However, despite being 100 places below the two-time Grand Slam champion in the rankings, Edmund won through 10-7.
"I'm very happy. I knew I had to play very well to have a chance. For me to play with all these guys that I've grown up watching and been so successful has been amazing," he said during his post-match interview.
The title was the fourth that Edmund has won this year, having also triumphed in Hong Kong, the USA and Argentina.
