Day one digest: 2020 US PGA Championship

Three former champions were fighting at the top end of the US PGA Championship leaderboard on the opening day of the first Major of the year.

Here is everything you need to know from day one at TPC Harding Park.

It was Jason's Day until Todd's late charge

A flawless first round 65 saw 2015 champion Jason Day take the early clubhouse lead on Thursday. And with the wind picking up later in the day it was hard to envisage any of the afternoon starters catching him. But Brendon Todd did just that thanks to a late burst of birdies and a great par save.

Lewis' lovely long putt

Tom Lewis caught fire over the weekend at last week's WGC-FedEx St Jude Invitational, equalling the course record at TPC Southwind with a fine 61 on Saturday before Sunday's 66 saw him grab a share of second place. He carried that form into this week's tournament, opening up with a bogey free 67 that contained one of the best putts of the day. Having carded nothing but pars since the sixth hole, Lewis looked unlikely to change that when his tee shot on the short 17th landed in the fringe but he confidently holed his huge putt from around 65 feet to bag a birdie.

Koepka makes ominous start to double defence

To say Brooks Koepka likes this event is a bit of an understatement. He is the two time defending champion, having followed up success at Bellerive Country Club by winning at Bethpage State Park BK Course in May last year. He warmed up for his shot at a historic 'three-peat' with a runner-up finish at TPC Southwind last time out before warning his competitors ahead of this week's event that he is in great shape. He wasn't kidding. He made six birdies and just two bogeys to sit one shot back.

Kaymer takes inspiration from 2014 U.S. Open win

After carding an eagle, four birdies and two bogeys in a battling first round performance at TPC Harding Park, two time Major Champion Martin Kaymer revealed he had watched a replay of the back nine of the final round of his U.S. Open win at Pinehurst on Wednesday evening to give himself inspiration. It certainly worked as he put the fact that he's only made one competitive start since March to the back of his mind and shot a 66 which leaves him one shot off the lead.

Bryson breaks his driver

The look of shock on Bryson DeChambeau's face was there for all to see when he bent down to pick up his tee at the seventh and the head fell off his driver. He was allowed to replace the shattered shaft and went on to sign for a 68 that included a brilliant birdie at the 13th which came courtesy of a perfect approach shot to two feet.
