Santiago, Chile (SportsNetwork.com) - Adam Hadwin birdied his final two holes on Sunday to close out a 3-under 69 and hang on for a 1-stroke victory at the Chile Classic.

Hadwin earned his first career win on the Web.com Tour at 16-under-par 272.

"It's been an amazing week for me. This is a reward for all the sacrifice and time I've invested in my game in recent years. It's my third year playing here in Chile, and now I'll take home the best memory," said Hadwin.

Alistair Presnell carded a 4-under 68 during his final round at Prince of Wales Country Club to finish in second place at 15-under 273, while Sung Joon Park (66), Henrik Norlander (69) and Kyle Reifers (71) shared third at minus-13.

Bhavik Patel (69), Andrew Putnam (70) and Scott Pinckney (72) tied for sixth at 12-under.

Hadwin entered the final round with a 1-stroke lead atop a crowded leaderboard and was quickly met at 13-under by Pinckney and Manuel Villegas, who both birdied the first.

Presnell would make it a four-way tie with a birdie at the third before Pinckney broke out of the pack with a birdie at the fifth.

Pinckney failed to hang on to the lead and bogeyed the sixth to fall back alongside Presnell and Hadwin at 13-under as Villegas fell well off the pace with bogeys at the fifth, seventh and eighth.

Park, meanwhile, was playing in one of the earlier groups of the day and countered a lone bogey with seven birdies, including his final two holes, to race into the clubhouse at 13-under.

Hadwin briefly regained the outright lead with a birdie at the ninth, but quickly gave that shot back with a bogey at the 10th.

Mulroy then joined the pack at minus-13 with a birdie at the 12th before Presnell and Pinckney both lost their share of the lead with bogeys at the 13th and 12th, respectively.

Presnell responded with an eagle at the 14th to jump into sole possession of first at 14-under, but he was soon joined there by Hadwin following a birdie at the 13th.

After Presnell bogeyed the 15th to drop out of the lead, Hadwin birdied the 14th to move to 15-under and grab a 2-stroke advantage.

Hadwin would trade a bogey at the 16th with a birdie at the 17th to remain there heading into the final hole, where Presnell had just recorded an eagle two groups prior to finish at 15-under.

Hadwin, however, calmly birdied the last from five feet to earn his 1-stroke victory.

"I played very well this week and I stuck to my strategy until the end," Hadwin said.

NOTES: Hadwin had collected two career wins on the PGA Tour Canada, the most recent at the 2011 Pacific Colombia Tour Championship ... Hadwin collected $117,000 with the victory ... Presnell had three eagles during his round.
