Donald Young has been included in the USA squad for next month's Davis Cup tie against Great Britain.
In recent outings, Sam Querrey had played in the singles alongside big-serving John Isner.
However, captain Jim Courier has selected 25-year-old Young for the clash in Glasgow, with Isner and the Bryan brothers Bob and Mike making up the team.
Earlier today, British skipper Leon Smith announced his four-man lineup, which included Andy Murray and his elder sibling Jamie.
The tie will get underway on Friday, March 6.
