After finishing his third round with a three-stroke lead early Sunday, Rory McIlroy's advantage was down to one stroke when his final round was halted due to weather conditions at the K Club.
Part of Sunday's delay was due to a hailstorm, which was oddly enjoyed by Scotland's Russell Knox - though, that may be more to do with the fact he now sits just one shot behind McIlroy.
Both players were through eight holes of their final rounds at the time of the delay.
