The Estrella Damm Andalucía Masters got under way on Thursday at the Valderrama club near Sotogrande.
All eyes were on world-number-one-ranked player Jon Rahm, who had previously told the press that winning at Valderrama would be "very special". This was where the 26-year-old Basque player's relationship with golf started, he said, as some friends of his parents came to watch the Ryder Cup in 1997.
"Valderrama is a very difficult course, which accentuates any weakness you might have," Rahm had admitted prior to the tournament.
This proved to be true on the first day when Rahm had four bogeys and a double bogey on his front nine holes and another bogey on his back nine, finishing with a disappointing card of 78 strokes, seven over par and one of his worst performances ever as a professional.
Meanwhile fellow Spaniard, Rafael Cabrera Bello (ranked 17), shone, finishing day one in second place (-4) behind Frenchman Julien Guerrier (-3).
Now Rahm has a difficult day ahead this Friday as he attempts to make the cut in this edition of the Andalucía Masters.
"The blame is one hundred per cent mine," he said.
