And thanks to an ace from Murray, now 6-3 4-1.
And is now headed onto RLA.
Meanwhile, Andy is up 6-3, 6-1 4-3, with a break in the third.
Serena ahead 4-1 already ....
It's getting pretty ugly out on RLA for Maria Kirlenko - she's down 6-2 3-0.
Williams 6-2 5-0. Poor Maria ...
Game set match Serena - 6-2 6-0. Just 57 mins was all it required.
Kirilenko can't get off the court fast enough. But a brief little wave to the crowd is a nice touch.
Serena: "I didn't expect to come out and play so well ... I was like, wow."
Serena's 35th Grand Slam quarterfinal
Alright poppers - time for me to sign off for a bit. The talented Mr McCarvel will take it from here while I focus on Roger, who's just arrived on RLA to massive roars from the crowd. Will we see another late-night epic? Hopefully it'll be more competitive than Serena's training drill.
Convincing start from both players on serve. The difference will be what inroads - if any - Raonic can make on the ground tonight. Roger so solid from the backcourt and working points. That's what did Raonic in a year ago when he lost to Lleyton Hewitt here. 2-1 Federer leads on serve.
WOW! 225 KMH from Raonic! OMGeez.
Raonic fights off break point there for Federer and gets to 3-all. Roger still having no trouble on his own serve, however. Tiebreak looms unless Milos cracks in next three games.
Raonic suddenly in hot water down 15-30 at 4-5, but he comes up with a good serve-and-forehand combo to get to 30-all. Federer still 2 points from the set.
And Milos double faults! Set point, Roger
And there's the set! Just like that Federer breaks for a 6-4 effort. Raonic nets a backhand volley moving forward. 33 minutes and the world No.2 up in this one.
