Irish golf ace Padraig Harrington says he isn't worried about his performance, despite a worrying start to his season.

He disqualified in Abu Dhabi, then his first round defeat in the WGC-Accenture Match Play Championship followed after three poor finishes in stroke-play events.

Having finished 58th in the Volvo Golf Champions in Bahrain, he then tied at 63rd in the AT&T Pebble Beach National Pro-Am, slipping to 55th in the Northern Trust Open in LA last week.

Now down to 35th in the world rankings Harrington is still convinced it's only a matter of time before he gets results.

"I've no concerns. It's all good. Very good actually. Results? Okay, they haven't been good so far, but I have only played a few events," he told the press this week.

"I just need to stay patient and let it happen. Everything is in good stead."
