MELBOURNE, Australia - Milos Raonic advanced into the second week of the Australian Open for the third time in five years on Saturday. Fellow Canadian Vasek Pospisil did not.

Raonic was always in control as he won comfortably against Germany's Benjamin Becker 6-4, 6-3, 6-3 while Pospisil was beaten 6-2, 6-4, 6-4 by Spaniard Guillermo Garcia Lopez.

Becker, who eliminated Australian Lleyton Hewitt in the previous round, was no match for 22 aces off the racquet of the eighth seed from Thornhill, Ont.

It took the winner four match points to see off Becker with a break in the last game. Becker saved the first three Raonic winning chances before the Canadian went through from Becker's double-fault.

Raonic took victory with 46 winners, 19 unforced errors while breaking on five of 14 opportunities.

Raonic will next face 12th-seeded Feliciano Lopez of Spain, who beat Poland's Jerzy Janowicz 7-6 (8-6), 6-4, 7-6 (7-3).

"I'm happy with how I'm playing," said Raonic, who played and won on the third showcase court, the Hisense arena. "I can't complain, everything has been working for me on this court and the results have been good.

"My game feels great and I'm having a lot of fun. I look forward to going on."

Vancouver's Pospisil had been bidding to join Raonic by reaching the fourth round of a grand slam for the first time.

But the fitness factor came into play for the No. 60, who had suffered in his previous win on Thursday and withdrew after just nine minutes of doubles on Friday.

The Canadian came to the court depleted, committing 40 unforced errors and breaking only one of six times.

Pospisil dropped the first two sets but staged a minor rally in the third set, firing off two love games for a 2-1 lead before being overhauled by his Spanish opponent.

The Canadian saved a match point before going down to the loss as Garcia Lopez backhand sailed a winner past him down the line.

Raonic's victory in 101 minutes improved his record over the 41st-ranked Becker to 3-1. Raonic, who played the Wimbledon semifinals last summer, won his 13th career match in Melbourne against four losses.

Raonic was never threatened by his journeyman opponent, winning each of the first two sets in 30 minutes.

Raonic claimed the opener with a break in the final game with a forehand winner to the corner past Becker. The second set also featured only one break, with Raonic converting for a 4-2 lead.

Two games later, Raonic set up two set points with an ace only to double-fault the first chance away. But his 17th ace solved the problem on the second opportunity as he earned a two-sets-to-love lead.

In the third set, Raonic broke in the fifth game and climbed to 5-3 before closing it out.
