Having attended Colegio San Agustin in Makati, he played American collegiate tennis at Louisiana State University (LSU) on a scholarship and was a member of the team which reached the final of the 1988 NCAA Division I Men's Tennis Championships. In the final against Stanford he won in the singles against Patrick McEnroe, but LSU still lost the finals series 2–5.
A right-handed player, Barrientos won several medals for the Philippines at the Southeast Asian Games, three of them gold medals, including in the men's singles when Manila hosted the event in 1991.

His other singles main draw appearance on the ATP Tour came at the 1991 Queen's Club Championships, then at Taipei the following year, for first round losses to Pat Cash and John Fitzgerald respectively.
Barrientos was a regular member of the Philippines Davis Cup team during his career and featured in a total of 15 ties, for an 18/5 win-loss record in singles and overall record of 26/10. In 1991 he helped the Philippines reach the World Group playoffs.
