Rory McIlroy grouped with Jason Day and Phil Mickelson at Baltusrol

Rory McIlroy will be playing with world number one Jason Day and Phil Mickelson in the opening two rounds of the US PGA Championship in the pick of the groups at the year’s final Major championship.

The heavyweight trio get their campaign under way from the 10th hole at 1.30pm Irish time on Thursday, before starting their second round at 6.45pm on Friday.

Shane Lowry, who has struggled for form since his second place finish in the US Open, will be playing with America’s Jim Furyk and Italy’s Frencesco Molinari. The Offaly man tees it up at 6.15pm on Thursday and 1.00pm on Friday.

Elsewhere the year’s three first-time Major winners - Danny Willett, Dustin Johnson and Henrik Stenson - are all playing together at Baltsurol, while Sergio garcia, Jordan Spieth and Bubba Watson make up another intriguing three-ball.

Meanwhile 2008 winner Padraig Harrington has been grouped with fellow veterans Vijay Singh and John Daly.

The weather had a key role in the British Open and the elements are likely to be at play again in New Jersey this week.

Monday’s practice session was suspended in the afternoon due to storms, with the PGA of America advising those at Baltusrol to seek shelter.

More storms are forecast for Friday and across the weekend, and the softening of the course could see some low scoring.

There are also concerns about the heat, with PGA officials advising spectators to bring their own bottles of water to the course on Monday before the rain arrived in the afternoon.
