Here comes Si Woo Kim.

The 21-year-old Kim is charging up the leaderboard in the second round of the U.S. Open. He birdied three straight holes to move into second at 6 under, one shot back of co-leaders Rickie Fowler and Xander Schauffele.

Kim won The Players Championship in May for his second PGA Tour title.

Bill Haas also is off to a nice start, with three birdies and no bogeys through his first eight holes. He is 3 under for the tournament.
