Two-time Grand Slam champion Andy Murray has wished Mardy Fish good luck for the US Open after admitting that he is one of the Scotsman's "trickiest opponents".
The 2013 Wimbledon winner executed a 6-4 7-5 victory over the American to reach the third round of the Cincinnati Masters on Thursday.
After the result, Murray tweeted: "One of my trickiest opponents good Person, fun guy who's been very unfortunate these last few years... All the best for the us open and your life after tennis!"
Last weekend, Murray beat Novak Djokovic in three sets to win the Rogers Cup.
