Murray puts Britain in front
Great Britain moved into a 1-0 lead in their Davis Cup World Group first round tie with the USA after Andy Murray eased past Donald Young.
The British No 1 was totally untroubled by Young on the clay courts of Petco Park in San Diego as he completed a 6-1 6-2 6-3 victory in an hour and 38 minutes.
Murray dominted from the start and was 5-0 up with the first set just 16 minutes old before Young avoided a bagel by finally holding serve.
But Murray wrapped the set up in the next game and broke Young's serve twice more to take complete control of the second set.
Murray took the set to go two-up before the hour mark and got across the line with ease in the third set despite the fact Young managed to hold serve three times.
Friday's other singles rubber sees American No 2 Sam Querrey take on James Ward.
"It's important to get off to a good start. In the two singles matches I'm obviously going in as favourite and Sam will be going in as favourite against James," Murray said on Eurosport.
"It puts the pressure on Sam a lot now to play a good match and James can hopefully go out there and play a little bit freer. It was a good start"
He added of the court: "It's still pretty slippy and it's tough to change direction but you can see the conditions today - it's been raining in the evenings, it's cold and there is a lot of cloud cover so the court is obviously going to play slower because of that."
