Andy Murray steered Scotland to a second Aberdeen Cup title as the home side thrashed England 6½-1.
Murray got the better of Rusedski to secure a win for Scotland
Britain's number one rounded off the two-day event by beating Greg Rusedski for the second time with a 6-3 6-4 win.
But Murray, who has a persistant ankle problem, questioned the state of the Aberdeen court.
"The court is dangerous to play on," he said. "It's slippy and the line judges are very close to the back so I could have comfortably twisted my ankle."
Murray, and his brother Jamie, made Scotland's triumph safe in Sunday's first tie, defeating Rusedski and James Auckland 6-4 3-6 13-11 in the doubles.
Elena Baltacha and Jamie Murray then gained a point in the mixed doubles while the juniors added half a point.
On Saturday, Murray had edged out Rusedski in a close-fought affair 6-4 3-6 6-4.
The British rivals were tied at one-set all but Murray broke in the 10th game of the third to seal the win.
Murray, the world number 17, got the better of Rusedski, 33, when play resumed on Sunday in the men's doubles.
Rusedski was broken to love at 4-3 in the opener and Murray survived a break point at 5-4 to serve out the set.
The court here is dangerous to play on
The English duo rallied to break the Scottish brothers in the eighth game of the second set with Auckland holding his nerve to level the match.
But the Scots clinched the victory in the tie-break thanks to a volley from Jamie Murray.
When they returned to court to finish off the weekend's events, Murray and Rusedski exchanged breaks in a nervy opening.
Murray made the decisive break in the eighth game and served out the set.
Rusedski tried to put the teenager under pressure in the second, taking him to 0-40 only for Murray to recover and hold at 2-2.
The Scot then gave the Aberdeen crowd something to cheer about as he broke again and quickly wrapped up the match.
Baltacha made a successful return after six months on the sidelines
Rusedski was in good spirits, despite losing all three matches in Aberdeen, and was looking forward to taking a break.
"I really enjoyed myself this weekend," said Rusedski. "Physically it felt good and I'm looking forward to coming back here in 12 months' time.
"Now I'm looking forward to Christmas with my family as opposed to preparing for the Australian season."
The tournament also saw Baltacha complete her successful comeback from surgery to correct a prolapsed disc.
First she beat Katie O'Brien 6-7 6-1 10-2 in the singles, and then she teamed up with Jamie Murray in the doubles to beat O'Brien and James Auckland.
Scottish juniors Caitlin Steel and James McKie won both their singles and doubles matches to add half points to Scotland's score.
Auckland won England's only point by beating Jamie Murray 6-3 6-7 10-7 on Saturday.
