  Foreman turned professional in 1969 with a three-round knockout of Donald Walheim in New York City. He had a total of 13 fights that year, winning all of them (11 by knockout).
  
  In 1970, Foreman continued his march toward the undisputed heavyweight title, winning all 12 of his bouts (11 by knockout). Among the opponents he defeated were Gregorio Peralta, whom he decisioned at Madison Square Garden, although Peralta showed that Foreman was vulnerable to fast counter-punching mixed with an assertive boxing style. Foreman then defeated George Chuvalo by technical knockout (TKO) in three rounds. After this win, Foreman defeated Charlie Polite in four rounds and Boone Kirkman in three. Peralta and Chuvalo were Foreman's first world-level wins. Peralta was the number-10 ranked heavyweight in the world in January 1970 per The Ring, while Chuvalo was number seven in the world per their March 1971 issue.
  
  In 1971, Foreman won seven more fights, winning all of them by knockout, including a rematch with Peralta, whom he defeated by knockout in the 10th and final round in Oakland, California, and a win over Leroy Caldwell, whom he knocked out in the second round. After amassing a record of 32–0 (29 KO), he was ranked as the number-one challenger by the World Boxing Association and World Boxing Council.
