Andy Murray will face Donald Young to open Great Britain's Davis Cup tie against the United States, which begins Friday in Glasgow, Scotland.
It seems likely Murray will focus on singles play in the competition, but he isn't ruling out a doubles match if needed.
Murray is No. 5 in world rankings, making him the best player in the weekend's best-of-5 competition. Young is playing well and is No. 47.
Play each day begins at 8 a.m. ET. TV coverage is by The Tennis Channel.
Great Britain's other singles player in James Ward, who enters as a decided underdog against the United States' best player. John Isner is No. 20; Ward is No. 111.
After Friday's singles matches, Britain and the U.S. send out their doubles teams. Americans Bob and Mike Bryan are the world's best pair, meaning Britain faces long odds of winning with its doubles players Jamie Murray and Dominic Inglot.
Jamie is Andy's older brother. Inglot has beaten the Bryans twice this year when paired with Romania's Florin Mergea.
If matches follow form, it's likely Britain will enter Sunday's final matches needing to win both singles. That's why observes whether Leon Smith, who is Britain's captain, might have Andy Murray play doubles.
"I would say it's unlikely that I would play the doubles on Saturday," Andy Murray said, according to the BBC. "If it's required then it would be nice to play with Jamie or Dom.
"Whichever team Leon picks will have an opportunity of winning the match provided they play great tennis."
U.S. captain Jim Courier knows Murray is 19-2 in Davis Cup play, and that the U.S. lost to Britain 3-1 last year in San Diego.
Young lost to Murray last year 6-1, 6-2, 6-3,, so U.S. hopes hinge on Isner winning twice and the Bryan brothers winning. Smith knows the challenge.
"Isner is a top 20 player, has been top 10 before and is a different caliber to what came out at us last time," Smith said this week.
"They definitely go in as favorites on rankings. They have the Bryan brothers who are the best doubles team to ever walk the planet so somewhere along the line we are going to have to get an upset, that is the reality of it. It is a big challenge but one that hopefully we can do at the weekend."
Observers believe the U.S. made a mistake last year by playing on clay. Glasgow's indoor hard surface should be much better for Isner, who at 6-10 is a power player.
Isner didn't play last year. Britain won because Ward upset Sam Querrey 1-6, 7-6(3), 3-6, 6-4, 6-1 before Murray beat Querrey in four sets to seal the tie.
Young is in much better form entering this weekend, having reached the semifinals at Memphis and the finals at Delray Beach in his previous competitions.
Young is ready.
"Now I feel a lot more comfortable and confident than I was last year. That was my first Davis Cup match, so I had a ton of nerves at the start of the match," he told TennisLive.com.
"It was always going to be tough, anyway, because he's a great player. But I feel better and more confident now."
