Murray won nearly three-quarters of the points in the match in winning 6-2, 6-0. He set off by winning the first four games and capped his third championship of 2011 by winning the last seven.
"He played well. I couldn't do much and it showed in the score," Young said after the match. "It was great play from him."
Murray dropped a total eight points over seven service games. Young managed only three points -- one on serve -- in the second set.
It was the first finals appearance for Young while Murray, who said he has his sights set on finishing the year with a No. 3 ranking, picked up his 19th career championship. He won earlier this year at Cincinnati and in London at the Queen's Club.
The first-place finish was worth $107,000 to Murray. Young collected $56,300 as runner-up and passed the $1 million mark in career earnings.
