I've been Amee Ruszkai and stayed tuned for my follow-up report of the match this afternoon.
That's it! Thank you for joining me today for the live commentary of Murray's victory over Pospisil on Centre Court in the quarter-finals of Wimbledon 2015.

Interesting comparison of Karlovic's and Pospisil's serves shows that the Croat's height allowed him to generate an average of around 40cm more height on the bounce. Pospisil's serve much easier for Murray in comparison given the height at which he receives it.
He breaks! Murray leads 2-1, nine minutes played. Great start for the Brit.

Murray's own serve works well too though as he gets three of four in first time and also manages a love service game. 1-1.
Looks like the Canadian can keep up with the Brit on these rallies. Will be interesting to see whether or not fatigue comes into play later in the match to affect this.
Some strong serving and some lovely volleys give Pospisil the first game, with a winner on a rally as well. Love service game. 1-0.
Will be intriguing to see how Pospisil deals with the occasion too. He is serving the first game of the day now.
Murray had plenty of practice in the last round against a good serve playing Karlovic so it will be interesting to see what Pospisil does if his serve does not have a great effect today.
Pospisil's strength is his serve, yet one of Murray's biggest strengths is his return. Sure to be an enthralling match as a result.

All the stars are awaiting the arrival of Murray and Pospisil on Centre Court. David Beckham and of course Prince William and Kate Middleton just a few of those watching on. Players will be on court shortly.
Murray will head into the match hoping to get some sort of revenge for his compatriot, Ward, whilst Pospisil will be hoping to cause his third upset of the tournament and turn the home fans on him once more at Wimbledon 2015.
Murray and Pospisil have played each other a total of just three times in their careers, with all of those coming in the last year. As aforementioned, these were all played on hard court, with Murray the winner each time in straight sets. Their latest meeting came in February of this year as they met in round two of the ABN AMRO World Tennis Tournament, the Brit winning 6-3 7-5.
Pospisil admitted that he is "not worried about" the hostile crowd that awaits him either as things like that don't "really faze [him] too much" and he likes "playing in front of big crowds in general," regardless of whether "they are against [him] or cheering for [him]."
Speaking about Murray as an opponent, Pospisil acknowledged that the match will "obviously [be] a tough one" as the world number three has had "great results [at Wimbledon] over the years," and because he's "one of the big four." However, the Canadian believes that he is "serving well" and "playing well" and aims to go out on Centre Court today to "play to the best of his abilities."
Pospisil spoke about how he feels that he is "stepping up [his] game" too and that he is "more ambitious than ever right now," citing certain new mental practices as reasons for his improvement.
Pospisil responded to Murray's suggestion of the Canadian potentially experiencing fatigue in his own press conference following victory over Troicki, saying that whilst he has "played a lot of tennis," a "one day recovery is a lot" and thus he will be ready to "come out strong [today] and take [the match] to him."
He also said that his shoulder "feels better" after a few days rest following it's occurrence as a problem against Seppi in round three. Though Murray admitted that he "would have liked to have served a little bit bigger" and "a little bit harder" against Karlovic, he is "still conscious of the problem," but told the media that it "feels better than it did three, four days ago, which is positive."
As for how Murray feels himself, he said he is "feel[ing] pretty fresh" after the Karlovic match as, "although [it] was quite long," he insists that it was "not as physical" as others because "the rallies aren't particularly long."
Still, the Brit has stressed that he will not "bank on that being the case." He will look to use Pospisil's fatigue "to [his] advantage" if it is apparent, but is not entering the match expecting an easy run in against a tired opponent.
Murray is also aware that Pospisil "can play well on [grass]", with him having "had a good run" at Wimbledon this year and also winning the doubles last year. However, he knows Pospisil has played "a lot of tennis" so far at Wimbledon 2015, which can be "a positive for him in some ways," but Murray is likely to be hoping that the possibility of his opponent "maybe [being] a little bit fatigued" will be the case and work in his favour.
One of the main reasons for this is the "different surface." The Brit is aware that he has played his next opponent "three times on the hard courts," with "a couple of them" even being "indoors," so playing him "on grass" will be very different.
Speaking after this win and ahead of his clash with Pospisil, Murray acknowledged that whilst he has played Pospisil three times in the last 10 months, their match today will be far different than the others.
Murray's marvellous return came in handy in the match and was a key factor as he steered himself to victory in just four sets, the final score reading 7-6 6-4 5-7 6-4 in a truly enthralling encounter.
The world number three was back to showcasing his good side in round four though as he came up against big server and 23rd seed Ivo Karlovic, who had already beaten the likes of Alexandr Dologpolov and Jo-Wilfried Tsonga in the tournament so far.
Murray then brought the trainer on himself to inspect and help a shoulder problem, before going on to win the fourth set, also 6-1, and take the match, with the trainer's mysterious magic the big headline in an encounter that really showed the two sides of Britain's best hope of a Wimbledon winner this year.
Two sets down, Seppi brought the trainer on to treat his knee area during a medical time out, and this pause and time to concentrate worked wonders as the Italian suddenly brushed Murray aside in set number three, winning it 6-1.
These same levels of incredible performance were displayed in round three as well, with Murray racing into a two set lead against 25th seed Andreas Seppi in outstanding time, however, he would endure a serious blip and drop his first set of the tournament shortly afterwards.
The British number one was simply ruthless in his first two rounds of the tournament, dispatching Mikhail Kukushkin of Kazakhstan and Dutchman Robin Haase with relative ease, both matches won in straight sets.
Murray will be Pospisil's hardest challenge yet though, the third seed coming into the match in great form, arguably the best form he's produced since he won the Championships in 2013, and with a very vocal home crowd behind him.
Still, by eliminating the likes of Troicki, Fognini and the inspired Ward, Pospisil has certainly shown his quality and will be a tough test for Murray today.
Pospisil has been a touch lucky in his run though, with David Ferrer dropping out of the tournament before it had even begun and Rafael Nadal being knocked out by Dustin Brown - both Spaniards being players the Canadian would have had to face, surely, otherwise.
Challenges continued to come for the world number 56 and in the fourth round he faced 22nd seed Viktor Troicki, a man who reached the semi-finals at Queens prior to Wimbledon 2015. Five sets were again required to separate Pospisil and his opponent, and the Canadian came from two sets down this time to continue his best ever run in SW19.
The third round required Pospisil to defeat British wildcard James Ward, who broke into the top 100 with his second round victory over Jiri Vesely. On Court Number One, the Canadian faced a very hostile crowd but came through in dramatic fashion, winning the fifth set 8-6 to propel himself into the last 16.
Round two was then shorter in terms of sets, but tougher in terms of the opponent as Pospisil beat 30th seed Fabio Fognini 6-3 6-4 1-6 6-3 to cause a real upset in the bottom half of the draw.
Round one seemed straight-forward for Pospisil as he faced Vincent Millot, but the French qualifier really made him work for the victory as the match went all the way to five sets, with three of these decided on a tiebreak.
Pospisil has been a huge surprise package at this year's finals, disposing of two seeds and a home favourite on his way to the last eight, with the latter an achievement he will want to repeat as he faces Murray today.
