The conclusion of the Shell Houston Open meant the finalizing of the Masters field (except for the spot saved for the winner of this week's Valero Texas Open, provided he is not already invited).
Among those who locked up spots in the World Ranking's top 50 was Henrik Stenson, whose final-round 66 earned him a T-2 at Houston, where he needed to finish no worse than solo 13th. Fredrik Jacobson and Richard Sterne have also earned trips to Augusta, despite neither having played last week.
Narrowly missing out on a spot was Augusta native Charles Howell II, who needed to finish fifth in Houston but finished T-10, with middle rounds of 72-70 hurting his cause.
Marcel Siem, who won the European Tour's Trophee Hassan II, temporarily sat inside the top 50 (at No. 49) but was edged by the finishes of Stenson and Russell Henley. The latter shot 68 Sunday in Houston, where a T-45 landed him No. 50 on the ranking, .0251 points ahead of Siem.
Former U.S. Open champ Geoff Ogilvy, who began his week at No. 50, missed the cut in Texas, dropped outside the magic number and withdrew from this week's San Antonio event after playing 10 of the last 11 weeks.
