LONDON (AP) _ Colin Montgomerie's double bogey on the 18th hole at Winged Foot that cost him the U.S. Open championship hasn't dented his confidence.

Montgomerie, back in action on the European Tour this week at the Johnnie Walker Championship at Gleneagles, Scotland, said Tuesday he feels he can still win a major.

Next up is the British Open at Royal Liverpool from July 20-23, Montgomerie's 59th attempt at winning a major.

``I'm going to Hoylake to the Open next month full of confidence,'' Montgomerie, who turns 43 on Friday, told Britain's Sky Sports News television.

``It is tight off the tee and you have to position your ball from the drive. The greens are pretty flat so it should suit me.

``I finished second in the Open last year (at St. Andrews), have finished second in the U.S. edition and one day let's hope the door is open. It was open last week but I didn't walk through it.''

Even a bogey on the final hole would have advanced Montgomerie to an 18-hole playoff with eventual winner Geoff Ogilvy of Australia.

Montgomerie has had playoff losses in the 1994 U.S. Open (against Ernie Els) and 1995 U.S. PGA (Steve Elkington), as well as another second-place finish in the 1997 U.S. Open (again to Els).

``It has been a tough couple of years and it is just a question of giving yourself opportunities,'' Montgomerie said. ``I had a chance at the weekend and hopefully I will have chances in the future. This ranks as my No. 1 disappointment because it was my fault this time.''
