Louis Oosthuizen made another fast start to his first tournament of the year, shooting a 7-under 65 in the first round of the Qatar Masters to share the lead with Pablo Larrazabal on Wednesday.

The 2010 British Open champion has won his first event of the calendar year in four of the last five years, and in Qatar he rolled in seven birdies in a bogey-free round.

Larrazabal also made seven birdies and no bogeys at Doha Golf Club, where 36 players broke 70 despite the windy conditions.

Andrew Johnston and Nicolas Colsaerts are a shot behind along with Sweden's Bjorn Akesson, who was 7 under after 11 holes but bogeyed No. 8 — his 17th hole.

Defending champion Branden Grace and 2014 winner Sergio Garcia shot 70s.
