Gaitán moved to Mexico for the 2002 Apertura season, signing with Tigres UANL of the Primera División (First Division, now Liga MX) by request of Ricardo Ferretti.
After a remarkable Apertura 2003 season under coach Nery Pumpido, Gaitán and Tigres lost the finals against Pachuca in the Estadio Universitario.

In October 2007, Gaitán, citing personal reasons, asked for a three-month license to be absent from the team until the end of the season.

Gaitán did not achieve the League championship with Tigres, still, he is considered by the media and audience as an icon of the team, next to players such as Tomás Boy, Gerónimo Barbadillo, Osvaldo Batocletti, Claudio Núñez, Lucas Lobos and André-Pierre Gignac.
