A goal from Enric Franquesa and another from Senegalese Mamadou Sylla allowed the Girona to win in Vallecas to the Lightning and getting his ticket to Primera on track with everything in favor for the second leg in Montilivi.
In the first half, Rayo jumped onto the pitch with one more march than his rival and in the first minutes the approaches to the goal of Juan Carlos were happening until in a play down the left wing, badly defended by Girona, Isi Palazón found himself with a ball that sent directly to the bottom of the net.
That initial dominance of the Rayo occurred during practically the entire first half at the rate that the Argentine Oscar Trejo wanted to mark, well supported at the ends by Isi and Álvaro García, who They did not stop destabilizing the defense of Girona.
At 40 minutes, when Girona seemed more touched, the Senegalese Mamadou Sylla won the race against Esteban Saveljich, he turned back and put a ball so that Enric Franquesa, faster than Advíncula, he will score against Luca Zidane.
Before the break, the controversial play arrived. Gerard Gumbau fired a shot from outside the area that hit Nahuel Bustos on the arm and misled Luca Zidane. The goal, initially conceded, was annulled after consultation with Pulido Santana at the VAR.
That scare that Rayo suffered was translated into reality in the first play of the second half, when Arnau won the baseline, put a low ball to the heart of the area and Sylla finished at pleasure.
The goal left Rayo very touched and gave Girona wings, which put the Madrid team in a lot of trouble, especially in quick plays looking for Sylla and, later, the Uruguayan Christian Stuani, who with his entry to the pitch caused the locals to risk little defensively.
With two minutes to go until the regulation time was fulfilled, José Pozo, in his first intervention, found a ball yielded by Leo Ulloa to finish it off on goal, but the referee, after consulting the VAR, he canceled it, when the euphoria had taken possession of the Ray. In the seven minutes of injury, Rayo appealed to the heroic one and went upstairs with everything, but impatience took its toll because the approaches did not bear fruit on any clear scoring occasion.
