When Derek Chang teed off Sunday at 9:50 a.m., he was one hour in front and 10 shots behind leader Dan Woltman.

But the Dallas resident did something that only one other player has done in the 39-year history of the Southwest Kansas Pro-Am.

He shot a 9-under-par 62 at The Golf Club at Southwind, equaling the course record set in 2000 by John Bizik, who recorded the score in the opening round of that millennium year event.

Chang, who started the round tied for 19th, soared up the leaderboard as his round progressed, and finished all the way up to third at 8-under-par 206, five shots behind Dan Woltman, the wire-to-wire champion.

While his 62 isn't his all-time low competitive round — he has a 61 to his credit — the final 18 at Southwind will be a memorable one for the former Augusta State (Ga.) golfer.

"It's certainly one of my best," said a smiling Chang, who was paired with Ian Ansett and Derek Fribbs. "I got off to a great start and just tried to keep it going."

He birdied the 468-yard opening hole, eagled the par-5 3rd when he laced a 5-iron to tap-in range, and then repeated the same when his 8-iron second shot on the par-5 fifth nearly went in for a double-eagle — again just tapping in from less than two feet.

"Those were two of my best shots for sure," said Chang. "I had a lot of opportunities and just hit a lot of good shots."

Chang followed the second eagle by making birdie at the par-3 6th, and then parred the 7th, 8th and 9th to make the turn in 29 strokes.

His radar play continued by making birdies at 10, 11 and 12 to reach 9-under with six holes left.

From there, though, with the teeth of the back nine remaining, Chang could do no more than register six pars to finish out his round with an incoming 33 for his 62.

"I had some chances, but nothing fell those last holes," Chang said. "But certainly it was a lot of fun and good way to finish the tournament."

Chang said he didn't have any tournaments on his immediate schedule, but would likely find some in which to play prior to the October PGA Tour qualifying school.

UPDATE: A previous version of this article misidentified who held The Golf Club at Southwind course and Southwest Kansas Pro-Am tournament record. John Bizik had shot the course record of 62 at Southwind in 2000 in the opening round of the Pro-Am.
