Here are some things You Oughta Know for Sunday's final round of the DP World Tour Championship as the European Tour season comes to a close in Dubai:
• Co-leader Luke Donald carries a streak of 100 holes on the Earth Course without a bogey into Sunday's final round. The Englishman is 32 under across that stretch and seeks to become the first to win a European Tour event without recording a bogey since Jesper Parnevik won the Scandinavia Masters without a blemish in 1995.
• Sharing the lead with Donald, Rory McIlroy will play with Titleist clubs for the last time in competition Sunday, as his equipment contract with the manufacturer is set to expire at year's end. The Ulsterman appears on the verge of yet another worldwide top-5 finish, which would be his ninth such result in only 15 starts this season on the European Tour.
• Louis Oosthuizen continues to compile an impressive second half to his 2012 campaign. A runner-up in Singapore earlier this month, Oosthuizen shares third place with fellow countryman Charl Schwartzel after 54 holes and is in position to record his fourth consecutive top-10 finish on the European Tour.
• Sergio Garcia's scorecard this week shows what a difference a day can make. Making his first start since the Ryder Cup, Garcia played the final two holes Friday in five shots – a birdie 2 on the 17th, followed by an eagle 3 on the home hole. A day later, he needed 12 shots to play those same two holes, carding a pair of double bogeys. As a result, he Spaniard will begin the final round 11 shots off the pace after a third-round 73.
• Branden Grace has one round left in a rookie season that he has described as "a dream come true." After earning his card at Q-School a year ago, the South African leads the European Tour with four wins this season. He starts the final round at Jumeirah Golf Estates in a tie for fifth, five shots behind Donald and McIlroy.
• Frenchman Romain Wattel is giving his frequent flyer account a workout as he looks to secure playing status for 2013. After making it through the second stage of PGA Tour Q-School on the number last week, Wattel flew from California to Dubai for this week's European Tour finale. At 11 under, he shares seventh place after 54 holes and appears in position for a solid finish before flying back to California for the final stage of Q-School next weekend.
