Orreal qualified for the inaugural Grand Slam of Darts for reaching the final of the PDC Australian Open where he lost to Glen Power.
The result meant that Power had initially qualified for the event but was forced to withdraw due to visa problems and Orreal replaced him.
He reached the last 16 of the 2007 Grand Slam of Darts, defeating Niels de Ruiter and Phill Nixon to finish second in his group before losing to Jelle Klaasen 10–9.
He then reached the semi-final of the Australian Open Players Championship, achieving wins against Mellisa Sinnott, Barry Jouannet, Denis Ovens and Warren French before losing to Paul Nicholson.
He then suffered a first round exit from the Oceanic Masters, a tournament where the winner wins a place in the PDC World Darts Championship.
