Alongside his current Mixed Doubles partner Katarina Srebotnik of Slovenia, he won the 2006 French Open crown with a straight-sets victory over Daniel Nestor and Elena Likhovtseva, 6–3, 6–4. At the 2006 Wimbledon Championships, Zimonjić reached the final of the Men's Doubles (alongside France's Fabrice Santoro) and the quarter-finals of the Mixed Doubles.
