Arnold Palmer Invitational Round 1: Daniel Berger Fires a Bogey-Free 63 to Lead by Three

Bay Hill was supposed to be the week's bully. On Thursday, Daniel Berger flipped the script and pushed it around.

Berger went out early, shot a bogey-free 9-under 63 and finished the opening round of the 2026 Arnold Palmer Invitational presented by Mastercard with a three-shot lead. Collin Morikawa and Ludvig Åberg share second at 6 under after matching 66s. Cameron Young and Jhonattan Vegas are tied for fourth at 5 under, and Ryan Fox, Xander Schauffele and Adam Scott sit at 4 under. Only 32 players in the 72-man Signature Event field broke par.

Nine Birdies, Zero Drama

The scorecard was almost boring in its precision. Nine birdies, nine pars, and every birdie putt came from inside 12 feet, according to Golf Channel. That is not a hot putter bailing out a loose ball striker. That is a player putting the ball exactly where he wanted it, over and over, on greens that were already firm and fast in the morning.

The 63 is the lowest round at Bay Hill since Scott shot 62 back in 2014, and per the AP it was nearly nine shots better than the field average. For context, the next best score of the day was three shots worse.

The story behind the number makes it even better. Berger has four PGA TOUR wins, but the last one came at the 2021 AT&T Pebble Beach Pro-Am. He broke his right ring finger at the BMW Championship last summer and spent roughly four months away from competition. He told reporters he has been playing well without much to show for it. Thursday was something to show for it.

He also knows what is coming. "It has that U.S. Open kind of feel to it," Berger said, per the AP. "I think the course is just going to get tougher as the week goes on."

Morikawa Closes Like a Freight Train

Morikawa spent most of his morning in the middle of the pack, then finished eagle, birdie, birdie on 16, 17 and 18 to post 66. Golf Channel noted that ties his best three-hole stretch on TOUR. He ranked second only to Berger in iron play on the day and also poured in putts from 40, 39 and 29 feet, per CBS Sports.

This place carries baggage for him. Morikawa held the 54-hole lead here a year ago and could not convert it on the back nine. Starting the 2026 edition three back with a hot finish in his pocket is a very different emotional starting point.

Åberg Wins the Afternoon

The late wave got the worst of it. The wind gusted and swirled, the greens yellowed as the day went on, and CBS Sports reported that the afternoon starters played nearly two strokes harder than the morning group. Åberg posted the best score of that half of the draw anyway.

He went out with four birdies on the front nine, then opened the back with consecutive bogeys, the kind of stumble that turns a good Bay Hill round into an ordinary one. Instead, he answered on the par-5 12th with a 5-iron to 25 feet and rolled in the eagle putt. The Swede shrugged off the bogeys afterward, noting that they come with the territory at Bay Hill.

Young had seven birdies in his 67, and Vegas matched it. Scott, a Bay Hill veteran, summed up the setup better than anyone. "It's a little bit like a mini U.S. Open playing Bay Hill," Scott said, per the AP.

Scheffler Steadies, Rory Bites the Rocks

Scottie Scheffler opened with a 2-under 70, his first under-par opening round since his first start of the season, which he won. He hit just 10 greens and putted about average, but the new driver in his bag gained him strokes, and he dropped a 32-footer for birdie on 13. "Anything under par on this golf course is a decent score," Scheffler said. He sits seven back alongside defending champion Russell Henley, who also shot 70.

Rory McIlroy had a tougher afternoon. He got to 3 under before his approach at the 13th caught the rocks and bounced into the water, leading to a double bogey. A bogey at the last left him at even-par 72, nine behind.

Rough Starts

Nobody's day swung harder than Nico Echavarria's. The recent Cognizant Classic winner went out in 30, then came home in 42, including a triple bogey at the 12th, to finish at even par. That is a 12-shot swing between nines, and a perfect advertisement for what this course does to anyone who blinks.

Justin Thomas, back on TOUR after back surgery, shot 79 in his first round of the season. He made double bogey at 11 after missing a 3-footer and another at 16 when his wedge from 81 yards found the creek. Thomas said the rust was about what he expected. He will need something special on Friday to see the weekend.

The Friday Stakes

Signature Events still have a 36-hole cut, and Friday will sort out who is playing for the $20 million purse over the weekend and who is packing for TPC Sawgrass. Up top, the question is simple: can anyone keep pace with a 63 on a golf course its own leader expects to get harder by the hour? Berger has a three-shot cushion, a clean card and a golf course that is only getting firmer. Morikawa and Åberg have the form to close the gap. Friday's job for the chasers is not to catch him. It is to not lose any more ground.
