Jackson Suber snatches RBC Canadian Open lead as Sunday storm looms

The American signed for a four under 66 around Shinnecock Hills, aenough to take hiom to13 under for the tournament, one shot ahead of Bud Cauley, who is in solo second, and both are chasing their maiden PGA Tour title.

Suber got up-and-down for a birdie on the par five 18th to sneak to the top of the leaderboard. However, the job is far from done, as rain and wind are predicted to dominate proceedings on a soaking Sunday.

"I've just hit good drives there and I feel like I've been in a good spot and iron play seems to be my strength," the 26-year-old told AP.

"The conditions are going to be really rough and no matter my start, if I start with an eagle or a bogey, it's going to be a tough day and it's not going to be won on the first probably nine to 15 holes. So just staying patient."

Hot on Suber and Cauley's heels are Wyndham Clark and Tommy Fleetwood, along with Brice Garnett and Jesper Svensson and on 11 under. Clark carded a round of the day 63 to put himself well in contention.

A group win Billy Horschel and Sam Burns are on ten under, while the European quartet of Matt Fitzpatrick, Shane Lowry, Viktor Hovland and Robert MacIntyre lurk on nine under.

Five-time major winner Brooks Koepka had dealt with a strange feeling in his left arm that made it difficult for him to grip the club for most of the day, leading to a two-over 72.

"I'm struggling to grip the club with my ring finger and pinkie finger, so can't grip it," he said.

"My fingers would come loose; it was kind of numb. I don't know what the deal was, but hopefully we'll figure it out."
