His signature event is the 100 butterfly, the event he has raced the most, followed by the 100 freestyle and 200 freestyle. Butterfly is the backbone of the whole record: 65 meets and 120 recorded swims.
His fastest 100 butterfly stands at 58.96, set in long course (50 m) at Centro M-86 (exterior) - MADRID.

The record runs unbroken from 2018 to 2026: 9 consecutive seasons without a single missing year. 2023 is the busiest season on record, with 52 verified individual swims.
