Men's third round winners on Saturday saw Federer, Rafael Nadal, Andy Murray, Jo-Wilfried Tsonga, Dimitrov, Kei Nishikori, Roberto Bautista Agut and Stephane Robert all recording victories to advance to the Round of 16 at the Australian Open.
The first men's third round match up on Rod Laver Arena saw four-time Australian Open winner Roger Federer in action against world No. 79 Russian Teymuraz Gabashvili.
And the 32-year-old former long-time world No. 1 cruised to the straight-sets victory with Federer still not having dropped a set in this year's Australian Open.
Federer won 6-2, 6-2, 6-3 to advance to the fourth round where he will certainly face a Frenchman, either Jo-Wilfried Tsonga or Gilles Simon.
The afternoon session on Margaret Court Arena on Saturday finished with a battle of the rising stars when Bulgaria's Grigor Dimitrov took on Canada's Milos Raonic.
A marathon contest loomed when the match was tied at a set apiece but then the 22nd-seeded 22-year-old Dimitrov took control.
He managed to break Raonic's impressive serve in the third set and then won the fourth 12 points to 10 in the tie-break after previously blowing five match points.
Dimitrov recorded the 6-3, 3-6, 6-4, 7-6 (10) victory as he advanced to a Grand Slam fourth round for the first time in his career.
French 27th-seed Benoit Paire might have outlasted Australian teenager Nick Kyrgios in the second round to win in five sets, but he was no match for world No. 62 Spaniard Roberto Bautista Agut in the third round on Saturday on Court 2.
Bautista Agut backed up his stunning second round upset of world No. 5 Juan Martin Del Potro by beating another seed to advance to the Round of 16 with the 6-2, 6-1, 6-4 thumping of Paire.
The reward for Bautista Agut is a fourth round clash with Murray.
Frenchman Stephane Robert and the Slovak Republic's Martin Klizan both lost in qualifying at the Australian Open, but were handed spots in the main draw due to two late withdrawals and remarkably they meet one another on Saturday with a fourth round berth up for grabs.
The French world No. 119 proved too good in the finish for Klizan winning 6-0, 7-6 (2), 6-4 and he will now face Bulgarian Dimitrov in the fourth round as both look to advance to a Grand Slam quarter-final for the first time.
Play on Margaret Court Arena finished on Saturday with Japanese 16th-seed Nishikori cruising into the Round of 16 beating American Donald Young.
Nishikori's 7-5, 6-1, 6-0 means that there are no American men left in the draw at the Australian Open and the Japan 16th-seed will now take on world No. 1 Nadal in the fourth round.
The afternoon session on Hisense Arena then finished with reigning Wimbledon champion and three-time Australian Open runner-up Murray taking on veteran Spanish 26th-seed Feliciano Lopez.
Despite a tight first set where neither player gave an inch, Murray prevailed in the tie-break and despite a nagging sore back, cruised through the next two sets to record the 7-6 (2), 6-4, 6-2 win in what is his eighth straight victory over Lopez.
The night then concluded on Hisense Arena with what loomed to be an enthralling French battle between Tsonga and Gilles Simon.
However, Simon came into the clash with two gruelling five-set matches over the first two rounds and that clearly took a toll on him with the 10th-seeded Tsonga taking full advantage recording the comfortable 7-6 (5), 6-4, 6-2 win.
Tsonga will now take on Federer in perhaps the most eagerly-anticipated fourth round match-up.
The night at Melbourne Park then finished with world No. 1 Nadal doing battle with 25th-seeded flamboyant Frenchman Gael Monfils.
Despite Monfils possessing plenty of natural talent and flair, and being in good form, Nadal was in no mood to mess around and crushed the Frenchman in straight-sets 6-1, 6-2, 6-3.
Monfils was right off his game against the relentless power of Nadal's ground strokes with the Frenchman finishing the three sets with a monstrous 57 unforced errors as he failed to break the Spaniards serve once and had his broken six times throughout the match.
