( CNN ) -- South African pair Louis Oosthuizen and Charl Schwartzel put their Augusta disappointments behind them to impress in the opening round of the Malaysian Open Thursday . Schwartzel finished 18 shots off the pace in his defense of the U.S. Masters crown , handing over the Green Jacket to Bubba Watson , who beat Oosthuizen in a dramatic playoff Sunday . Shrugging off jet lag after a 30-hour journey from Georgia to Kuala Lumpur , Schwartzel powered to an eight-under 64 to claim the first day lead . Oosthuizen , so close to winning a second major title until denied by Watson 's brilliance , produced an excellent 66 to be tied for third . `` Louis and I got off to a good fast start at the beginning and it is always nice when there are a couple of you in the group playing well and pulling each other a long a bit , '' Schwartzel told the official European Tour website . `` Louis is playing so well right that it is impressive to watch and helped me on , '' he added . Oosthuizen conjured up six birdies and an eagle to continue the fine form he displayed in the first major of the season . `` It was a long haul getting here , '' he said . `` I think me and Charl knew the first round , concentration levels wo n't be great , but we did well . `` I knew the swing was still good . It was just adapting to the weather and the green speed , but I putted beautifully again today and hope to keep it going for the week . '' Schwartzel is seeking his first win since claiming the 2011 Masters title and has a one-shot lead over India 's Jeev Milka Singh . Oosthuizen is bracked with American Jason Knutzon and India 's Jyoti Randhawa . Defending champion Matteo Manassero of Italy and seventh-ranked Martin Kaymer of Germany both shot two under par rounds of 70 to stay in contention . On the PGA Tour , world number one Luke Donald made a poor start to The Heritage tournament at Harbour Town in Hilton Head , carding a four-over-par 75 . Chad Campbell , Vaughn Taylor and Colt Knost shared the lead on four-under 67 .
