On Sunday, the 2010 British Open (ESPN, 8:00 A.M. Eastern) comes to an end at the Old Course in St. Andrew's, as Louis Oosthuizen will try to parlay his tournament lead into not only his first major win, but his first PGA Tour win.
Entering Round 4 play, Oosthuizen holds a four-stroke lead. He's played largely mistake-free golf in this tournament, having committed only four bogeys through the first 36 holes, so it will likely be up to his competitors to score their best rounds of the tournament and hope that Oosthuizen doesn't have another Round 1.
Oosthuizen's greatest threat is Paul Casey, whose Round 3 score of 67 bested the South African's 69. Casey enters Round 4 at 11-under. Behind them are Martin Kaymer (-8) at third place, and Alejandro Canizares, Lee Westwood, and Henrik Stenson (-7) in a three-way tie for fourth.
The wind factor doesn't figure to be as influential as it was earlier in the tournament, but it may turn into a wet affair. The Weather Channel's forecast:
Cloudy with occasional rain showers. High around 60F. Winds SW at 15 to 25 mph. Chance of rain 60%.
The first group tees off at 2:25 A.M. Eastern. Here are Round 4 tee times for the top pairs:
8:05 AM Sergio Garcia, JB Holmes
8:15 AM Ricky Barnes, Rory McIlroy
8:25 AM Retief Goosen, Sean O'Hair
8:35 AM Nick Watney, Dustin Johnson
8:45 AM Lee Westwood, Alejandro Canizares
8:55 AM Henrik Stenson, Martin Kaymer
9:05 AM Paul Casey, Louis Oosthuizen
