J.B. Holmes had a turbulent round, but thanks to an ace and a back-nine birdie run he remains comfortably ahead at the WGC-Cadillac Championship. Here's how things look heading into the final round at Trump National Doral, where Holmes leads by five shots:
Leaderboard: J.B. Holmes (-11), Dustin Johnson (-6), Bubba Watson (-6), Ryan Moore (-5), Henrik Stenson (-4), Bill Haas (-4), Louis Oosthuizen (-4)
What it means: Holmes began with a two-shot lead and was briefly caught by Moore before pulling ahead once again with his ace on No. 4. He appeared ready to fall back to the pack again until he reeled off four straight birdies on Nos. 14-17, reinstating his cushion as he looks to win his first WGC title.
Round of the day: Haas began the day 12 shots off the lead, but he made a big move with a 7-under 65 in the third round. A winner earlier this season at the Humana Challenge, Haas made eight birdies against just one bogey, including four birdies on the back nine, and at 4 under he will begin the final round inside the top five.
Best of the rest: Oosthuizen shot a 5-under 67 in the third round, an effort that was highlighted by three birdies in a row on Nos. 6-8 and an eagle on No. 16 after holing a shot from the greenside bunker. At 4 under, the South African is alongside Haas in a tie for seventh.
Biggest disappointment: Adam Scott began the day in third place, but he spent much of the afternoon on the beach. Scott found nine different bunkers, and after a closing double bogey he carded a 3-over 75 that dropped him to 3 under, eight shots behind Holmes.
Main storyline heading into Sunday: Holmes has shown moments of weakness since his opening-round 62, but each time he has found a way to steady the ship. With the distance to overpower the Blue Monster, Holmes appears in great position to go wire-to-wire and notch the biggest win of his career.
Shot of the day: Holmes and Johnson matched aces on No. 4 just 24 minutes apart, each holing a 7-iron from 207 yards. It was the first time that two players made holes-in-one on the same hole at a PGA Tour event since The Barclays in 2013 at Liberty National.
