Andy Murray says that he needs to work out what went wrong in his opening match at Indian Wells, which saw him lose to Guillermo Garcia-Lopez.
Indian Wells, the first Masters 1000 tournament of the 2012 season, has not been a happy hunting ground for Murray in recent years as he crashed out in the second round two years ago.
However the Scot admits that he was feeling much better about his game this year than he was coming in after his Australian Open final loss in 2011.
Speaking to the Daily Mail Murray said: "In comparison to how I felt coming in here last year, it's been night and day, I was feeling way more focused and confident.
"I've been practising really well so I'm going to have to go away and figure out what happened."
Guillermo Garcia-Lopez had never taken a set of Andy Murray in their previous encounters but he dropped just six games in a 6-4 6-2 victory.
Murray has looked in good form since the Australian Open, where he lost in the semi-final to eventual champion Novak Djokovic.
He got the better of Djokovic in Dubai earlier this month before losing the final to the in form Roger Federer.
However it was not all doom and gloom for the Scot as he and brother Jamie saw off fellow Brits Colin Fleming and Ross Hutchins 3-6 6-2 13-11 in the doubles.
