Blake, US start strong
Blake is in a three-way tie at the top of the leaderboard alongside Germanyís Bernhard Langer and Englandís Carl Mason.
Below that trio the only non-American in the next 17 places was Scotsman Sam Torrance, who shot a 69.
Carnoustie, widely rated as the toughest links layout on the British Open championship rotation, is vastly different from most of the courses on the Champions Tour.
ďItís a golf course where you canít be aggressive because you canít fly the ball at flags like we are used to over in the courses we play in America,Ē said Blake, who had six birdies and two bogeys. ďI have had to learn a whole new game, which is fun. Itís exciting, but itís tough.Ē
Among the Americans chasing the leaders were U.S. Ryder Cup captain Corey Pavin (69) and former captain Tom Lehman (71).
Delahoussaye shoots 62 in Canadian Open
At Toronto, Brent Delahoussaye shot an 8-under 62 on Thursday to match the Canadian Open record, making an eagle, seven birdies and a bogey in perfect scoring conditions at historic St. Georgeís.

Delahoussaye, 29, also broke the course record of 64 set by Canadian George Knudson in 1968.
Vance Veazey and Brock Mackenzie opened with 64s.
Oosthuizen tied for lead
At Stockholm, British Open champion Louis Oosthuizen shot a 5-under 67 and was tied with Australiaís Richard Green and Dustin Johnson of the United States after the first round of the Scandinavian Masters on Thursday.
