Professional

The Tampa Bay Mutiny selected Vargas in the twelfth round (117th overall) in the 1996 MLS Inaugural Player Draft. He spent two seasons with the Mutiny before the Miami Fusion selected Vargas in the 1997 MLS Expansion Draft. On July 25, 2000, while playing in an Open Cup game in Saginaw, Michigan, Vargas sustained a right ankle sprain that turned out to be a career-ending injury. After three seasons in Miami, the Fusion waived Vargas in November 2000.^[1]

International

In 1991, Vargas was a member of the United States men's national under-17 soccer team at the U-17 World Youth Championship which went 3–0 in the first round. In the second round, the team tied Qatar 1–1 in regulation only to fall 5–4 in penalty kicks.

That same year, he earned his first of four caps with the U.S. national team when he came on at half time for Mike Slivinski in a September 14 win over Jamaica. At the time, Slivinski was the youngest U.S. player to earn a cap and Vargas was only three months older. Vargas did not play again with the senior national team until November 19, 1994, in a loss to Trinidad and Tobago. He then played two more games that year, his last coming on December 11.^[2]

In 1993, Vargas was selected for the U.S. team which qualified for the 1993 U-20 World Cup to be held in Australia. He scored two goal in the CONCACAF qualifying games. At the World Cup, the U.S. went 1-1-1 in group play, qualifying for the second round where it fell to Brazil.

In 1996, U.S. coach Bruce Arena named Vargas to the U.S. soccer team at the 1996 Summer Olympics. Once again, the team went 1-1-1, but this time failed to make the second round.
