World number one Jon Rahm endured a dreadful opening day at the Andalucia Masters he carded a seven-over-par 78, but Rafa Cabrera Bello looked sharp again after winning the Open de Espana.
Rahm failed to get a single birdie during what was his worst ever round on the European Tour, and his worst in any competition since the 2018 Open Championship.
But the home crowd's mood was at least soothed by the form of Cabrera Bello, who was fresh from success in Madrid last weekend, coming through a play-off with Adri Arnaus to seal a first European Tour title since 2017.
While Arnaus had something of a nightmare on Thursday as he carded a six-over 77, Cabrera Bello more or less picked up where he left off as he went around in 68, leaving him one behind leader Julien Guerrier.
The Frenchman – who started on the 10th – will be frustrated not to have taken a healthier lead into Friday, however, with two bogeys on his front nine meaning he had to work doubly hard for his one-shot advantage.
Guerrier's countryman Romain Langasque was the only other individual to do better than one-under for the round, highlighting the brutality of the Real Club Valderrama when conditions are windy.
The 26-year-old was helped by an eagle on the par-five fourth hole, though he followed that with successive bogeys.
Six others find themselves tied for fourth on one under par, but much of the attention will be on Rahm's response.
After starting on the 10th, he reached the turn at six-over. While he only dropped one more shot on his back nine, the U.S. Open champion will need to produce something special if he is to avoid the cut.
