Some dashing weekend golf by Jamie Arnold has seen the Sydneysider post his best finish of the Tour season to date as he topped the Australasians at the Chitimacha Louisiana Open.

Arnold bolted through the field on Saturday and Sunday with scores of 68-65 to climb to T11 and break a streak of three missed cuts.

Only three players went lower in the final round at Le Triomphe Golf and Country Club, Arnold’s 6-under effort leapfrogging 19 players.

John Senden, who made his first career start on the Tour and first professional start in almost 12 months, missed the cut but played some good golf in the opening two rounds as he begins his comeback to the game.

The popular Queenslander took a leave of absence in April last year when his son, Jacob, was diagnosed with a brain tumour and while the 13-year-old is not cured a positive report from doctors in January means Senden has begun the process of returning to the game.

He used one of five Tour ‘rehabilitation starts’ to which he is entitled before heading back to the main Tour next month.

After opening with an impressive 1-under 70, Senden struggled in the first nine holes of his second round and despite four birdies on his inward nine couldn’t overcome a triple and four bogeys to miss the weekend’s play.

However, he will be encouraged by much of what he saw ahead of taking his place in the field at the RBC Heritage tournament the week after The Masters.

Senden was the only one of the six Australasians in the field to miss the cut, Rhein Gibson and New Zealand’s Tim Wilkinson both climbing into the top-20 with good final rounds.

Gibson signed for a 5-under 66 to move 14 places up the standings to T16 while Wilkinson’s 4-under 67 moved him 10 places to T20.

Curtis Luck began the day in a share of fourth position after some excellent golf over the first three days but inexplicably lost his game in the final round.

A forgettable 6-over 77 dropped him to T53 and while that will be uppermost in his mind there were many positives to draw on from his play the rest of the week.
