Graeme McDowell remains on course for a $422,500 pay day after he combined with Argentina’s Emiliano Grillo to grab part of three-way tie for the lead heading into the final round of the 54-hole QBE Shootout in Florida.

The pair carded a six-under 66 in the scotch foursomes in Saturday’s second round at Tiburón Golf Club in Naples to share top spot with Gary Woodland and Charley Hoffman (64) and Patton Kirrire and left-hander Brian Harman (66) on 19-under par.

The leaders are one stroke clear of Kevin Na and Bryson DeChambeau (67) with Luke List and Charles Howell III one stroke further back on 17-under.

McDowell and Grillo birdied the second, sixth and eighth before making five birdies in a row from the 10th in a round that also featured bogeys at the par-four third and par-four 15th.

McDowell was runner-up with Darren Clarke in 2010 and Shane Lowry last year.

Meanwhile, Paul McGinley was six shots adrift of Clark Dennis heading into the final round of the MCB Tour Championship - Mauritius.

He finished with three birdies to card a second round 68 that left him fifth on nine-under par as Dennis added a 66 to his opening 63 to lead by three strokes from Swede Magnus P Atlevi on 15-under.

Brendan McGovern’s season looks to be over after a 73 left him on five-over.

He’s 37th in the Order of Merit and only the top 29 and three invitations will make the final event of the 2018 Staysure Tour season next week, the MCB Tour Championship – Seychelles.

Louis Oosthuizen produced a gutsy 67 to take a three-shot lead into the final round of the South African Open hosted by the City of Johannesburg.

The 36 year old is a Major Champion with four of his other seven European Tour wins coming in South Africa but his home Open is still missing from his trophy cabinet.

He entered day three at Randpark Golf Club two shots behind countryman and fellow Major winner Charl Schwartzel but produced a masterclass of mid-range putting and bunker play to move to 14 under and lead the way.

Schwartzel was in the group in second alongside England's Matt Wallace and Zambian Madalitso Muthiya, with a group of eight players then six shots off the lead.
