In his first two title defenses, Holmes easily knocked out Alfredo Evangelista and Ossie Ocasio. His third title defense was a tough one. On June 22, 1979, Holmes faced future WBA Heavyweight Champion Mike Weaver, who was lightly regarded going into the fight sporting an uninspiring 19–8 record. After ten tough rounds, Holmes dropped Weaver with a right uppercut late in round eleven. In the twelfth, Holmes immediately went on the attack, backing Weaver into the ropes and pounding him with powerful rights until the referee stepped in and stopped it. "This man knocked the devil out of me", Holmes said. "This man might not have had credit before tonight, but you'll give it to him now."
