US PGA Championship - Day one digest

Everything you need to know from day one of the second Major Championship of the season.

Xander Schauffele made history, Rory McIlroy was thankful for a "big swing", Robert MacIntyre was feeling at home and Scottie Scheffler was being Scottie Scheffler in the first round of the US PGA Championship.

Here is everything you need to know from Thursday at Valhalla Golf Club.

Schauffele dominates day one

Schauffele became the first man to card two rounds of 62 in Major Championships as he opened up a three-shot lead after day one. Just 11 months after matching the record for the lowest round in a Major at the U.S. Open, he carded the lowest round in US PGA Championship history to get to nine under at Valhalla Golf Club. Tony Finau, Mark Hubbard and Sahith Theegala were the nearest challengers, a shot clear of Belgian Thomas Detry, Scotland's Robert MacIntyre, Northern Irishman Rory McIlroy, South Korean Tom Kim and Americans Tom Hoge, Maverick McNealy and Collin Morikawa. “It feels great,” Schauffele said. “It’s just day one but if someone had said I was going to shoot nine under I would certainly have taken it."

Rory in the swing

McIlroy arrived in Louisville as one of the favourites after winning his last two starts but the World Number Two’s round was in danger of falling apart when he followed two early birdies with a bogey on the 17th and a tee-shot into the water on the 18th. However, after taking a penalty drop and pitching out on to the fairway, McIlroy hit a superb approach to seven feet to save par and then hit the pin with his second shot on the next to set up a short-range birdie. “That was huge,” McIlroy admitted. “I could have easily bogeyed 18 and been back to even par, and then that ball on one could have hit the flagstick and went anywhere. I could have made bogey from that. “Potentially being one over par through 10, I’m two under so it’s a three-shot difference. It’s a big swing.”

Bob feeling right at home

MacIntyre hailed the impact of a trip home to his beloved Scotland after finding his form with an opening 66. After one top ten and five missed cuts in ten PGA TOUR events up until the end of March, he headed home to Oban and since his return to his base in Orlando, he has secured another top ten at the Zurich Classic of New Orleans alongside Thomas Detry and finished 13th at last week's Myrtle Beach Classic. A bogey-free start at Valhalla has continued that improvement and MacIntyre is in no doubt of the reason behind his upturn in form. "My game hadn't been as good but there's been good form coming into this and I'm a happy person just now," he said. "I managed to get home for three weeks and spend time with the people closest to me and that's when I play my best golf, when I'm in a happy mindframe. I got three weeks at home there and hardly touched the golf clubs, done some stupid stuff and just enjoyed myself.”

Scheffler off to a flier

The World Number One arrived this week after just becoming a father for the first time so with the inevitable sleepless nights and big lifestyle changes, he could have been forgiven for being off his game. But this is Scottie Scheffler - he hit a perfect drive down the first and then holed a nine iron from 167 yards with one bounce for an opening eagle. He's an animal.

A Daly occurrence

We don't see a lot of the Wild Thing anymore but it's still never dull when we do.
