The RBC Canadian Open is the third-oldest event on the PGA TOUR, behind only The Open Championship and the U.S. Open. Its field also isn't lacking in star power with several players making the trip from Royal Liverpool to Royal Montreal.
Here are some groups to keep an eye on (click here for tee times):
Dustin Johnson-Brandt Snedeker-Hunter Mahan: Johnson was a runner-up in this event a year ago and last week was in contention at Royal Liverpool before tumbling to 12th on the final day. Snedeker is the defending champion and starting to regain his form after hiring Butch Harmon. Mahan, meanwhile, had the 36-hole lead at Glen Abbey last year but withdrew prior to the start of the third round to rush home for the birth of his first child. (Rd. 1 - 8 a.m. ET; Rd. 2 - 1:15 p.m. ET)
Matt Kuchar-Jim Furyk-Graham DeLaet: Furyk is a two-time winner in Canada and the all-time leading money winner in the event. He has also been in fine form with nine top 20s in his last 10 starts, which included a fourth-place finish at The Open Championship. Kuchar, meanwhile, has nine top 10s this season but none in his last five starts, though he did finish second in Canada a year ago. As for DeLaet, he'll try to become the first Canadian to win that country's Open in 60 years. (Rd. 1 - 1:05 p.m. ET; Rd. 2 - 7:50 a.m. ET)
Graeme McDowell-Luke Donald-Mike Weir: McDowell comes in on a roll with a win and two top 10s in his last three starts across the pond. Donald, not so much -- though he did finish second at the RBC Heritage earlier this year and this year's venue should set up well for him. (Rd. 1 - 1:15 p.m. ET; Rd. 2 - 8 a.m. ET)
Ernie Els-Stewart Cink-Justin Leonard: What do these three players have in common? All have won The Open Championship. None, however, have ever won this Open. (Rd. 1 - 7:50 a.m. ET; Rd. 2 - 1:05 p.m. ET)
