CALGARY, Alberta — Padraig Harrington made a long eagle putt on the final hole Friday for a 6-under 64 that gave him a one-shot lead over Kirk Triplett in the Shaw Charity Classic.

Triplett stated on the back nine at Canyon Meadows and was 3 under under through two holes after his birdie-eagle start.

He was a runner-up at the Shaw Charity Classic four years ago.

Paul Goydos and Robert Karlsson each shot a 66, while Matt Gogel and John Huston were another shot behind at 67.
