Andy Murray has described his defeat to Jo-Wilfried Tsonga at the Rogers Cup in Toronto as "disappointing".
The British number one lost 7-6 4-6 6-4 yesterday evening in the quarter-final of the event, which was his first competition since Wimbledon.
He told Sky Sports News: "It's just disappointing because it's important to play matches.
"If you've had a break for a while, ideally you want to try and play as many matches as you can.
"Tennis and sport really can change a lot from one day to the next. Jo is a top player. He's a fantastic athlete. When his game is on, he's very tough to beat."
Tsonga will face Grigor Dimitrov in the semi-finals later today.
