OAKVILLE, Ontario, July 25 (Reuters) - A star-studded group that includes Australian Jason Day and American Bubba Watson will attempt to prevent Canada's David Hearn from making history at the RBC Canadian Open on Sunday.
No Canadian has won the national golf championship since Pat Fletcher in 1954.
Hearn, however, shot a solid four-under 68 to give himself a two-shot cushion at 15-under-par 201 after three rounds at Glen Abbey on Saturday.
Day and Watson sit two shots behind the Canadian, while Americans Brooks Koepka and Michael Putnam were at 12 under. American Jim Furyk and Colombia's Camilo Villegas headline a group of five at 11-under.
