The win lifted Murray to eighth in the Race to London standings with the top eight players qualifying for the prestigious season-ending tournament from Nov. 9-16.
The 27-year-old reached his 44th ATP final with a sixth consecutive win over Troicki, wrapped up in 83 minutes.
Murray will face either top seed David Ferrer, of Spain, or Germany’s Philipp Kohlschreiber, who meet later on Saturday for a place in the final.
“I need to play well on some key points,” Murray was quoted as saying by the BBC.
“Whomever I play in the final, it won’t be easy. David will be tough for sure, he’s very motivated, like myself, for London.” -Reuters
