Canada's Taylor Pendrith will take a three-shot lead into the final day of the Butterfield Bermuda Championship, with Graeme McDowell some eight shots back.
Building on an impressive score of 61 on day two of the tournament, Pendrith carded a third-round 65 to leave himself 17-under-par going into Sunday's finale at Port Royal.
The 30-year-old recovered from a bogey on the fifth hole to produce seven birdies after tee times were moved forward due to a bad weather forecast.
New Zealander Danny Lee and Australia's Lucas Herbert sit second and third on 14 under and 13 under respectively, having each matched Pendrith's round on Saturday.
Americans Patrick Rodgers and Vincent Whaley are tied for fourth spot, five strokes off the pace.
A consecutive round of 67 saw Graeme McDowell move to nine-under, highlighted by four birdies on the front nine. He is among a number of players sharing tenth spot.
Séamus Power stands at six-under after another 70 on the Port Royal course. The Waterford player's mixed day ending with a bogey on the last.
