Cink carded a four-under-par 68 to lie two shots off the lead after a weather-affected opening day and is a top-priced 7/1 with bet365.

Jonathan Kaye shares the clubhouse lead with Ryan Palmer, Jonathan Byrd, Parker McLachlin and Kenny Perry on six-under as torrential rain stopped play for half-an-hour in the afternoon and caused a large back-up that prevented 34 players from finishing their rounds.

Perry is the second favourite at 9/1 with Stan James, Byrd is 11/1 with the same firm and it's then 14/1 bar.

That brings in defending champion Zach Johnson who battled through the inclement conditions in the afternoon to card a three-under 69 with five birdies and a bogey.
