Ogilvy, Chalmers, Fraser eye US Masters Geoff Ogilvy, Greg Chalmers and Marcus Fraser are confident of boosting Australia's meagre representation at next month's Masters as crunch time looms for invites. So far only Adam Scott, Jason Day, Marc Leishman and John Senden are assured of playing the year's first major championship at Augusta National on April 11-14. Ogilvy (50th), Chalmers (60th) and Fraser (61st) have less than two weeks left to find themselves inside the world's top 50 on April 1 to earn an invitation. All three tee it up in big events this week trying to secure much-needed ranking points. Ogilvy, aiming to appear in his eighth consecutive Masters, has slipped from 47th to 50th in the last two weeks since his runner-up finish at the Honda Classic. "I'm trying not to look at the points even though I'm aware I need a few more to lock it up," Ogilvy said. I said earlier in the year I am going to play until I am in the Masters and I'm still playing and hopefully I can win this week and we don't have to worry about it anymore. This is as good a week as any and I'm excited about it and remain confident. Ogilvy joins Chalmers, who is fresh off a tie for fourth at the Tampa Bay Championship, in this week's Arnold Palmer Invitational in Florida. Fraser is teeing it up in the Malaysian Open on the European Tour. Of the five players ahead of Ogilvy in the rankings, only 46th-ranked Fredrik Jacobson of Sweden isn't playing somewhere, meaning a good result is needed to push up. After fading on the weekend in Tampa, Ogilvy now has plenty of others, including Fraser and Chalmers, breathing down his neck and says there's "no chance" he'd even watch the Masters if he's not part of the field. Chalmers added this week's event to his schedule for the world ranking points on offer, changing from the recent Puerto Rico Open. If you're not confident after a week like last week what's the point? Chalmers said. I knew my best chance to run the roulette table for the Masters was playing well here and the next two weeks before the cut-off represents a great chance for me to get over the hump. Robert Allenby, Stuart Appleby, Aaron Baddeley, Scott Gardiner, Rod Pampling, Matt Jones, are also playing in Florida this week, along with Day, Senden and Leishman, and those seven need a victory to secure a Masters start. To claim the title at Bay Hill, first they must get past raging hot favourite Tiger Woods. The reigning champion has a record seven titles in the event and is short priced to make it eight after winning two weeks ago at the World Golf Championships Cadillac Championship. If Woods does take the title, he will return to world No.1.
