PGA Championship 2023 LIVE stream: Leaderboard and latest updates as Bryson DeChambeau surges into lead and Rory McIlroy battles hard

Adam Scott leaks left with his drive at the 9th and can’t recover enough to save par. It’s a bogey and the veteran Aussie goes back to -2.

Patrick Cantlay has a lot of work left for his par and could be dropping to +1 but there’s better news for Justin Rose who bounces back form that clumsy double bogey with a birdie. Back into the red numbers at -1

Here’s how the leaderboard currently looks as the afternoon starters continue their rounds.

• -4: DeChambeau (F)
• -3: Scheffler (F), Conners (F), Scott
• -2: Hovland (F), Bradley (F), Fox (F), Straka, Pieters
• -1: Suh (F), Davis, Buckley, Larrazabal, Burns, D Johnson, Wise, Horschel, Cole
• Others: McIlroy (+1), Mickelson (+1), Morikawa (+1), Thomas (+2), Koepka (+2), Rahm (+6)

Ooof! A double-bogey 5 for Justin Rose at the 5th drops him from -2 back to evens. All that good early work undone in one fell swoop.

Dustin Johnson getting into the red numbers with a birdie at the 7th. Here’s how he managed it

Adam Scott is on a charge now. He has birdied the 8th to move to -3 and is just one stroke behind DeChambeau. He’s driving the ball an absolute mile today, regularly belting the ball 330 yards-plus.

Sepp Straka dropped a shot but he’s still going along well at -2, while Adam Scott found a second birdie to join him on that score.

Phil Mickelson then watches a shot slip away on the 6th to fall to +1, Patrick Cantlay make a sixth straight par to start his round, Dustin Johnson is also at evens through six but Xander Schauffele is flailing at +4.

Good work by Justin Rose early on in his round. This is a Donald Ross-designed course and Rose has won at one of those before. He’s showing his liking for the style by birdieing holes 1 and 3 to immediately jump to two-under. A couple of nice putts to get him there

On a course which has drawn comparisons to Winged Foot, the venue for his US Open triumph in 2020, a slimmed-down DeChambeau still possessed enough power to post six birdies and two bogeys in an opening 66.

That gave DeChambeau a one-shot lead over world No 2 Scottie Scheffler and Corey Conners, with Viktor Hovland, Ryan Fox and Keegan Bradley on two under par.

McIlroy fought back from three over par after nine holes to return a 71, while Masters champion and world No 1 Jon Rahm surprisingly slumped to a six-over-par 76.

Sepp Straka flying early on

Solid enough start from Phil Mickelson, who pars each of the first three holes. Playing partner Patrick Cantlay – another who was attracting plenty of betting money in the build-up to this major – has done similar, while the third in that group Rickie Fowler has a couple of early bogeys and is at +2.
