Felix Sturm
On 15 July 2006, Castillejo sprang back on the boxing scene by defeating younger Felix Sturm of Germany to seize the WBA middleweight belt in an exciting fight. Sturm, making his first title defense, was headed to a one-sided win until Castillejo (61–6, 41 knockouts) caught him with a left hook against the ropes with 13 seconds left in the 10th Round.
