6-4 and will play countryman Pierre-Hugues Herbert on Friday.

Belgian 15th seed David Goffin is also through to the third round but not before suffering the indignity of a bagel in the second set against Bosnian Damir Dzumhur.

But Goffin recovered quickly, going on to win 6-4 0-6 6-4 6-2.

His third-round opponent will be Austrian 19th seed Dominic Thiem, who trounced Spaniard Nicolas Almagro 6-3 6-1 6-3.

No.12 seed Marin Cilic from Croatia downed Spaniard Albert Ramos 6-4 6-3 7-6 (7-4).
