Paul McGinley believes Shane Lowry's Jekyll and Hyde form could help the Offaly man become a Ryder Cup star.

The Dubai Duty Free Irish Open host — who spoke about initially feeling "despondent" when Rory McIlroy ruled out an appearance at Lahinch — admits that Lowry has the same streaky DNA as golf's big-time players.

"Shane's got the DNA of golfer I wish I was," McGinley said of Lowry who has sandwiched four missed cuts between a win and a third-place finish.

"Professional golf is not about being a steady Eddie. And I made a lot of cuts and had a lot of 20ths and a lot of 15ths.

"When I got hot, my confidence level got to eight out of ten. But when Shane gets confident, or Darren Clarke got confident, it's 9.99. They were off the scale with confidence.

"That generally turned itself into a win or a second-place finish. And that's huge cheques, huge world ranking points, huge order of merit points and huge Ryder Cup points. 

"Those are the things that determine the success you have from year to year."

With Ian Poulter added to the Irish Open field alongside Lowry, Louis Oosthuizen, Lee Westwood, Graeme McDowell and Padraig Harrington (with more big names potentially still to come), McGinley's fears about the Irish Open field have dissipated.

Unlike his 2015 Ryder Cup captaincy, where he said "the answer to every request was 'yes'," he's had to work hard to build the field for Lahinch.

"This is different," he said. "I’m on the back foot on a lot of things here.  I’m having to bob and weave and work through it, and initially, I was so despondent thinking, ‘I’ve not got a good feeling here, this is frightening’.

"Then the Rory news was broken, I thought, ‘Oh my God, where are we going to go, how are we going to fix that up?’

"I spoke to Jay Monahan, who runs the PGA Tour,  and he said if you had three or four of the big-name guys and those [lower] tiers coming in, ‘that’s the DNA of a modern golf tournament’ unless you’re running a World Golf event, a major championship or The Players."

Lowry and Harrington did not get to start in the PGA Tour's storm-delayed Zurich Classic of New Orleans, where Seamus Power and David Hearn and Graeme McDowell and Henrik Stenson have also teamed up. Scores
