Golf - PGA Tour update:Things haven't gone according to plan for Graeme McDowell in the last month after the US Open champion missed his third cut in four starts at this week's Zurich Classic on the PGA Tour.

McDowell's latest woes occurred at TPC Louisiana where he struggled to find form with rounds of 73, 75 to finish well down the field led by American Bubba Watson.

After starting on the back nine the 31-year-old opened with a birdie, but it was to prove a false dawn. A run of bogey, bogey, double bogey from the 13th derailed any hopes of making it into the weekend.

Despite rallying with birdies at the 16th and the second further bogeys came at the sixth and his final hole, the ninth.

It all added up to a four-over 148 aggregate and some 14 shots adrift of Watson's 10 under lead at the halfway stage.

The left-hander, winner of Farmers Insurance Open in California in January, enjoyed three birdies and an eagle at the par five 11th and dropped his only shot of the day at the 18th in a second round 68. He leads by one from fellow American Josh Teater (66) and by two from John Rollins (69) also from the States.

Luke Donald was best-placed of the European contingent after a 71 left the English golfer five under and just inside the top 10.

For McDowell it's hardly a crisis, but certainly a temporary slump of sorts following the highs throughout 2010.

The week before the US Masters he missed the cut at the Arnold Palmer Invitational at the beginning of April with rounds of 80, 73 before another early exit at Augusta after shooting 74, 73.

After a week off, McDowell returned to action on the PGA Tour at last week's Heritage but finished a lowly tied 61st, despite a promising start (68, 69, 74, 74).

Yesterday's missed cut at the Zurich Classic leaves last season's major winner with some soul-searching before he plans to tee it up in the Players' Championship at Sawgrass in a fortnight
