Australian trio Rod Pampling, Robert Allenby and Nick O&aposHern finished in a share of third place but it was rising star Anthony Kim&aposs day as he rallied to win the AT&T National at Congressional Country Club. Just over two weeks after turning 23 years old, Kim was three shots off the lead at the start of the final round. However, he was undeterred by the deficit as he shot a bogey-free, five-under-par 65 to finish at 12-under overall and win by two strokes over Sweden&aposs Fredrik Jacobson. Kim became the first American under 25 to win on the PGA Tour twice in the same year since Tiger Woods, the tournament host who is out for the remainder of the season after undergoing reconstructive knee surgery. In early May, Kim won the Wachovia Championship for his first career title. The victory also moved Kim into sixth place in the Ryder Cup standings and will likely move him into the top 10 in the world. There was a six-way tie for third with Jim Furyk (66), Dean Wilson (67), Tommy Armour III (69) and Pampling (65), Allenby (67) and O&aposHern (69) all at 271. Third-round leader Tom Pernice Jr stumbled to a disappointing 72 and finished in a tie for ninth. It was the first time Pernice held a final-round lead since the Buick Open last year, where he struggled to a 75 en route to slipping all the way to 20th. Pernice opened with a birdie Sunday to take a two-shot lead, but it all was downhill from there. By the fifth hole, he found himself in a tie for the lead, then fell out of the lead following a double-bogey at the par-four sixth. He sent his tee shot into the water at the par-three 10th, settling for another double-bogey. Just to garner a top-10 finish, Pernice needed to birdie three of his final four holes. A big-hitter, Kim had such struggles, opening with a birdie at the par-four first hole and adding two more on the front side at holes seven and nine, making the turn in 32. Kim continued his flawless play, sinking a short birdie putt at the 10th and another at the par-five 16th. Pernice was pleased with his display but rued some missed opportunities on the greens. “The last 12 or 13 holes, I hit the ball really nice and gave myself a lot of opportunities, but just didn&apost hole any of the putts,” Pernice said. “My speed was a little bit off, which caused me to miss some. I misread a few, and some of the putts, when you get above the hole are pretty tricky here.” The 48-year-old dipped under par for the round with a birdie on the penultimate hole, securing his slender advantage going into Sunday&aposs final round.
