Dick Mast took the first-round lead Friday in the Champions Tour's Montreal Championship, shooting a 3-under 69 on La Vallee du Richelieu's difficult Rouville Course.
The 62-year-old Mast, winless on the 50-and-over tour, had five birdies and two bogeys.
Kenny Perry, the Senior Players Championship and U.S. Senior Open winner in consecutive tour starts this summer, opened with a 70 on the tree-lined layout. Bernhard Langer was another stroke back along with Mark Brooks, Mike Reid, Tom Pernice Jr. and David Frost.
Mark Calcavecchia, the winner last year on the adjacent Vercheres layout, had a 74. He missed the tour's previous two events because of back problems.
Rocco Mediate, coming off a blowout victory Sunday in Calgary, Alberta, opened with a 75. Last week, he shot 63-64-64 for a seven-stroke victory.
