Sergio de Celis Montalban, a Spanish record holder and 2024 Olympian in the individual 100 free, has committed to Arizona State University's swimming team, joining the Sun Devils in the fall of 2026. At 26 years old, Montalban brings a wealth of experience and talent to the team, having already made his mark on the international stage. With a lifetime best of 48.24 in the long course 100 free, he is a formidable addition to the team, especially in the sprint freestyle events. His converted times suggest he will be a top performer, with his 50 free ranking 7th on the roster last season, and his 100 free ranking just outside the top three. The loss of several top swimmers to graduation this summer makes Montalban's arrival all the more crucial, as he will be a key player in restocking the ranks and contributing to the team's success. His impact on the relays is also significant, as he will be a high-impact addition to the 200, 400, and 800 free relay teams, joining a strong incoming class that includes Kristupas Trepocka, Max Smirnov, and Parker Deshayes, among others. With his talent and dedication, Montalban is poised to make a lasting impact on Arizona State University's swimming program.
