CALGARY, Canada, Aug. 6 (Xinhua) -- Kirk Triplett moved to the top of the leaderboard after the second round of the Shaw Charity Classic on Saturday as the American carded a 2-under 68 for a one-stroke lead in Calgary, Alberta.

Through 36 holes at Canyon Meadows Golf & Country Club, the 60-year-old Triplett, an eight-time winner on the PGA Tour Champions senior circuit, was 7-under 133 at the $2.35 million tournament.

Americans Jerry Kelly and Paul Goydos tied on second with a two-round total of 6-under 134, one shot ahead of Fijian Vijay Singh. Padraig Harrington, the overnight leader, was three strokes off the pace in a group of four players as the Irishman struggled to a 2-over 72 in the windy conditions.

Triplett, who is playing in the Shaw Charity Classic for a 10th occasion, put himself in contention to win the tournament for the first time when he carded a round featuring three birdies and a lone bogey five at the 454-yard 13th hole. He called the weather a "big change" from yesterday.

"A good, stiff breeze but from the opposite direction. I think the pin placements were a little more difficult to access today, so maybe that's because I had a good round yesterday. I was playing a little more conservatively today, but I felt it was more difficult to score today."

With his first win since 2019 within reach, Triplett said his goal for Sunday's final round is trying to stay ahead of the pack.

"They keep moving forward, so I've got to keep moving forward. I can't go out there and think, 'OK, I can hit it to 30 feet on every hole and maybe make a birdie here or there and win this golf tournament'. This tour's typically about trying to find a way to shoot four-, five-under a day and that will be what I try and do tomorrow. It's worked for me in the past, that mindset, and that's what I'll be shooting for."

Kelly, who beat Triplett in a playoff at the Principal Charity Classic in June for the first of his two senior wins this year, held steady to card a bogey-free round featuring four birdies. He said he was looking forward to playing in the final group on a layout that favors long hitters.

"It's definitely fairways out here, they're running fast. These long hitters, I mean, they are literally getting it all the way to the greens. It's amazing where Thongchai's (Jaidee) hitting it, and I know Harrington's hitting it even further," said Kelly.

Harrington, the three-time major winner playing in his rookie season on the senior circuit, started the day with a bogey five and never recovered. After another bogey at the 370-yard third, he stumbled through a round that included four more bogeys buffered by four birdies.

Defending champion Doug Barron improved to a 68 to sit five shots back on tied 11th with a total of 138.
