* Senior club appearances and goals counted for the domestic league only.
He is also a member of the Guatemala national football team.
Nicknamed "Titi Man", Ávila made his mark in the 2007 Clausura season, considered a breakthrough season for the winger, scoring 6 goals including a hat-trick against Deportivo Petapa. His form and quick rise for both his club and the national team were the main reasons behind his move to Guatemala's biggest club, Municipal, for the 2007-08 season. On his debut for Municipal in the 2007 Apertura against his former club, CD Suchitepéquez, he scored the winning goal, a spectacular one-time volley off a corner from Freddy García.
In 2009 he had a short stint at Chinese side Shaanxi Chanba, being the first Guatemalan player ever to play for a club in Asia. He then returned to Municipal.
Ávila made his international debut as a late substitute in a match against the United States in a pre-World Cup friendly in February 2006. He scored his first goal for the Guatemalan senior side in a friendly match against Honduras later that year. On 17 October 2007, in a game against the Mexico national team, he came of age at the international level, scoring a brace (first the equalizer and then the winner) and setting up an earlier goal. This superb performance helped Guatemala beat Mexico for the first time in almost 7 years. As of January 2010, he has collected 24 caps, scoring 3 goals and he has so far represented Guatemala in 2 FIFA World Cup qualification matches. He also played at the 2007 CONCACAF Gold Cup.
In 2007 and 2008 he was part of Guatemala's under-23 team scoring the winning goal against Haiti, and although the Guatemala National Team started the tournament off strong, they slowly began to lose momentum and eventually fell short of qualifying to the 2008 Olympic tournament.
