Alfonso Pastor Vacas (born 4 October 2000) is a Spanish professional footballer who plays as a goalkeeper for Rio Ave.
Born in Bujalance, Seville, Andalusia, Pastor joined Sevilla FC's youth setup in 2013, after representing Séneca CF and AD FB de Bujalance. On 1 September 2018, while still a youth, he renewed his contract until 2021.
Pastor made his senior debut with the reserves on 30 March 2019, starting in a 1–0 Segunda División B home win against UD Almería B. Definitely promoted to the B-side for the 2019–20 campaign, he was mainly a first-choice as the season was curtailed due to the COVID-19 pandemic.
On 3 December 2020, as starter Bono tested positive to COVID-19 and immediate backup Tomáš Vaclík suffered an injury in the warm-up, Pastor made his first team debut by playing the full 90 minutes of a 0–4 home loss against Chelsea.
Pastor represented Spain at under-17 level in the 2017 FIFA U-17 World Cup, acting as a backup to Álvaro Fernández as his side finished second in the tournament.
