Darre Clarke is the toast of bookies and his in-play backers tonight according to Ladbrokes.
Clarke was a widely unfancied 150/1 chance pre-tournament and was a fantastic result for the layers who are heralding one of the best Opens in recent years thanks to increased turnover and favourable places.
In-play results proved less profitable thanks to Clarke's army of fans who supported him over the weekend with a £75,000 bet at 5/2 the lowlight of in-play business for the firm. Clarke was also popular in the top Irish player market at 20/1.
"Clarke's backers really fancied him in the conditions and didn't depart him throughout. In weather to suit we expect McIlroy to make amends in the USPGA."
