Milos Raonic returns a shot to Andy Murray during their match at the U.S. Open
Still seeking his first Grand Slam title, Olympic champion Andy Murray reached the quarterfinals at an eighth consecutive major tournament by beating 15th-seeded Milos Raonic 6-4, 6-4, 6-2 Monday night.
The third-seeded Murray converted 4 of 12 break points and never faced one, reports The Associated Press.
Murray, the 2008 U.S. Open runner-up, and his coach, Ivan Lendl, are the only men to lose their first four major finals.
Next for Murray is a match against No. 12 Marin Cilic. Murray leads their head-to-head series 6-1, but his only loss to Cilic came at Flushing Meadows in the fourth round in 2009.
Raonic was trying to become the first Canadian man in a Grand Slam quarterfinal in the Open era, which began in 1968.
In another game, Serena and Venus Williams exited in the third round of doubles at the U.S. Open on Monday night, losing 6-1, 6-4 to the fourth-seeded Russian pair of Maria Kirilenko and Nadia Petrova.
The Williams sisters were seeking their 14th Grand Slam doubles title.
They hadn't played together for two years until joining up to win at Wimbledon in July, then followed that by taking the doubles gold at the London Olympics, where they beat Kirilenko and Petrova in the semifinals. Kirilenko and Petrova wound up taking the bronze.
Monday's defeat ends Venus Williams' U.S. Open. She lost in the second round of singles.
Serena Williams moved into the singles quarterfinals with a 6-0, 6-0 victory over Andrea Hlavackova earlier Monday.
