Final weekend to qualify for Masters through rankings

Geoff Ogilvy is out of the Masters Tournament unless he wins the Texas Open, and though he's entered in the event next week in San Antonio, it wasn't clear if he will play.

The top 50 in the world after this week are eligible for the first major of the year. Ogilvy was at No. 50, though he will fall out after missing the cut Friday at the Houston Open. Ogilvy was No. 47 after his runner-up finish at the Honda Classic, but he finished toward the bottom of the pack in his next two events, and then missed the cut his last two weeks.

Henrik Stenson is now in the best position to crack the top 50. He was at 5-under 139 going into the weekend. He could get in with a top 40 finish, though that might be depend on whether Marcel Siem wins in Morocco on the European Tour.

Augusta native Charles Howell needs to finish alone in fourth. He had 72 on Friday and was seven shots out of the lead.

Fredrik Jacobson (No. 46) and Richard Sterne (No. 48) are the other golfers who will get a berth into the Masters if they remain in the top 50.
