2024: Professional debut Del Toro made his professional debut in January 2024 at the
Down Under Classic, finishing in the podium. Four days later he claimed his first
UCI WorldTour stage victory by winning stage 2 of the
2024 Tour Down Under. Although not starting the race as the team's designated leader, UAE Team Emirates gave the young Mexican rider the freedom to race for the stage. Del Toro attacked on the final climb with around 1 km remaining and held off the favourites to take a solo victory. The victory was widely regarded as a major milestone for Mexican cycling, marking the end of a 22-year drought for the country at the WorldTour level of the sport.
2025: Giro breakthrough At the
2025 Giro d'Italia, del Toro began the race in a support role within a UAE Team Emirates-XRG squad led by
Juan Ayuso and
Adam Yates. On stage 9, over the race's gravel roads to Siena, he finished second to
Wout van Aert and moved into the overall lead, becoming the first Mexican rider to wear the maglia rosa. As Ayuso's challenge faded and he later abandoned the race, del Toro emerged as UAE Team Emirates-XRG's main general classification contender. He won stage 17 with a late attack, secured the
young rider classification, and finished second overall. Del Toro became the first North American rider to win the Giro's young rider classification. The loss of his race leadership on the
Colle delle Finestre sparked intense scrutiny regarding the tactics used during the battle between del Toro,
Richard Carapaz, and the eventual winner,
Simon Yates. In 2025, he also enjoyed a successful campaign in the Italian classics, winning
Milano–Torino, the
Giro dell'Emilia, the
Giro del Veneto, and
Gran Piemonte, while also finishing fifth at
Il Lombardia.
2026: First WorldTour stage race wins At the
2026 UAE Tour, UAE Team Emirates-XRG announced del Toro alongside
Adam Yates as one of the team's leaders for the race, marking the first time he had been publicly designated as a team leader for a
UCI WorldTour event. He won stage 1 and later secured the overall title with victory on stage 6, claiming his first
UCI WorldTour general classification win. At the
2026 Tirreno–Adriatico, del Toro won stage 6 to extend his lead before sealing the general classification victory the following day, becoming the first North American rider to win the race. ==Major results==
