He bounced back at the Monte Carlo Masters to reach the finals, where he earned his first top-10 wins of the year against Tommy Haas and Sébastien Grosjean, and he defeated Carlos Moyá in straight sets, 7–5, 6–3, 6–4, in the final to win the title. However, he was unable to keep his form, losing to Alberto Martín at the third round at Torneo Godó, losing to Ivan Ljubičić in the second round of Rome Masters, and the first round of the Hamburg Masters to Alberto Costa. These results made him fall out of the top 10 for the first time in a year. At the 2002 French Open, Ferrero reached his first Grand Slam final after upsetting No. 4 Andre Agassi 6–3, 5–7, 7–5, 6–3 and No. 2 Marat Safin 6–3, 6–2, 6–4. Despite being the strong favourite, he lost to compatriot Albert Costa, 1–6, 0–6, 6–4, 3–6. His foot was injured during the tournament, and he played through, taking some cortisone shots.
