He achieved FINA B-standards of 1:05.61 (100 m breaststroke) and 2:20.00 (200 m breaststroke) from the 2000 Janet Evans Invitational in USC Los Angeles, California, United States. In the 100 m breaststroke, held on the first day of the games, Madrigal established a new Costa Rican record of 1:05.14 to lead the second heat, but ended up overall in forty-eighth place. Three days later, in the 200 m breaststroke, Madrigal placed forty-third on the morning prelims, swimming in heat three.
