Both times, he watched an Augustan keep the trophy at home. Now, it's his time to try to match what Michael Green (2004) and Chase Parker (2008) pulled off.
Sigg opened with 2-under-par 68 to find himself in contention after the first round Monday.
"I had a lot of pressure riding on me," Sigg said. "But I knew I'd come out here and play good."
Macon's Seth Sanders, who birdied four holes during a six-hole stretch starting at No. 5, surged into the lead with 66. Christopher Guglielmo, of Cumming, is one shot back. Acworth's Michael Hines is tied with Sigg for third place.
Jack Gibbs, of Evans, one of Sigg's fellow Augusta Country Club members, opened with 73. Emmanuel Kountakis, of Martinez, birdied Nos. 1 and 2 en route to shooting 3-under on the front nine and finished with 73.
"I know I can go low out here," said Kountakis, who played Augusta Country Club for just the third time. "In order to have a good chance of winning, I've got to go low (today)."
Sigg hopes to continue his hot stretch this week. Sigg, who will be a junior this fall at Richmond Academy, shot 69 to finish runner-up in the Class AAA state tournament in May. Later that month, he rebounded from an opening 74 with rounds of 69-68 to finish sixth in the Augusta Country Club championship. Last week, he finished third in the American Junior Golf Association's Burgett H. Mooney Jr. Rome Classic.
Sigg has always been a solid striker, but his game really improved over the past year when he began focusing more on his short game.
"I've just really worked on my putting a lot," he said. "And my speed on the greens this year is a lot better this year."
Sigg opened the first round with a pair of pars before running in a 15-foot par putt at No. 3. He knocked an 8-iron to tap-in range for his first birdie at the par-5 eighth. After a bogey at No. 12, he fired an 8-iron to four feet for birdie at 14. He hit a sand wedge to 10 feet for another birdie at the 17th.
If he can continue to play well in the second round, Sigg will give himself a chance to win his first major Georgia State Golf Association title.
More importantly, he's looking for an opportunity to keep the trophy in Augusta.
"It'd mean a lot to keep the tradition alive," Sigg said. "It'd be good for the club as well."
