2000 to 2006

Prodon's transition to the pro tour was a rocky one. While he first entered the top-300 in late 2000 as a 19-year-old, he spent most of 2001 in the 300's before getting back down into the 230's late in 2002.

Despite recording his first (and only) tour level match win against Ruben Ramirez Hidalgo at Casablanca in 2003, his ranking faded again to the 300's in 2003 and 2004 before improving to the 230's again in late 2004 and early 2005, but an injury in February kept him out for 7 months. Another injury in April 2006 kept him off the court the rest of the year. So he spent most of 2005 and 2006 ranked outside the top-500.

2007: A breakthrough year

Prodon returned to the tour in mid-February 2007, ranked #683, and won Italy F1 in his first tournament back from a 10-month layoff. His ranking continued to slip, despite some Futures success, and by the time he got to Scotland for a Futures tournament in May, he was #721.

But he then went on a tear on the Futures circuit, winning 4 of 7 titles and finishing as the runner-up in the other three while touring Scotland, Algeria, Poland, Belarus, and France, compiling a 32–3 match record during that stretch, to improve his ranking to #290 by mid-July.

He followed that up with a Challenger championship in Finland, beating #116 Raemon Sluiter and #100 Peter Luczak to reach a career-high ranking of #226. In August, he made two straight Challenger finals in Italy and Germany to break into the top-200 for the first time and reach #165, beating #250 Davide Sanguinetti, #117 Boris Pašanski, and #136 Bohdan Ulihrach while losing to #116 Jiří Vaněk and #289 Ivo Minář.

The rest of his year was a bust, going just 2–7 in Challengers, with a win over #657 Martin Verkerk and 2 straight losses to #224 Thomaz Bellucci, as well as losses to No. 90 Luczak and #113 Fabio Fognini to end the year ranked at career-high of #158 at the age of 26.

2008

Prodon continued to be injury-free and making some progress in early 2008. He started the year winning a Challenger in Miami, beating wild card Jan-Michael Gambill along the way. Then he tried and failed to qualify into 3 consecutive ATP stops in Brazil, Argentina and Mexico, losing to No. 60 Óscar Hernández, No. 95 Nicolás Lapentti, and #157 Daniel Gimeno-Traver. He struggle in his return to Challengers in March and April, winning just 1 of 4 matches while losing to #125 Flavio Cipolla and twice to #165 Christophe Rochus. But he regained his form again, reaching two Challenger finals and a semifinal in April and May, beating #127 Iván Navarro Pastor while losing to #107 Eduardo Schwank, #130 Alberto Martín, #199 Younes El Aynaoui on the comeback trail, and #119 Daniel Gimeno-Traver again. That got his ranking to a career-high of #115.

In May, Prodon was given a Wild Card entry into the 2008 French Open.
