Britain's Andy Murray eased into the third round of the U.S. Open for the seventh consecutive year with a straight-sets victory over Ivan Dodig, according to BBC Sport.
He outclassed the unseeded Croatian 6-2 6-1 6-3 in a hugely one-sided match lasting an hour and 50 minutes.
Murray, 25, followed up his erratic first-round win over Alex Bogomolov Jr with a clinical display on Arthur Ashe Stadium.
He will meet Pablo Andujar or Feliciano Lopez, both Spaniards, in the last 32.
The third seed produced 10 aces and 30 winners and said afterwards that he was pleased to have improved on his patchy opening performance against Bogomolov.
"I thought I played well," said Murray. "There were a lot of long rallies. I moved my feet pretty well. They were definitely easier conditions to play in, compared with the other day when it was windy. I served better. I've got a couple of days to work on some things and I've got to get used to playing in the day, so I'll get out there in the heat."
Dodig, who was on the verge of breaking into the world's top 30 before a back problem hindered his progress and caused him to plummet to 118th in the rankings, rarely troubled the Scot.
Within 70 minutes the British number one had a two-set advantage and victory never seemed in doubt, especially after he broke early in the third for a 3-1 lead.
