Ireland's Shane Lowry is in the mix at the US PGA Championship after an encouraging opening round in the year's first major at Harding Park.
The 2019 Open Champion carded a two-under-par opening round, and is just three shots back from clubhouse leader Jason Day.
Rory McIlroy has also carded a level-par round, recovering three bogeys in a row on the back-nine to land two birdies in the final three holes.
Elsewhere on the course, defending champion Brooks Koepka is just one shot behind the lead while Tiger Woods also impressed to post a two under par round in San Francisco.
"No matter what happened in the past you're going out there in any given week just trying to perform your best," said 33-year-old Lowry yesterday.
"The only thing I can do this week is go out tomorrow and try and shoot the best score I can."
Lowry has struggled since the PGA Tour returned from its hiatus in June, missing the cut at the Charles Schwab Challenge and RBC Heritage, but things turned around last week in Memphis, where he finished sixth at the WGC FedEx St Jude Invitational.
"I've been playing good golf recently, and I've really struggled on the greens. I've really struggled with - I've been on my own trying to figure it out for myself. I hadn't seen my coach Neil since March. Hadn't seen (caddie Bo Martin) since March," said Lowry.
"Bo just kind of said a couple of things on the putting green at the start of the week and I feel it clicked."
