Andy Murray says he was encouraged by his strong showing in his victory over David Goffin.
The Scot cruised through to the quarter-finals without dropping a set at the Qizhong Stadium and continued that form with a 6-2 6-2 victory over the world number 12.
Next up is either Gilles Simon or Jack Sock in the semi-finals and on current form Murray will be confident of making it into his third Shanghai final, having previously won the event in both 2010 and 2011.
Despite the convincing scoreline, Murray felt he was pushed hard by Goffin but says that overall he was pleased by how he performed against the dangerous Belgian.
"I thought it was a very good match," Murray told Sky Sports afterwards. "There were many long games on his serve that could have gone either way.
"He had a few chances on my serve, so it was a tough match. It was a pretty long one for that scoreline but I struck the ball well and created a lot of chances on my return game.
"I felt I was controlling a lot of the rallies on my forehand. “It was a good win against Goffin, who has been playing very well and had some good wins here."
