Graeme McDowell will take a one-stroke lead into the final round of the Corales Puntacana Resort and Club Championship after another impressive display in the Dominican Republic.
Former US Open champion McDowell, three shots behind overnight, signed for a second successive 64 – which could have been lower but for two bogeys on the front nine before recovering with four birdies to finish at 15 under par.
The Northern Irishman is looking to win on the PGA Tour for the first time since the OHL Classic at Mayakoba in November 2015.
American Chris Stroud also matched McDowell's eight-under round, with his 64 including an eagle to put him one clear of Korea's Sungjae Im, who shot a 69, and Aaron Baddeley after the Australian carded a four-under round.
Canadian Mackenzie Hughes was a big mover on Saturday following his 66 to sit at 11 under in a tie for fifth place with Sepp Straka, Kelly Kraft and Paul Dunne, who shot a 70.
Séamus Power carded a level-par 72 and is four under for the championship.
