ANDY MURRAY blasted his poor mentality and attitude and declared: I need to start winning more matches.
The Scot – now 172nd in the world rankings – has played 13 tournaments this year but only reached the quarter-finals twice.
The 34-year-old, who served for a 5-2 lead in the first set, is hoping to finish his season with events in Vienna, Paris and Stockholm.
He said: “Sport is a results business. You need to win matches, especially if you aren’t playing your best.
“I’ve done that the last few months but not as many as I would have liked. That’s what I want. They are tough draws.
“There are no guarantees the results will come. I want to win more matches.
“Maybe more in the second set, I didn’t make enough good decisions. Mentally I was poor, my attitude was poor on the court, and those are two things you can control.”

Buenos Aires battler Schwartzman, the world no.14, grew up adoring Murray and told him so at the end.
Schwartzman, 29, said: “Like I said to Andy, it was a pleasure playing him.
“When I grew up playing tennis I watched Roger, Rafa, Andy and Djokovic. So, I tried to enjoy this match.
“Every week he is playing better and moving better.
“He is fighting, one of the best in our history. Everyone has a lot of respect towards Andy Murray.”
