( CNN ) -- Rory McIlroy 's bid to clinch the European Tour money list has been hit by bad weather in Singapore -- and the world 's No . 1 golfer has revealed that his tennis star girlfriend is not enjoying the experience . Caroline Wozniacki traveled to Asia to be by his side after her season ended last weekend at a tournament final in Bulgaria , but the couple -- dubbed `` Wozilroy '' -- has had to put up with rain and early-morning starts . `` Nearly 12 hours at the golf course already today ! @ CaroWozniacki really enjoying her holiday this week ... Not ! ! , '' he wrote on Twitter , where he posted a less than flattering picture of the Dane slumped asleep on a desk . McIlroy , unable to complete his first round on Thursday , came back early to post a one-under-par 70 and was then level after 12 holes when the second round of the $ 6 million event was again halted . `` Now I remember why golf is n't my sport ! Waking up at 5.15 is n't really my thing lol ... # notamorningperson , '' Wozniacki posted on Twitter . McIlroy could add to his PGA Tour money list title by winning in Singapore , where officials face the prospect of cutting the tournament to 54 holes for the second year in a row if the disruptions continue . However , he is battling illness which may mean he has to wait until next week 's Hong Kong Open title defense or the season-ending World Tour Championship in Dubai before he can emulate Luke Donald 's feat last year . `` I 'm struggling a bit and not feeling 100 % , '' the 23-year-old told reporters . `` Maybe it 's a good thing that the humidity is so high because I might be able to sweat it out . '' This time last year McIlroy was suffering with an illness suspected to be Dengue Fever , and he ended up finishing second in the Race To Dubai standings behind Donald . England 's world No . 63 Simon Dyson shared the lead with 631-ranked Chapchai Nirat of Thailand when Friday 's play was finally stopped , with both on six under par . Half the field had not played since Thursday , including veteran American Phil Mickelson and fellow major winner Padraig Harrington -- who were both down the field after the opening round .
