The PGA Championship has become a lot more concentrated at the top of the leaderboard. Four players are currently on the course and tied for the lead at -5, including Americans Matt Kuchar, Zach Johnson, and Nick Watney. Korean Seung Yul Noh is also tied for the lead at -5.
Noh is a 19-year-old professional who became the second youngest winner in European Tour history (to Kiwi Danny Lee) when he won the Malaysian Open earlier this year. He was invited by the PGA of America to participate in the tournament to fill out the field.
US Open 54 hole leader Dustin Johnson is at -4, along with Ernie Els. Bubba Watson and Francesco Molinari will not start their second rounds until 6 and 7 p.m. ET respectively.
