Tom Watson had a bogey-free 68 to move into contention. Americans filled six of the top nine places, improving the likelihood of an eighth American winner in nine years.
Defending champion Bernhard Langer faded with a 76, nine shots off the pace.
Fowler, a two-time winner on the Senior European Tour this season, holed a pitch shot for birdie on No. 16. England's Kevin Spurgeon had the low round with eight birdies for a 66.
Bob Tway (70) and 2010 runner-up Corey Pavin (72) were tied at 3 under with England's Barry Lane (70).

VANCOUVER, British Columbia (AP) - Michael Thompson followed up his even-par opening round with a 4-under 66 to move into a tie with fellow American Chad Campbell after the second round of the RBC Canadian Open.

Paul Goydos (69) and Lee Janzen (68) had a share of the lead before bogeys on their final hole dropped them to 137 after another tough day in the thick rough along the tight, tree-lined Shaughnessy Golf and Country Club.
Masters champion Charl Schwartzel (67), Geoff Ogilvy (68), Rickie Fowler (69), Jerry Kelly (67), Canadians David Hearn (68) and Adam Hadwin (66), and first-round leader Kris Blanks (71) were at 2 under.
