Sweden's Henrik Stenson birdied four of the last five holes to seize the clubhouse lead when a thunderstorm halted play on Sunday in the final round of the $6.2 million PGA Houston Open. Stenson, a former top-five player whose effort will enable him to qualify for the Masters, fired a six-under par 66 to finish 72 holes on 15-under 273. "To be heading back to Augusta is really special for me. I'm extremely happy with what I've done," Stenson said. "It's a very pleasing finish to birdie four of my last five holes. I played some great shots coming down the stretch."

Germany's Marcel Siem extended his Trophee Hassan II lead to four shots on Saturday as a third round 69 also kept alive his hopes of making a maiden Masters appearance. The 32-year-old Siem, who needs to win on Sunday to climb into the world's top 50 and earn a ticket to Augusta, finished the day on 15 under par, a round boosted by four birdies in six holes around the turn at the Golf du Palais Royal. Spain's Pablo Larrazabal, 2011 champion David Horsey of England and Finland's Mikko Ilonen are all grouped in second place.
