On 5 April 2015, after being already a regular with the B's and being called up to the main squad by manager Marcelino García Toral,[5] Pedraza made his professional – and La Liga – debut, replacing Jonathan dos Santos in the 72nd minute of a 0–0 draw at Valencia CF.[6] On 28 July 2016, he was loaned to Segunda División side CD Lugo for one year,[7] scoring his first professional goal on 21 August by netting the first in a 2–2 away draw with Gimnàstic de Tarragona.[8] He ended the season with six successful strikes and eight assists, helping to a final ninth position.[9][10]
On 31 January 2017, Pedraza joined Leeds United on loan until the end of the campaign,[11] with Villarreal paying Lugo £300,000 in order to cancel his contract with them – the deal with the English side included an option to buy for £8.5 million in May, provided they won promotion from the EFL Championship.[12] After featuring from the bench in his debut, a 2–1 loss at Huddersfield Town,[13] he scored his first goal on 3 March in a 3–1 away win over Birmingham City;[14] as the team could only rank seventh, he returned to the Estadio de la Cerámica.[15]
On 5 July 2017, still owned by Villarreal, Pedraza signed with Deportivo Alavés for one year with a buyout clause.[16] He scored his first goal in the Spanish top flight on 21 January 2018, putting the hosts ahead 2–0 in an eventual 2–2 home draw against CD Leganés.[17]
Upon returning from loan, Pedraza was regularly deployed as a left-back by manager Javier Calleja, and was definitely included in Villarreal's first team.[18] On 4 November 2018, he scored his first goal for the club to earn a 1–1 home draw against Levante UD in a local derby.[19] The following 14 February, he scored the only goal after three minutes in a win at Sporting CP in the last 32 of the UEFA Europa League.[20]
On 16 July 2019, Pedraza moved to Real Betis on a one-year loan, with an option to make the deal permanent at the end of the season.[21] From December to March, he suffered from muscular and Achilles tendon injuries.[22] His only goal for the Seville-based side came on 8 July 2020 in a 3–0 home win over CA Osasuna that ensured another season in the top flight;[23] on 24 September he extended his contract until 2025, after having his role in the team guaranteed by new manager Unai Emery.[24]
Pedraza played mainly as a left winger, but could also operate on the opposite flank cutting inside or as a forward. His style of play was compared to Gareth Bale due to his speed running with the ball, as well as his strength and ability to take on defenders.[31]
Spanish football expert Guillem Balagué described Pedraza upon signing for Leeds: "It’s one of the most exciting transfers of the winter... He’s a 20-year-old, he mirrors himself on Denis Cheryshev – a winger who goes forward and works really hard. And he’s a goalscorer".[32]
