Defending champion Koepka in ominous form at US PGA Championship as Lowry and Woods endure tough rounds
Graeme McDowell made a solid start at the US PGA Championship but Shane Lowry faces an uphill battle to make the cut after a tough day at Bethpage.
Defending champion Brooks Koepka looks the man to beat once again after tying the course record with a very impressive seven-under-par round of 63, which sees him four shots clear as things stand.
Koepka, who has also won back-to-back US Open titles as well as last year's US PGA Championship triumph, shot a bogey-free round, which also featured six birdies.
His playing partner Tiger Woods was a long way off the form that saw him win the Masters last month, with the 43-year-old slumping to a two-over-par round of 72. It was a topsy-turvy round for Woods, who holed a long eagle putt at the fourth but also double-bogeyed the 10th and 17th.
It was a mixed day for the Irish players who teed off early on. Graeme McDowell can be happy with his even par 70, which saw him card three birdies and three bogeys.
However, Shane Lowry faces a big task to make the cut after a five-over-par round of 75.
Lowry bogeyed seven holes during his round, and only made two birdies.
Rory McIlroy and Padraig Harrington are still to play their first rounds.
