In 2006, Martínez dropped down to the second level to play for Club Atlético Tigre, but won promotion in his first season. The Apertura 2007 was the club's first year in the top flight since 1980, and the player appeared in nearly all of the team's matches helping to a final second-place finish, the highest in their history.
Martínez was subsequently loaned for one season to CD Tenerife, which had returned to La Liga after seven years.[8] In an irregular campaign, where he alternated starts with the bench, he scored four of his five league goals in the last seven matches – which granted the team six points, after wins against Gijón[9] and Racing de Santander[10]– but the Canary Islands side were finally relegated.
Martínez returned to Argentina for 2010–11, re-joining Tigre on a one-year loan.[11]
Personal life
Martínez's younger brother, Nicolás, was also a footballer.[12]
