Play was suspended at 1:45 p.m. following nearly two hours of steady rain that saturated the course and caused ponding on the greens.

Barlow’s clinching putt on 18th highlights first round. In first-round match play, the most dramatic moment of the day came on the 18th hole of the match between Andrew Yun, an incoming freshman at Stanford, and Zach Barlow, a senior at Illinois.

With Barlow 1 up, Yun needed to win the 18th to extend the match. When his third shot on the par 5, 570-yard hole ended up over the green 40 feet from the flagstick, Barlow – whose third shot was almost the same distance from the hole but on the green – appeared ready to close the match with two putts.

Yun changed Barlow’s odds, though, holing his 40-foot chip shot for birdie.

Facing the prospect of extra holes, Barlow stepped up to his putt and stroked it in the center of the cup to match Yun’s birdie, halve the hole and move into the quarterfinals.
