Britain's Andy Murray defeated Juan Monaco 2-6 6-3 6-0 at the Shenzhen Open in China to reach his first final since winning Wimbledon last year.
The Scot had a poor start before recovering and raced through the final set against the Argentine.
He will face Tommy Robredo in Sunday's final after the Spaniard earlier beat Santiago Giraldo 6-1 6-4.
"Tommy will be a very tough opponent. I will need to play a really good match if I want to win," said Murray.
