Rory McIlroy vowed to use controlled aggression as he looked to ignore the distraction of Donald Trump's arrival to win his third WGC title in the Cadillac Championship on Sunday.
Course owner and US presidential hopeful Trump arrived at Doral by helicopter around 30 minutes before the final group of McIlroy and Dustin Johnson teed off, and spoke with both players soon after on the range.
The conversations appeared brief and McIlroy was left to complete his final preparations, the world number three seeking to join Jack Nicklaus and Tiger Woods as the only players since 1945 to win 12 times on the PGA Tour before the age of 27.
McIlroy, who would also join Geoff Ogilvy (three) and Woods (18) as the only players to have won three or more WGC titles, held a three-shot lead over playing partner Johnson and former world number one Adam Scott, who won the Honda Classic last week.
Speaking before his round, the 26-year-old told Sky Sports: " I think going into the final round with the lead, you have to choose your points where you are going to be aggressive.
"The conditions seem a little tougher with the wind up so I am going to have to play aggressively on some holes but still have a controlled plan and just be smart out there.
"The par fives and some of the shorter par fours you need to take advantage of and if I can do that then hopefully I will be okay."
Missing the cut last week prompted McIlroy to successfully switch to a cross-handed putting method he last used in 2008, and he added: " When you have confidence with the putter it feeds the whole way through your game. You don't have to put so much pressure on yourself with the long game.
"I feel every aspect of my game has been really good this week and it's improving each and every week."
Pars on the first two holes were enough for McIlroy to remain three shots ahead of Johnson, with Scott having closed to within two with a birdie on the first before finding water on the third to run up a double bogey.
