Tactically, I think played a good match and I served very well when I was behind on the games.
If this hammering had come in the earlier rounds it perhaps would have been less impressive but Dimitrov is ranked 24th in the world, beat Murray in Miami earlier this year and ousted world number three Stan Wawrinka at Cincinnati last month.
Murray was a class above against fellow seed Grigor Dimitrov, cruising to a 6-1 6-2 6-2 victory at Arthur Ashe Stadium in NY.
"I'll need to play like that again if I want to try and get the win because he is obviously one of the best players in the world and he loves these conditions". And, yeah, I mean, I always like my chances when I get to stages like that in a tournament, especially having to play, like, tough matches early on and feeling good and confident.
The Scot has still only dropped one set so far this year at Flushing Meadows but he made 63 unforced errors against Lorenzi - three times as many as he committed in either of his opening rounds.
"But that is definitely the fastest serve that I've hit".
Karlovic, 37, was the oldest man to reach a Grand Slam round of 16 since Jimmy Connors at the 1991 U.S. Open. I think it was lucky. I only did it once. I started to enjoy those butterflies before a match, complaining to your coach that you're, like, short of breath because you're so nervous to come on court.
After racing into a 3-0 lead in the next, former Wimbledon semi-finalist Dimitrov stopped the rot thanks to his first break of serve in the match, but his service game immediately unravelled, failing to capitalise on his opportunity and Murray took full advantage by steamrolling his way to a two sets to love lead.
Speaking about his next opponent, Kei Nishikori, he said, 'I have played well against him in the past. "The toughest matches are ahead for him here and he's played so much over the summer".
He was a break to the good at 2-1 in the fourth before Wawrinka, reinvigorated by a violent racquet smash courtside, recovered to win five of the next six games.
Murray on the other hand, won at the Olympics and was also knocked out by Marin Cilic at the tournament in Cincinnati, going down in the final.
The News Agency of Nigeria (NAN) reports that he became the oldest first-time champion by winning at Kitzbuehel, and adding two semi-finals and a quarter-final to his credit. "It's always something special, that's for sure", said Wawrinka, who had his left ankle taped after twisting it during the match.
But Vallverdu's presence did little to help Tomas Berdych against Murray and the Bulgarian knows how to beat Murray - and over five sets - so the simple fact is that Murray will have to play very well to win.
'Andy is the best player right now out there, ' he admitted after the match. I was quite impatient at times.
