Jackson Koivun Goes Unbeaten in Presidents Cup Debut at Medinah

Jackson Koivun was the only player on either team to leave Medinah Country Club unbeaten, a result that backed up U.S. captain Brandt Snedeker's decision to add the 21-year-old to his Presidents Cup roster as a captain's pick.

How did Koivun close out his singles match?

Koivun beat Si Woo Kim, one of the Internationals' top players, 2 up in Sunday singles. He trailed 2 down with seven holes to play, then won three straight holes and four of the next six to seize control. After dropping the 16th, he made par on 17 and hit his approach on the 18th to 8 feet; Kim missed his birdie attempt to end the match.

What was Koivun's full record at Medinah?

Koivun finished 2.5 points from three matches, winning and tying his two four-ball appearances before closing out the singles win. He did not play in the foursomes sessions. Only Tom Kim, with four points for the Internationals, scored more than Koivun across either roster.

A captain's pick this unproven had never looked more justified.

A captain's pick this unproven had never looked more justified than it did with Koivun's finish. "For it to come this quickly is definitely shocking," Koivun said.

How fast has Koivun risen through the pro ranks?

Koivun turned professional roughly three months before the Presidents Cup and won the 3M Open in just his third start on the PGA Tour. He arrived at Medinah fresh off a T-5 finish at the Biltmore Championship Asheville the week before. Cameron Young and Chris Gotterup, also Presidents Cup rookies, each scored three points in their debuts.

What did Koivun accomplish before turning pro?

As the world's top-ranked amateur last year, Koivun went 3-1-0 in the 50th Walker Cup, winning both of his singles matches. He was also 1 up with one hole to play in his NCAA semifinal match against then-No. 1 amateur Preston Stout when Auburn clinched the win on another court, part of the Tigers' run to their second national championship in three years.
